Query: Quantitative analysis on the disparity of regional economic development
  in China and its evolution from 1952 to 2000   Domestic and foreign scholars have already done much research on regional
disparity and its evolution in China, but there is a big difference in
conclusions. What is the reason for this? We think it is mainly due to
different analytic approaches, perspectives, spatial units, statistical
indicators and different periods for studies. On the basis of previous analyses
and findings, we have done some further quantitative computation and empirical
study, and revealed the inter-provincial disparity and regional disparity of
economic development and their evolution trends from 1952-2000. The results
shows that (a) Regional disparity in economic development in China, including
the inter-provincial disparity, inter-regional disparity and intra-regional
disparity, has existed for years; (b) Gini coefficient and Theil coefficient
have revealed a similar dynamic trend for comparative disparity in economic
development between provinces in China. From 1952 to 1978, except for the
"Great Leap Forward" period, comparative disparity basically assumes a upward
trend and it assumed a slowly downward trend from 1979 to1990. Afterwards from
1991 to 2000 the disparity assumed a slowly upward trend again; (c) A
comparison between Shanghai and Guizhou shows that absolute inter-provincial
disparity has been quite big for years; and (d) The Hurst exponent (H=0.5) in
the period of 1966-1978 indicates that the comparative inter-provincial
disparity of economic development showed a random characteristic, and in the
Hurst exponent (H>0.5) in period of 1979-2000 indicates that in this period the
evolution of the comparative inter-provincial disparity of economic development
in China has a long-enduring characteristic.
