中国资源产业依赖的地区差异及演变——基于Dagum基尼系数分解

本文利用中国2003～2014年省际面板数据，结合Dagum基尼系数及其按子群分解方法与非参数估计方法，实证研究了中国资源产业依赖的地区差异及其动态演进过程。基尼系数测算及其分解结果表明，中国资源产业依赖在空间分布上具有明显的地区差异性，且其差异性呈波动下降态势，尽管超变密度的贡献率不断下降，但仍是地区差异的主要来源，地区间净值差距对地区差异贡献率不断上升，地区内差距贡献率较平稳。Kernel密度估计表明，中国资源产业依赖的地区差异经历了“先升后降”的变化过程。

Regional Disparities and the Evolution of the Dependence on Resource-based Industries in China---On Dagum Gini Coefficient Decomposition

Using China's provincial panel data from 2003 to 2014 , this article examines regional disparities and distributional dy-namics of the dependence on resource-based industries in China with Dagum's Gini coefficient and Kernel density estimation method . It reaches the following results . The dependence on resource -based industries in China is characterized by significant regional disparities . According to the overall Gini coefficient , regional disparities exhibits certain fluctuation . The intensity of trans -variation is the major source of overall inequality . The disparity among regions is on the rise , while the disparity in regions is relatively stable . Kernel density estimation indicates that the dependence on resource -based industries in China rises first and decreases afterwards .
