Pattern and Sustainability of China’s Economic Growth towards 2020∗ Xiaolu Wang, Gang Fan, and Peng Liu I. Introduction In this paper, we attempt to examine evidence and influential factors of changing economic growth pattern in China, and examine future growth sustainability towards 2020. China has maintained a high economic growth rate for nearly three decades, since the beginning of its economic reform in 1978. The average GDP growth rate during the period of 1979-2000 was 9.2%, and further accelerated to 10.1% from 2001 to 2006. GDP in real term by the end of 2006 has expanded to 13 times of that in 1978, reached US$ 2.62 trillion. However, economic growth in China has been described as “unsustainable” by economists (e.g., Paul Krugman, 1994) or “extensive pattern of growth” by Chinese government leaders (Premier Wen Jiabao, 2006), both meaning growth driven by massive input with limited technological progress or total factor productivity (TFP) growth. This pattern of economic growth in China can be characterized by very high rates of savings and investment, massive transfer of unskilled labor from the agricultural to urban non-agricultural sectors (which was the main source of TFP growth at the economy level), cheap labor cost, low level of labor education, low level of technical innovation, large income inequality, heavy dependency on external demand, inefficient energy consumption, heavy environment pollution, and so on. ∗ This paper is an outcome of the research project “Pattern and Sustainability of China’s Economic Growth”. The authors thank Mastcard for its financial support. 1 Nevertheless, some sighs of changing growth pattern was observed in recent years. Demand for skilled labor and professional workers is increasing, and supply of unskilled rural labor in some source regions is exhausted, both causing increases in labor costs. Workers’ education level is getting higher. There are shifts towards more capital intensive production. Some authors suggest that China’s economy development is now at the turning point (see e.g., Garnaut, 2006). Investment in R&D is still low, but its ratio to GDP doubled in the past decade, and is 1.3 percent in 2005. Both values of annual technical transactions in markets (in real term) and granted patents nearly quintupled during the same period. Some studies have identified higher growth of TFP or capital productivity at either the national or firm levels in recent years (see, e.g., Jefferson, Rawski and Zhang, 2007). Evidence shows that large, and increasing, income inequality is a main reason for relative weak domestic consumption growth and high savings rate. Some new policies has been adopted since 2004 to encourage rural income and consumption growth and to reduce poverty, such as abolition of agricultural tax, exemption of school fees in rural nine-year education, and improvement in rural and urban social security systems. It will be interesting to find out whether or how growth pattern in China is changing, and what will be the impact on growth in the future. To do so, we carry out empirical tests in this paper to examine possible effect of a number of potentially influential factors on growth, and use these results to forecast future growth in China towards 2020. In 2006, some modified historical GDP data, based on the new economic census, were published by the National Bureau of Statistics (NBS, 2006). GDP in 2004 were upward modified by 16.8%. GDP and GDP growth rate in earlier period were also adjusted accordingly. This enables us to get a more accurate growth accounting result. In section II, we review the roles of a number of influential factors in economic growth and their recent changes. Section III specifies a growth model for empirical tests and reports the results. Section IV carries out growth accounting to calculate contribution of factors to growth, and to forecast future economic growth towards 2020. Finally, Section V is the conclusion. 2 II. What Contributed to Growth and Do These Show Any Chang in Growth Pattern? Capital stock There has been an increasing rate of capital formation in the past, resulting from high savings and massive capital inflow. The average rate of capital formation rose from 35.2% of GDP in the 1980s to 40.2% in 2001-2005. Our calculated growth rate of fixed capital stock was 9.2% in average for the pre-reform period of 1952-1978, 10.6% from 1979 to 1998, and 12.8% from 1999 to 2005. In 2005-06 it was 15.6%. Rapid capital formation has played a major role in China’s economic growth. Because the savings rate remains high, capital growth rate is unlikely to slow down in the near future. We assume an annual rate of 15% in 2006-2010, and 14% in 2011-2020. Improvement in social security systems and reduction in income inequality can help to resume consumption and to moderate the rate of capital formation, but this depends on the government policies. Details of our calculation of capital stock, human capital stock and other variables can be seen in the notes of Table A1 in the Appendix. Labor and Human capital The increasing supply of unskilled cheap labor to industrial and service sector in the past two to three decades is an important source of China’s rapid economic growth. However, there has been some evidence showing that the trend is slowing down, and the labor cost is increasing. Meanwhile, the roles of human capital in economic growth are getting more important. While workers’ education level is increasing, skilled labor and professional workers are in short supply. Following Lucas (1988), human capital in this study is defined as effective labor that enhanced by their year of schooling. According to our calculation, average year of schooling of labor force is increasing. It was 6.1 years in 1980, 7.1 years in 1990, 8.6 in 2000, and 9.2 in 2005 (calculated from NBS data, various years; same below for unsourced data). However, average growth rate of human capital stock was diminishing, 7.3% in 1979-1988, 3.2% in 1989-1998, and 2.5% in 1999-2005. This was mainly caused by diminishes of labor growth rate, as the result of one-child policy. We expect fast increases in workers’ year of schooling in coming years due to expansion of tertiary and secondary vocational education, and improvement in rural nine-year education. Therefore 3 the current growth rate of human capital (around 2.6%) in 2006-2010 can be continued, and it may be slightly lowered to around 2% in 2011-2020. Marketzation Many evidences indicate that high economic growth during the reform period was benefited from the market oriented institutional changes, especially development of the non-state enterprise sector (private sector). Due to lack of overall historical data, shares of the non-state enterprise sector in industrial output are used in this study as a proxy of marketization. Data between 1996 and 1998 are found overstated, and data between 1999 and 2003 are not completed (small enterprises with annual sales below five million Yuan were missing). They are therefore modified according to data from the two industrial censuses in 1995 and 2004. According to the modified data, the shares of non-state enterprises were 22.4% in 1978, 43.2% in 1988, 63.8% in 1998, and 69.2% in 2005. Because many SOEs have already been privatized, further increase in the non-state share will be minor. We assume a three percentage point increase by year 2010, and another four percentage point increase by year 2020. Urbanization As one of the most important result of market oriented reform, urbanization was accelerated during the reform period, especially since the 1990s. The urbanization ratio, that is, urban share in total population, increased from 18% in 1978 to 43% in 2005, roughly meaning 300 million rural residents have transferred to urban areas. This has sustained increasing labor supply to the rapid growing industrial and services sectors. Meanwhile, reallocation of labor from sectors with low productivity to those with higher productivity became a major source of China’s productivity growth. In the past five years, the urbanization ratio increased at 1.4 percentage point per year. We expect same speed of increasing urbanization ratio from 2006 to 2010 to reach 50%, and possibly another ten percentage point or higher increase from 2011 to 2020 to reach at least 60%. Trade One of the most significant characteristics of China’s past growth pattern was export orientation. The trade dependency ratio, i.e., total value of exports and imports as a proportion of GDP, increased dramatically from 9.7% in 1978 to 63.9% in 2005. Economic theories state that trade contribute to productivity growth via exploitation of an 4 economy’s comparative advantages, may lead technological transfers among countries, and lead to efficiency increases via international competition. However, given the high achievement, we expect a slower increase in this ratio by annually two percentage points in 2006-2010, and then remain unchanged in 2011-2020. Foreign direct investment FDI has been another source of capital formation in China. It remains at the level of 5060 billion US dollars annually in recent years, making China one of the largest FDI recipient countries in the world. However, the growth rate of foreign capital diminished from above 30% in the 1990s to only 6% in 2005. In addition, compared with the huge domestic investment, FDI only accounts for a small part in China’s capital formation. Our calculation shows a nine percent or lower foreign share in total fixed capital stock in 20051. In this study, we assume an average 0.5 percentage point decrease of foreign share in total fixed capital stock between 2006 and 2010, and then a 0.3 percentage point decrease between 2011 and 2020. Foreign capital may contribute to TFP growth if it had a higher productivity than domestic capital, or transferred new technology to the economy, although an earlier study using foreign shares in total investment in fixed assets did not find significant contribution of FDI to TFP (Wang, 2006). To further test these effects, we calculate foreign capital stock and use the foreign share in total capital stock in the model. A positive and significant estimate indicates a higher productivity of foreign capital than total capital, thus a contribution to TFP growth. Infrastructure Better infrastructure makes more efficient use of other factors. In the past decade, there was a rapid improvement in infrastructure conditions, especially the highway system. The length of highway increased from 1157 thousand (1995) to 1930 thousand km (2005). The quality of the road system also much improved. Of the total length of highway, freeway increased from 2 to 41 thousand km. To make the data comparable, we converted different grade of road length into a grade II equivalent highway length according to the road capacity of transport volumes. In this study, it is called standard 1 There should be a deduction of the part invested for working capital from total FDI. However, data are unavailable. Therefore the share of nine percent is an upper limit. 5 highway length. The standard highway length increased dramatically in the past decade, from 275 thousand (1995) to 830 thousand km (2005). Infrastructure investment forms part of total capital stock, and contribute to economic growth via growth of capital. Meanwhile, improvement in infrastructure may also generate externalities to the economy and therefore contribute to TFP growth. To test this effect, we calculated a ratio of standard highway to population. This ratio was 23 km per thousand persons in 1995, 44 km in 2000, and 64 km in 2005. In the future, growth of natural length of highway will slow down, but quality improvement in the road system will continue. We assume another 15 km increase in this ratio in 2006-2010, and 20 km further increase in 2011-2020. Research, development and technical innovation R&D in China was government-leading and generally at a low level in the earlier stage even during the reform period. No significant contribution of R&D on growth was found. However, the recent trend shows increases in fund raising for science and technology activities, mainly led by enterprises. The funds raised by enterprise accounted for 44% of the total in 1995, increased to 66% in 2005. During the same period, R&D expenses as a proportion to GDP increased from 0.60% to 1.34%, and total patents granted increased from 45 to 214 thousand items per year (data are from NBS, 2006 and 2005b). The increase in enterprise spending is a clear evidence for positive market returns to R&D. One can expect that the ratio of R&D expenses to GDP will continue to increase in the future until achieve a reasonable level, possibly around 3%. This implies an accelerated growth of R&D expenses until the middle of 2020s. Structural bias Although high saving and investment have contributed largely to economic growth, the continued decreases in the share of final consumption in GDP have drawn much concern from economists and the government. From 1980 to 2005, the share of final consumption in GDP dropped from 65.5% to 51.9%; and the share of private consumption dropped from 50.8% to 38.0%. A major drop of final consumption, by ten percentage points, occurred in recent years from 2001 to 2005. Due to relative weak consumption growth, the rapid increasing production capacity relies more and more on investment demand and net export to be utilized, and leading more 6 trade disputes with other countries. Net export is increasing, accounting for 6.7% of GDP in 2006. Foreign exchange reserves, resulted from both trade surplus and capital inflow, mounting up to 1.066 trillion US dollars by the end of 2006; a large part of which was used to buy US treasure bonds. Balance of bank deposit is huger, reached 33.54 trillion Chinese Yuan, or 1.6 times of GDP by the end of 2006. The ratio of total bank loans to bank deposit dropped from 93.8% in 1995 to 67.8% in 2005. All these indicates inefficient uses of resources. A number of factors are responsible for weaker consumption growth. Firstly, income inequality is getting larger. The Gini coefficient was around 0.30 in early 1980s, then 0.45 in 2001. Larger income gap caused more savings and less consumption because the saving rates are uneven between rich and poor. Secondly, public services on education, healthcare and housing were largely withdrawn during the reform period, and social security systems are incomplete, causing heavy burden and future uncertainties to, and forced savings of, middle and low income people. Finally, due to incompletion of the taxation system, enterprise savings, from undistributed profits, were built up to a huge amount. In short, the continued decreases in final consumption ratio are results of institutional defects, calling for public sector reforms. Recently, the government adopted a number of policies to restore consumption growth, including abolition of agricultural tax, exemption of school fees for rural nine year education, more government expenses on poverty reduction, and improvement in social security systems. These will certainly have a positive impact on final consumption. However, whether these are enough to turn back the decreasing trend of consumption ratio is still uncertain. Improvement in public sector governance is more basic. In this study, we define the ratio of final consumption in GDP as a structure variable, and hypothesize that it had a negative effect on economic growth when dropped below a certain level. This hypothesis will be empirically tested. Government administration cost As a result of inefficient use of public resources and possible corruption, the government administration expenses, as a part of fiscal expenditure, is increasing. It accounted for 1.35% of GDP in 1978, 1.80% in 2000, then increased to 2.63% in 2005. This figure exclude the operating cost of government departments and their subordinates in the areas 7 such as agriculture, industry, transport, communication, commerce, culture activities, publication, education, healthcare, public medication, sports, sciences, social sciences, government and party training, and superannuation of retired administrative persons. With these included, it mounts to 1.35 trillion Yuan in 2005, accounting for 7.4% of GDP. Inefficient and inadequate use of public resources may form some deduction from economic growth and TFP changes. In this study, fiscal expenses on government administration (the narrow sensed) as a ratio to GDP is used to test this possible effect. The increases in administration cost may be treated as a reflection of a wider range of government activities with low efficiency, including government investment and government distribution of other public resources. In this study, the same trend of increases in the share of administrative cost in GDP is assumed to continue in the future till 2010, and slightly slower increases in 2011-2020, as a result of possible improvement in government administration, is assumed. Different scenarios are also simulated. III. Empirical Tests In an earlier study, Wang (2006) estimated contribution of a number of factors to economic growth. A similar method is used in this study with modifications of the model to examine the roles of more factors played in China’s economic growth. A Lucas typed growth model is employed for the study. We use time series data at the national level from 1952 to 2005. Most of the data, except those otherwise referenced, are calculated from China Statistical Yearbook (NBS, various years) and China Compendium of Statistics 1949-2004 (NBS, 2005b). Original input and output data used in this study are shown in Table A1 in Appendix at the end of the paper. The basic empirical model is specified as follows: lnY(t)=C+a1lnK(t)+a2lnH(t-3)+a3Ha(t)+R(t) (1) where Y(t) is GDP in 1978 constant price at year t; K(t) is fixed capital stock in 1978 constant price at year t; H is human capital stock or effective labor that is defined as total labor force enhanced by their year of schooling; Ha is works’ average year of schooling for possible spillover effect of human capital on economic growth, C is the intercept term, and R(t) is the residual term, which contains both unexplained TFP changes and random 8 errors (thus, without inclusion of other related variables, there should be an autocorrelation problem). This is much the same as Lucas (1988) model except a few modifications. First, lnHa is replaced by Ha so that the effect of workers’ average year of schooling can be explicitly measured. Second, the residual R(t) is not simply defined as a random error term, since, obviously, Ha can not catch the entire TFP change. Third, human capital H takes a threeyear lag in this model. This is because our preliminary study using a distributed lag model found a largest and most significant coefficient of lnH with three-year lag. This is reasonable since H is only education-enhanced human capital without considering the learning-by-doing effect. Experiences tell us that school graduates usually become more productive a few years after they being employed. It is therefore reasonable to believe that the three-year lag of lnH is a best representative of human capital stock in our case. To test the possible effects of technical innovation, marketization, urbanization, foreign investment, foreign trade, and government administration cost on TFP growth, above model is expanded into the following form: lnY(t)=C+a1lnK(t)+a2lnH(-3t)+a3Ha(t)+a4DlnRK(t)+a5m(t)+a6u(t)+a7fk(t)+a8td(t) +a9ga(t)+a10hw(t)+ε1(t) (2) where RK is a research capital stock that is accumulated by R&D investment. Due to insignificance of lnRK in a preliminary estimation, we take its first difference, i.e., DlnRK, in the model. According to this specification, a significant estimate of it meaning that only an accelerating growing RK contributes to economic growth. m is the share of nonstate sector in industrial output as a proxy of marketization; u is the urbanization ratio, that is, the share of urban population in total; fk is the share of foreign capital in total capital stock; td is the trade dependency ratio; ga is the government administration cost as a proportion to GDP; hw is the highway-population ratio; and ε1 is a random error. In an alternatively model, we hypothesize that economic growth was restricted by a structural bias, i.e., too low final consumption and too high saving and investment results in overcapacity of production. This may work as a deduction of TFP. To test this hypothesis, a structure variable fc, i.e., the ratio of final consumption in GDP, and its quadratic term, is included in Model 3: lnY(t)=C+a1lnK(t)+a2lnH(-3t)+a3Ha(t)+a4DlnRK(t)+a5m(t)+a6u(t)+a7fk(t)+a8td(t) 9 +a9ga(t)+a10hw(t)+a11fc(t)+a12fc2(t)+ε2(t) (3) To impose a restriction for constant-returns-to-scale hypothesis (a2=1-a1), both Y(t) and K(t) are divided by H(-3t), so Model 3 can be transformed into the following version: lny(t)=C+a1lnk(t)+a3Ha(t)+a4DlnRK(t)+a5m(t)+a6u(t)+a7fk(t)+a8td(t) +a9ga(t)+a10hw(t)+a11fc(t)+a12fc2(t)+ε3(t) (3’) where lny(t)=lnY(t)-lnH(-3t), and lnk(t)=lnK(t)-lnH(-3t). We also want to investigate possible changes in productivity of capital and human capital. For this purpose, both the capital and human capital variables are multiplied respectively by three dummy variables for the first and second decades of the reform periods and the most recent period (1979-1988, 1989-1998, and 1999-2005). Below is the modified Model: lnY(t)=C+a1lnK(t)+a1’lnK1979-88(t)+a1’’lnK1989-98(t)+a1’’’lnK1999-2005(t)+a2lnH(-3t) +a2’lnH1979-88(-3t)+a2’’lnH1989-98(-3t)+a2’’’lnH1999-2005(-3t)+a3Ha(t)+a4DlnRK(t) +a5m(t)+a6u(t)+a7fk(t)+a8td(t)+a9ga(t)+a10hw(t)+a11fc(t)+a12fc2(t)+ε4(t) (4) where, for instance, lnK1979-88(t)=lnK(t) for years from 1979 to 1988, and lnK1979-88(t)=0 for other years. The coefficient a1’, for instance, indicates changes of a1 in the period 19791988. Therefore for this period, the elasticity of capital should be a1+a1’. In Table 1, empirical results of the models defined above are reported, which are obtained from Prais-Winsten AR(1) Regressions. 10 Table 1.

Those with ’ are significant at the 10% level, with * are at the 5% level, and with ** are at the 1% level. 11 In Model 1, both capital and human capital show significant contribution to economic growth, and the estimated spillover effect of human capital is negative and insignificant. As expected, the Durbin-Watson statistic indicates existence of autocorrelation, therefore unreliable estimates. Model 2 produces better results after including a number of relevant variables. Estimates of capital, human capital, marketization, difference of research capital, and government administration cost (negative) are significant. Others are insignificant; they are spillover effect of human capital, the urbanization ratio, foreign capital share, trade dependency ratio, and highway-population ratio. Durbin-Watson statistic is much improved from Model 1. It is in an inconclusive interval but close to dU. Model 3 rejects the null hypotheses and confirms the negative impact of the structural bias. The estimate of final consumption ratio, fc, is positive and significant; and the estimate of its quadratic term is negative and significant. This indicates an invert U-shape curve for effect of final consumption ratio on economic growth: positive before a certain critical point and negative after that point. Figure 1 illustrates this effect using the estimated coefficients of fc and fc2, for an interval of fc between 90% to 10%. Shown by the simulated curve, the critical point of final consumption in GDP is around 55%. According to this result, the current final consumption ratio, 51.9% (year 2005), already has a negative effect on economic growth; and the current trend of changing fc indicates a greater negative effect on growth in the future. 12 Figure 1.

Model 3 also shows further improvement in Durbin-Watson statistic. As a result, the spillover effect of human capital, urbanization, share of foreign capital, trade dependency, and per capital standard highway all become significant at least at the 10% level (only for the trade dependency ratio). All the other estimates are significant at either 1% or 5% levels. The restricted version of the model for constant returns to scale (Model 3’) and the model with periodical dummies on capital and human capital (Model 4) obtained very similar estimates to Model 3, except that the spillover effect of human capital is smaller or becomes negative and insignificant (indifference from zero in Model 4), due to that more contribution is attributed to capital and the own effect of human capital, and the DurbinWatson statistic for Model 3’ is lower. Results of Model 4 show significant increases in returns to both capital and human capital during the reform period. Returns to capital increased by 0.0167 in the 1999-2005 period compared with the average of pre-reform period, and returns to human capital increased by 0.0131 in the 1999-2005 period. These equal to a five-percent increase in marginal productivity of capital and two-percent increase in marginal productivity of human capital. Using statistical data and estimates of Models 2, 3, 3’ and 4 to simulate economic growth for the past periods, all the three models provide generally good simulations, but Model 3 13 provides the closest ones compared with the actual growth rates. Especially, the simulated average GDP growth rate for the recent two periods, i.e., 1989-1998, and 19992005, are only -0.05 and -0.2 percentage points away from the actual growth rates. The estimated parameters from Model 3 are therefore used in growth accounting in the next section. Table 2 compares different simulation results. Statistics for growth of inputs and contributing factors in different periods can be seen in Table A2 in Appendix. Table 2.

IV. Growth Accounting Based on the estimates of above and statistical data, the author carries out growth accounting to decompose economic growth rate into different sources for different period. Table 3 shows the result. Contribution of inputs and productivity changes to economic growth are calculated. The result indicates that capital and human capital growth (or, input-driven growth) have played a crucial role in driven economic growth in the past, both pre-reform and reform periods. It contributed 5-6 percentage points in most periods in the past. TFP growth contributed a neglected 0.3 percentage point to growth in the pre-reform period, increased significantly to 3.3 percentage points in the early stage of the reform period, and then between 3.7 - 4.4 percentage points in the later stage of the reform period until 2005. 14 Most important sources of TFP growth during the whole reform period was marketization and urbanization, they together made average 1.5 – 1.7 percentage point contribution to TFP growth. The market-oriented institutional changes lead to increasing efficiencies via factor reallocation and better incentive system, and urbanization also leads to reallocation of labor and other resources from the low-productivity agricultural sector to higherproductivity urban non-agricultural sectors. The results show that, while the effect of marketization diminishing, the urbanization effect increased to 1.3 percentage point in recent years. The effects of foreign investment and foreign trade, via spillover of technology and management skills, together contributed only 0.6 percentage point to TFP growth in the earlier reform period, then increased to 1.0 - 1.3 in the 1990s and recent years. While the foreign share in total capital stock is decreasing in recent years, the effect of foreign trade is playing a more important role in TFP growth, made 1.3 percentage point contribution to TFP. Nevertheless, one can hardly separate the demand effect that driven by export growth from the effect of trade-sourced productivity growth. Spillover effect of human capital was also found to make important contribution to TFP growth, at 0.8-1.0 percentage point. Infrastructural improvement, reflected by growth of per capital highway, made little, but increasing, contribution to TFP growth in the 1980s and 90s. It became important source of TFP growth in recent years, i.e., 1.3 percentage point. While research capital (i.e., accumulated R&D investment that calculated by Perpetual Inventory Method) was not found to have significant impact on growth, its annual difference is significant. This suggests that the faster accumulation of research capital has lifted up economic growth rate to some extent. The effect is positive but very small in the 1990s, and then increased to 0.5 percentage point in recent years. Considering the fact that either the research capital stock or the annual R&D expenses is still fairly small, this is likely an indicator for growth effect of technical innovation in the future. The high administration cost made an increasing negative impact on economic growth. It reduced TFP growth by 0.1 percentage points in the 1980s and 1990s, but this effect jumped to -1.7 percentage points in recent years, heavily reduced TFP growth. 15 One should note that, the negative effect of the structural bias on growth and TFP changes only exists when the final consumption ratio in GDP falls below the estimated critical point of 55%, because in this situation it reduce economic efficiencies. However, when it varies in the range above 55%, its impact on growth is actually via the effect of changing savings and investment, and therefore should be reclassified as a part of contribution by growth of capital. In Table 3, this was added back to input-driven growth as a part of capital contribution. The final consumption ratio dropped dramatically from 62.3% in 2000 to 54.3% in 2004, then to 51.8% in 2005. This made negative contribution to economic growth in 2005, but not explicitly reflected in the average contribution in the period of 1999-2005. A continuation of the current trend will lead to further drop of the ratio in the coming a few years, although will be moderated by the government policy reinforcing income redistribution and poverty reduction. There is a small part of unexplained TFP growth for different periods, i.e., differences between the actual and simulated growth rates. It was negative in the pre-reform period, indicating a technical deterioration, half percent in the earlier reform period (which was likely a unexplained allocative effect leading by rapid rural industrialization in that period), diminished to a neglectable level in the 1989-1998 period, and then increased to 0.21% in recent years. The recent change may be considered as a result of technical progress that was not indicated by the effect of research capital growth. Table 3.

The above result rejects the judgment on China’s economic growth as “input-driven growth without productivity changes” (see, e.g., A. Yang, 2000; P. Krugman, 1994). It clearly indicates a 3-4 percentage point TFP growth during the reform period. Meanwhile, it also shows that one-third or half of the TFP growth was from “allocative effect”, i.e., productivity growth induced by improvement in factor allocation. This effect is reflected by contribution of marketization and urbanization. Economic theories have proved that reallocation of economic resources is a short run effect which does not sustain a high growth rate in the long run, although urbanization effect in China is unlikely to diminish in the next 10-15 years. Similar role may be attributed to contribution of infrastructural improvement. It generates positive externalities to the economy, may continue to push up economic growth in the coming decades or so, but the effect on growth rate may not be sustainable in the ‘long run’ that defined in growth theories. Another important part of TFP growth, at least one percentage point, was identified as spillovers of technology and management skills from foreign investment and foreign trade. This is partially a sustainable source of growth since it injects new technology into the economy. However, sustainability of these effects on growth is discounted to some extent because the source of TFP is not endogenously generated. A new finding in this study is that the increasing R&D expenses and the spillover effect of human capital made important contribution to TFP growth, accounting for 1.3 percentage points in 1999-2005. With inclusion of the unidentified TFP growth, which should be considered as normal technical innovations that did not reflected from the effect of increasing research capital, their total contribution to TFP was 1.5 percentage points. This is a clear signal to indicate high possibility of changing growth pattern towards a more sustainable way in the future. 17 While optimistic results were obtained, the outcome of growth accounting also delivers some pessimistic massages on economic growth. The first one is the significant negative effect of government administration cost on economic growth, which made a 1.7 percentage point deduction to growth and productivity changes during the 1999-2005 period. This indicates that government inefficiency and corruption is becoming a serious threat to sustainability of economic growth. The second one is insufficient domestic consumption, which already made deductions to economic growth in 2005, and likely to further restrict economic growth in the near future. These two effects make uncertainties to future economic growth. Based on these results, economic growth in 2006-2010 and 2011-2020 is projected in the following in two scenarios. The basic scenario is obtained generally based on the current trend of changing contributing factors. The alternative scenario makes two optimistic assumptions on changing government efficiency and increasing final consumption, as results of government reform, with other conditions the same as in first scenario. For the 2011-2020 period, the effect of increasing R&D is assumed to be zero, and a same effect is attributed to a common technical progress and added to the item: TFP from unidentified factors. The two scenarios are compared in Table 4. Predictions and assumptions on changing contributing factors can be seen in Table A2 in the appendix. Table 4. Growth forecasts: different scenarios (annual growth rate, %) Basic Scenario (I) Alternative Scenario (II) 2006-10 2011-20 2006-10 2011-20 5.84 5.12 5.84 5.12 By capital 4.31 3.94 4.31 3.94 By human capital 1.53 1.18 1.53 1.18 1.58 0.10 3.64 3.34 Spillover effect of human capital 0.74 0.74 0.74 0.74 Increasing R&D expenses 0.47 0.00 0.47 0.00 Marketization 0.19 0.13 0.19 0.13 Urbanization 1.35 1.08 1.35 1.08 -0.59 -0.35 -0.59 -0.35 0.58 0.00 0.58 0.00 -1.73 -1.73 0.00 1.15 0.88 0.59 0.88 0.59 Input-driven growth TFP from identified factors Foreign capital effect Foreign trade effect Government administration cost Infrastructure effect 18 Effect of structural bias -0.31 -0.35 0.00 - TFP from unidentified factors 0.40 0.80 0.40 0.80 Projected growth rate 7.82 5.92 9.88 9.26 Source :Same as Table 2. There are two differences in assumptions used for the two scenarios: First, in the basic scenario, the author assumes that government administration cost as a share in GDP will continue to expand in 2006-2010 and 2011-2020 at the same rate as in 1999-2005, i.e., increase by 0.15 percentage point per year, whereas in the alternative scenario, it is assumed to stop expansion in 2006-2010, and decrease by 0.1 percentage point per year in 2011-2020 as a result of possible government reform and therefore increasing government efficiency. Second, the author assumes that, in the basic scenario, the share of final consumption in GDP will continue to decrease, resulting from further expansion of income inequality in initial income distribution, but at a slower rate, due to increases in government transfer payment. In 2000-2005, this ratio actually dropped by 10.5 percentage points. It is assumed to further decrease by 5.0 percentage points in 2006-2010, and another 5.0 percentage points in 2011-2020. In the alternative scenario, the consumption ratio is assumed to be stable in 2006-2010, and increase to 55% in 2011-2020. This is considered as a result of a series policy adjustment toward a more healthy income distribution and improvement in social security systems and public services. The results of the two scenarios are very different. In the first scenario, economic growth rate will drop from average 9.5% (2000-2005) to 7.8% (2006-2010), then to average 5.9% (2011-2020). The rapid growth period since 1978 will end in the 2020s. In the second scenario, economic growth rate will be sustained at 9.9% in 2006-2010, and 9.3% in 2011-2020. A continued rapid growth in longer term can be expected. V. Conclusion In this study, the author examines China’s economic growth pattern in the past and future and growth sustainability towards 2020. Empirical study using a Lucas typed growth model and data after statistic revisions identifies a 3-4 percentage point TFP growth 19 during the past period of economic reform from 1978 to 2005. Of which, 1.5-1.7 was contributed by marketization and urbanization during the whole reform period, mainly via improvement in factor allocation; 1.0-1.3 was contributed by spillover effect of international trade and foreign direct investment since the 1990s; 1.3 was contributed by externalities from improvement in infrastructure in most recent years. Increases in R&D expenses and spillover effect of human capital together contributed 0.8 percentage point in the 1980s, 1.0 in the 1990s, and 1.3 in most recent years, indicating an increasing trend of technological progress. Two negative impacts on TFP growth are identified. One negative impact is the increasing government administration cost, representing effect of government inefficiencies and corruptions, which was found to make a rapid increasing deduction to TFP growth, accounts for -1.7 percentage points in recent years. Another is a structural bias, i.e., continued drop of the share of final consumption in GDP, which started to generate negative impact on GDP growth in the immediate past years. The effect of the structural variable is found to be non-linear. The effect of diminishing consumption ratio is positive above a critical value around 55%, and turns into negative after dropping below this point. Based the result of growth accounting and analysis on changes in various contributing factors, economic growth rate is projected for the periods of 2006-2010 and 2011-2020. It suggests a continued trend of growth driven by inputs in the two coming periods with minor decreases, a diminishing contribution of marketization but a continued strong contribution of urbanization and infrastructure improvement, and a continued, if not further increasing, contribution of TFP growth by R&D, human capital spillover, and other sources of technical innovation. Changes in the government administration cost and final consumption are found to be crucial determinants for future growth. With the current trends of increasing government administration cost and decreasing final consumption, economic growth rate will be around 7.8% in average of the 2006-2010 period, and then drop to an average level of 5.9% in 2011-2020. The rapid growth period since 1978 will end in the 2020s. However, with possible increases in government efficiency via government reforms, and recovery of domestic consumption that can be induced by improvement in public services, social 20 security systems, and more equity of income distribution, economic growth can be sustained at above 9% level in both the 2006-2010 and 2011-2020 periods. A more sustainable and continued rapid growth in longer period can be expected. 21 References: Chow, G.

Modifications were made to employment data, because there was originally a large gap between the 1989 and 1990 statistics on total employment, equals to 17% of the 1989 employment. This was a result of data inaccuracy between the two national population censuses in 1982 and 1990. Data for the period of 1983-1989 are modified accordingly. 2. Fixed capital stock is calculated using historical data of total investment in fixed assets and price index for fixed investment, using a Perpetual Inventory Method (see Wang, 2006). To avoid shortage of data on various categories of capital stock, an overall depreciation rate of 5% is used for the pre-reform period. Some studies found faster capital depreciation during the reform period. In this study, we adopt a final 9.6% rate that recommended by Zhang Jun (2007), but assume it was gradually achieved during the 1979-1992 period with a 0.3 percentage point change per year. For the initial fixed capital stock in 1952, we take RMB 70 billion (in 1978 price), mainly based on Chow (1993). He calculated that capital stock in the non-agricultural sectors was 58.3 billion Yuan in 1952 (1952 price), of which fixed capital was 31.6 billion, and capital stock in the agricultural sector was 45 billion including non-fixed capital. We assume 70% of total agricultural capital being fixed capital, and upward modify the total fixed capital by 10% with consideration that Chow’s capital stock maybe more or less underestimated due to data incompletion, we get a total 69.4 billion fixed capital stock in 1952 at 1952 price (see Wang, 2006). 3. Foreign direct investment data are used for calculation of foreign capital stock. They are converted to Chinese Yuan at the official exchange rates and deflated using Fixed Asset Investment Price Index of the NBS. A depreciation rate of 9.6% is assumed. 4. The research capital is defined as an accumulation of knowledge and technology, and approximately measured by the accumulated expenses on R&D at constant prices. Because of data incompletion, and considering that enterprise expenses on R&D were rare in earlier period, we use fiscal expenses on science and technology for the period before 1990. Data are deflated into 1978 prices using a GDP deflator. The invisible depreciation rate is assumed to be 8%. 5. Annual formation of human capital from 1952 to 2005 is calculated from graduation and enrollment data (with one education-period lag) of all kinds of schools, from primary to postgraduate education. The calculation referenced the information from the four national population censuses in 1964, 1982, 1990 and 2000. Unfinished school education (i.e., the differences between graduation and period lagged enrollment) is assumed to have an average 50% length of the corresponding education period. Vocational education, adult education, special education, overseas study, and informal training programs are also included. Human capital depreciation is calculated based on the death rate of the population and the calculated average year of schooling of population (not of labor force) with time lag. The initial human capital stock in 1952 is projected as average 1.3 year of schooling of the total population. This is based on 1964 national census data on education and detailed education data between 1952 and 1964. 6. Workers’ average year of schooling is calculated using human capital and employment data. 24 Table A1. continued 1952 9031 Urbanization ratio Urban/total population 0.1246 1953 10049 0.1331 0.5700 1954 11004 0.1369 0.5290 1955 12930 0.1348 1956 17946 1957 20700 1958 Year Standard highway km Non-state share In industrial output 0.5850 Non-state share (adj) In industrial output 0.5850 Trade ratio To GDP Administration cost To GDP Final consumption To GDP 0.0951 0.0214 0.7892 0.5700 0.0982 0.0213 0.7723 0.5290 0.0986 0.0213 0.7447 0.4870 0.4870 0.1207 0.0206 0.7726 0.1462 0.4550 0.4550 0.1057 0.0235 0.7471 0.1539 0.4620 0.4620 0.0978 0.0203 0.7409 35134 0.1625 0.1080 0.1080 0.0985 0.0165 0.6603 1959 43319 0.1841 0.1140 0.1140 0.1038 0.0185 0.5660 1960 45347 0.1975 0.0940 0.0940 0.0881 0.0192 0.6184 1961 42626 0.1929 0.1150 0.1150 0.0743 0.0219 0.7803 1962 42316 0.1733 0.1220 0.1220 0.0704 0.0189 0.8379 1963 44323 0.1684 0.1070 0.1070 0.0695 0.0191 0.7844 1964 45662 0.1837 0.1050 0.1050 0.0671 0.0173 0.7481 1965 50054 0.1798 0.0990 0.0990 0.0632 0.0148 0.7111 1966 53977 0.1786 0.1000 0.1000 0.0680 0.0139 0.6848 1967 56471 0.1774 0.1150 0.1150 0.0633 0.0129 0.7470 1968 59054 0.1762 0.1160 0.1160 0.0630 0.0133 0.7429 1969 63243 0.1750 0.1130 0.1130 0.0552 0.0128 0.7318 1970 68311 0.1738 0.1240 0.1240 0.0501 0.0112 0.6614 1971 73820 0.1726 0.1410 0.1410 0.0498 0.0127 0.6512 1972 77895 0.1713 0.1510 0.1510 0.0583 0.0138 0.6701 1973 81078 0.1720 0.1600 0.1600 0.0810 0.0131 0.6560 1974 85082 0.1716 0.1760 0.1760 0.1047 0.0132 0.6608 1975 91919 0.1734 0.1890 0.1890 0.0969 0.0130 0.6397 1976 98232 0.1744 0.2170 0.2170 0.0897 0.0139 0.6635 1977 103777 0.1755 0.2300 0.2300 0.0851 0.0135 0.6500 1978 109763 0.1792 0.2240 0.2240 0.0974 0.0135 0.6210 1979 109734 0.1896 0.2150 0.2150 0.1119 0.0141 0.6435 1980 112613 0.1939 0.2402 0.2402 0.1254 0.0147 0.6549 1981 116457 0.2016 0.2520 0.2520 0.1503 0.0145 0.6711 1982 119813 0.2113 0.2560 0.2560 0.1449 0.0153 0.6645 1983 123364 0.2162 0.2660 0.2660 0.1442 0.0171 0.6638 1984 127735 0.2301 0.3090 0.3090 0.1666 0.0174 0.6582 1985 133571 0.2371 0.3514 0.3514 0.2292 0.0145 0.6595 1986 141596 0.2452 0.3770 0.3770 0.2511 0.0164 0.6492 1987 152505 0.2532 0.4030 0.4030 0.2558 0.0149 0.6357 1988 164196 0.2581 0.4320 0.4320 0.2541 0.0147 0.6394 1989 173701 0.2621 0.4390 0.4390 0.2446 0.0154 0.6449 25 1990 184691 0.2641 0.4539 0.4539 0.2978 0.0162 0.6249 1991 193751 0.2694 0.4383 0.4383 0.3317 0.0158 0.6242 1992 206101 0.2746 0.4848 0.4848 0.3387 0.0158 0.6241 1993 224837 0.2799 0.5305 0.5305 0.3190 0.0152 0.5929 1994 245657 0.2851 0.6266 0.6266 0.4229 0.0151 0.5823 1995 274513 0.2904 0.6603 0.6603 0.3866 0.0144 0.5813 1996 304256 0.3048 0.6368 0.6217 0.3391 0.0146 0.5922 1997 444028 0.3191 0.6838 0.6487 0.3415 0.0144 0.5895 1998 391918 0.3335 0.7176 0.6379 0.3181 0.0157 0.5962 1999 439258 0.3478 0.5108 0.6376 0.3334 0.0170 0.6116 2000 554138 0.3622 0.5267 0.6359 0.3958 0.0180 0.6230 2001 579256 0.3766 0.5557 0.6446 0.3847 0.0200 0.6137 2002 639305 0.3909 0.5922 0.6602 0.4270 0.0248 0.5957 2003 693469 0.4053 0.6246 0.6736 0.5189 0.0253 0.5678 2004 756825 0.4176 0.6519 0.6841 0.5976 0.0254 0.5430 2005 831022 0.4299 0.6672 0.6919 0.6386 0.0263 0.5186 Note (continued): 7.
