东北振兴以来吉林省区域经济差异的时空演变研究

基于吉林省2003~2015年间地区生产总值和人均地区生产总值数据,以市域、县域两个尺度单元为研究对象,采用人口加权变异系数、基尼系数、泰尔指数等统计分析方法,对吉林省东北振兴战略实施以来的13 a内,区域经济差异的时空演变进行定量分析,并运用泰尔指数的分解方法,探讨了吉林省区域经济差异的空间格局。结果发现：① 吉林省区域经济总体差异、市域差异、县域差异均呈逐年下降趋势。② 通过差异贡献率显示：县域差异是区域总体差异变化的主导力量,长春市域的内部差异远高于其他市域,但有逐年减小的趋势,长吉两地的二元结构仍然突出,是全省区域经济差异产生的主要来源,主导着全省区域经济差异走向;③ 从2003~2015年来看,全省经济增长速度较快的地区主要还是集中在“三核一带”;④吉林省经济差异主要是由资源禀赋、产业结构、极化效应和政策导向等多种因素综合作用的结果。

Regional Economic Disparities and Spatio-temporal Evolution in Jilin Province Since 2003

Based on the data of GDP and GDP per capita of Jilin Province from 2003 to 2015, the population weighting variation coefficient, Gini coefficient and Theil index are used to analyze the basic spatial units in the metropolitan and county regions. This article analyzes the temporal and spatial evolution of regional economic disparities in the 13 years since the implementation of the northeast revitalization strategy in Jilin Province, and discusses the spatial pattern of regional economic disparities in Jilin Province by using the decomposition method of the Theil index. The results show that: 1) the regional economic disparities in Jilin Province are declining year by year; 2) Theil index decomposition shows that: the county is the dominant force in regional overall disparities changes, the inner disparities of changchun city is far higher than other areas, but has a tendency to decrease year by year. The dual structure of Changchun-Jilin is still prominent, which is the main source of regional economic disparity, dominated the regional of the whole province to economic disparities; 3) From 2003 to 2015, the province's rapid economic growth is mainly concentrated in the “three nuclear zone”; 4) This article mainly from the resource endowment, industrial base, polarization effect and policy factors and other aspects, the preliminary discussion of the causes of regional economic disparities in Jilin Province.
