中国区域资源环境承载力的空间特征及收敛性分析

STUDY ON SPATIAL CHARACTERISTICS AND CONVERGENCE OF REGIONAL RESOURCES AND ENVIRONMENT CARRYING CAPACITY IN CHINA

在增强区域资源环境承载力的目标下,本文从社会承载水平、污染防治能力与生态修复潜力三个维度刻画了2011—2019年我国省域资源环境承载力,并利用Dagum基尼系数探究空间差异及来源,利用空间计量模型分析收敛状态。得出如下结论:(1)我国区域资源环境承载力存在绝对值“西强东弱”、增长率“西快东慢”的不均衡特征;(2)东西部间差异是四大板块资源环境承载力空间差距的主要来源,东部地区制约着整体资源环境承载力的提升;(3)中、西及东北部σ与β收敛趋势均强于东部地区,这使得东部地区资源环境承载力整体提升面临较大压力。

Based on entropy method,this paper uses panel data of 31 provinces in China(except Hong Kong,Macao and Taiwan)from 2011 to 2019 to describe resource and environmental carrying capacity from three dimensions of social carrying level(K1),pollution prevention capability(K2)and ecological restoration potential(K3),which is consistent with the goal of enhancing regional resources and environment carrying capacity.This paper also uses the Dagum Gini coefficient,kernel density estimation,and spatial econometric model to analyze spatial differences,dynamic feature and astringency of environmental bearing capacity of four regions in China which are east,west,middle,northeast parts.The spatial differences include withingroup variation,among groups variation and overall variation.The dynamic feature is described by Kernel density estimation,and astringency consists ofσconvergence andβconvergence,which is tested by Hausman,Wald,LM and LR model.It is concluded that:1)The carrying capacity of Western China is greater than that in Eastern China,while the capacity in Western China also develops more rapid.2)There are significant spatial differences in the resources and environment carrying capacity of these four regions,and the inter-group differences are the main sources.3)There are significant differences in the dynamic evolution process of the absolute difference of resource carrying capacity in the four plates.4)The characteristics ofσconvergence andβconvergence are different in the four tectonic plates.In Eastern China,there is noσconvergence in social carrying level,and there is noβconvergence in pollution prevention capability,which puts great pressure on overall improvement of resources and environment carrying capacity.
