摘要
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。
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 tram - 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.
