【摘要】 基于1997—2016年重庆市各区县的人均地区生产总值数据,采用Dagum基尼系数和核密度非参数估计方法实证考察了重庆市经济发展的空间差异及分布动态。结果发现:从相对差异来看,重庆市的区域经济差异较大,总体差异呈波动下降趋势,其中主要差异来源于区域间经济发展差异;从绝对差异来看,全市及各大片区的经济发展绝对差异呈现扩大趋势,大部分片区经济水平高的区县所占比重逐渐增加,主城片区存在两极分化现象。更多还原

【Abstract】 Based on Chongqing’s per capita GDP data from 1997 to 2016, this paper uses the methods of Dagum Gini coefficient and kernel density nonparametric estimation to empirically research the spatial disparities and distributional dynamic of economic development in Chongqing. The results show that the differences among regions are the main source of the overall differences. From the perspective of relative differences,Chongqing’s regional economic differences are large, and the overall differences show a fluctuating and declining trend, among which the main differences come from the regional economic differences. From the perspective of absolute differences, economic development of the municipality as a whole and various areas shows an expanding trend. The proportion of districts and counties with high economic level in most areas gradually increases, and polarization exists in the main urban areas. The research innovation lies in that the writers of the paper use Dagum gini coefficient and kernel density analysis to calculate regional economic differences in Chongqing to reflect regional differences and their sources and analyze the distributional dynamic evolutions.更多还原
