昆明市县区收入差距的时空演进及其成因分析

Inter-county Income Gap of Spatio-temporal Evolution and Influence Factors in Kunming

以昆明市各县区为研究单位,对收入差距问题作了实证分析。采用统计法和建立绝对β-收敛模型测度了县区收入差距,描述其时序过程和空间演替特征;利用Theil指标法揭示区域差距的构成与来源,并运用回归法探讨其影响因素。结论证实,昆明市区域差异演进并没有偏离收敛性假说:县区收入差距以2003年为拐点呈阶段性律动,总体差距趋小而梯度间差距和城乡间差距深化,社会消费、储蓄、财政支出是其影响因素,而普遍认为有促进作用的市场因素在概念模型分析中却不显著。为此,发挥市场力量势在必行。

This paper takes Kunming as the background, analyzing the issue on county income gap. It used the statistical methods and adopted the absolute-convergence model to measure the county economic income gap, describing the spatial and temporal evolution characteristics. On this basis, Theil index method is used to reveal the composition of regional disparities and using the regression method to explore the influencing factors. Kunming＇ s development has been confirmed to be the convergence hypothesis： the income gap of Kunming county economy in 2003 as a knee was appeared periodic rhythm-the overall gap trends small, while the differences between the gradient and the gap between urban and rural are widened. Consumption, savings and financial expenditure are its factors, but generally accepted market factors are reflected in the analysis is not obvious. As a response, playing the role of market factors is proposed.
