城市化对县域经济发展的影响——以云南省为例

Influences on county-level economy by urbanization:taking Yunnan Province for example

城市化与经济发展之间存在着密切的联系,但是两者间的影响机制却颇有争议,分歧主要源于数据差异,也与地理单元和空间密切相关。以云南省县域经济为研究对象,探讨了西部民族地区城市化与经济增长之间的关系。通过采用空间经济计量学的分析框架,构建了以城市和距离为基本因素的区域分类体系,并利用面板数据回归分析了城市化与经济发展之间的关系。分析表明,县域经济的增长与城市化之间存在着显著的正相关,但是在不同的县域,两者的关系有显著的差异;只有当城市化率达到21.5%,城市化才会显著促进经济增长;仅有昆明市及少数较大州级市及周边县域,它们的城市化才显著地促进了经济增长。

There is a close relation between urbaniza- tion and economic growth. However, there are disputes concerning affecting mechanism, which needs to be studied further. Part of the disputes come from data difference and relate to geographic unit and space. This essay focuses on county economy of Yunnan Province, tries to understand the relation between urbanization and economic growth at county level, especially for a western province with multi - nationalities. Within a framework of spatial econometrics, this essay constructs a regional classification based on cities and distance. Besides, it emphasizes on geographic features and location. Regression shows that there is a rather close relation between economic growth and urbanization, which depends on developing stages and locations. Only for those counties whose urbanization rates are over 21.5% , urbanization will promote economic growth distinctively. While only for those counties which are around Kunmin and some large cities, urbanization will definitely promote economic growth.
