欠发达地区经济空间结构及其经济溢出效应的实证研究——以河南省为例

The Evlutin of Spatial Economic Structure in the Less Develped Region and Its Effects on Regional Economic Growth: the Case of Henan Prvince

以县域为基本空间单元,以人均GDP为衡量指标,分析了河南省经济空间结构演变过程,结果表明,20世纪90年代以来,河南省经济正处于空间集聚过程,经济空间结构呈现出明显的中心———外围模式。通过建立模型对河南省经济空间集聚格局的经济增长效应的分析表明,总体上河南省县域间经济增长的空间相关性不显著。只有在高水平县域集聚区,县域经济增长与相邻县域呈显著的正相关关系,表现出区域之间的经济溢出效应。

This paper examines the evolution of spatial economic pattern in a typical less developed but fast growing province by using county as a spatial unit and per capita GDP as measuring index for the level of regional economic development. The result shows that the economy in Henan province appears in a process of spatial centralization, and the spatial economic structure supports notion of core-periphery suggested by regional economists. By using a spatial auto-correlation technique to compare the growth of per capita GDP in every county with its neighborhood counties, the one hundred and twenty seven counties in Henan Province were classified as four types （ HH, HL, LL, LH）. The spatial patterns of these kinds of counties were analyzed by diagrammatic representation. A linear regression model was then used to explain the effects of these patterns on economic growth. The result shows that, in Henan as s whole there is no prominent spatial correlation of economic growth between one county and its neighborhood counties. In other word, evidence does not support the spillover effects of economic growth between one county and its neighborhood counties. But within the agglomeration region of the province the spillover effects of economic growth between counties are evident.
