20世纪90年代中国县际经济差异的空间分析

首次将县域经济发展数据与图形数据结合分析，结果表明1990－1998年中国县域经济发展相对差异明显较小，但沿海地区与内陆地区的差异则出现扩大；经济增长较快的县域自一些增长中心向外扩延，逐步形成沿海岸带，京广线和长江沿岸三大经济增长轴；但沿海发达区内存在十分不发达县域，经济不发达县域主要位于西部地区，与环境较差的山区，寒区，旱区以脑省际边界地区有关；全国县域经济基础和增长可分为基础好增长较快型，基础差增长较快型，基础差缓慢增长型，基础好缓慢增长型。

County Level Economic Disparities of China in the 1990s

This paper analyses regional economic disparities in China using nationwide county level data. Firstly, in contrast to the enlarging trend indicated by provincial level studies, economic disparities between counties were narrowed in the 1990s. This finding does not apply in the comparison between coastal and inland areas. The disparities between the two parts were continuously widened. Secondly, the counties with faster growth rates than the national average were spread from several growth centers to outside. Consequently, three growth corridors gradually appeared, namely, the Coastal Corridor (along the nation's coastal line), Beijing-Guangzhou Corridor (along the railway from Beijing to Guangzhou), and the Changjiang River Corridor (along the Changjiang River from Chengdu to Shanghai). Thirdly, regional disparities exist within each corridor. There were numbers of relatively underdeveloped counties in the Coastal Corridor. Similarly, relatively developed counties were found in Western China. Fourthly, general speaking, the less developed counties were mainly located in the western part of China. The distribution pattern of less developed counties is consistent with the disadvantageous development conditions in mountainous, cold and dry areas, as well as with the isolation in the provincial border regions. Finally, this paper classifies counties into four categories by using their development status in 1990 and their growth rates from 1990 to 1998.
