Cross-sectional data refers to data collected by observing many subjects (such as individuals, firms or countries/regions) at the same point of time, or without regard to differences in time. Analysis of cross-sectional data usually consists of comparing the differences among the subjects.

Ka-fu Wong © 2007 Production grew rapidly in the early 1990s and, by 1995, it exceeded the production peak in 1981 in Japan, which had been the largest producer in the world. The export of motorcycles, mainly to Asia and Africa, began when the growth of domestic consumption stagnated in the late 1990s. Exports have increased rapidly since 2000 reaching three million in 2003, which accounts for 20.6% of the total number of motorcycles produced. (However, these data do not cover small producers operating without government permission.) ECON1003: Analysis of Economic Data Lesson0-19 Example Township and village enterprises in China The figure illustrates changes in employment and output value of TVEs in addition to their importance in the national economy over a twenty-year period. The share of TVE output in GDP is measured by the ratio of TVE valueadded to national GDP of secondary industry. Initially, COEs were more important than PEs in terms of number of employees and output value but, over time, their positions reversed. Employment in COEs declined to less than 40 million following the record high level reached in 1995 of more than 60 million. By contrast, the employment of PEs shows an upward trend during the period and reaches nearly 100 million by 2002, which accounts for around 20 percent of the rural labor force. Likewise, aggregate output of COEs stagnated at around four trillion yuan since the mid-1990s, whereas the output of PEs grows rapidly from 1992 and reaches nine trillion yuan in 2001. This growth of TVEs is attributable to both enterprise privatization and the establishment of private enterprises.

Ka-fu Wong © 2007 ECON1003: Analysis of Economic Data The plotted log-income differences may be interpreted crudely as returns to schooling. Assuming a schooling gap between elementary-school and college graduates of 10 to 12 years, the implied marginal rate of return per year of schooling for college graduates was approximately 5.5% shortly after the beginning of the Communist era and it decreased to about half that in the very early years of reform. After reform, the earnings premium for college education accelerated sharply beginning around 1990. Lesson0-21 Example Regional disparities in China On average, the coastal regions registered relatively higher growth than the inland provinces following the reforms and into the 1990s. Although the inland regions experienced growth similar to that of the coastal regions during the 1980s, these regions fell considerably behind their coastal counterparts during the 1990s when real GDP per capita increased by only 95 percent in the inland regions but by 144 percent in the coastal regions. In fact, GDP per capita in purchasing power terms in the coastal regions began to catch up with that of the Southeast Asian emerging economies, e.g., Malaysia, Philippines, Indonesia and Thailand, in the early 1990s and even surpassed that of these countries in 1996 Fu, Xiaolan (2004): “Limited linkages from growth engines and regional disparities in China,” Journal of Comparative Economics 32: 148–164.
