中国经济发展的区域差异及其收敛机制检验

Regional Difference of China's Economic Development and Test of Its Convergence Mechanism

文章基于2000—2016年相关数据测度了中国30个省份的新克强指数,利用Dagum基尼系数对中国经济发展的区域差异进行再考察,并对经济发展的收敛机制进行了再检验。结果发现:中国经济发展总体区域差距呈现逐渐下降的趋势,但有一定的波动性;经济发展地区差距的主要来源为超变密度和区域间发展差距,但区域内发展不平衡将在长时间内制约我国经济发展;中国经济发展呈现出典型的σ收敛态势;经济整体上存在绝对β收敛,但不存在条件β收敛。

Based on the related data from 2000 to 2016, this paper firstly measures the new Keqiang index of China’s 30 provinces. And then the paper uses Dagum Gini coefficient method to re-examine the regional differences in China’s economic development and the convergence mechanism of economic development. The results turns out that the overall regional gap of China’s economic development shows a gradual-decline trend, but there is a certain fluctuation;the source of regional disparity in economic development mainly lies in intensity of transvariation and interregional disparity, but the unbalanced development within the region will restrict China’s economic development for a long time;China’s economic development shows a typical σ convergence trend;China’s economy has absolute β convergence, but there is no conditional β convergence.
