中国县域经济差距及其收敛性的实证研究

An Empirical Study on Economic Disparity and Convergence across China's Counties

以县域经济为研究对象,运用Theil系数、变异系数以及面板数据回归分析方法对中国县域经济差距及其收敛性问题进行实证研究。研究发现:中国县域经济差距自2004年以来有缩小的趋势,分区域看,东、中、西部县域经济具有不同的收敛特征;同时,中国县域经济间具有比省域经济更强的收敛性,这说明中国省域经济差异的主要来源不是县域经济间的差异,而在于城市经济间的差异。

Taking county-level economy as research object, the authors make an empmcat study on the economic disparity and convergence across China＇s counties by using Theil index, variation coefficient and panel data regression methods. Research shows that China＇s county-level economic disparity has been decreased since 2004, and county-level economy of eastern, middle and western China has different convergent characteristics. Meanwhile, China＇s county-level economy has stronger convergence than provincial-level economy. This proves that China＇s provincial economic differences are not mainly caused by county-level economic differences, but lies in economic disparity among cities.
