摘要
基于DPSIR模型构造中国环境质量评价体系,通过熵值法对相应指标进行权重设计并计算我国30个省市2007-2016年的环境质量得分,结果表明整体上看,中国环境质量正逐步改善,但存在明显的时空异质性。从空间分布格局来看,中国环境质量南北差异较大,南部地区明显优于北部地区;就东中西三大经济带分布而言,中国环境质量呈现“两边高,中间低”的空间分布格局;从时空态势来看,2007-2016中国环境质量变化态势分为上升型、升降型、平稳型以及反L型。完成空间效应分解的结果,表明当地政府的环境规制不仅能够有效改善该地区环境质量得分,而且会产生明显的空间溢出效应,促进周边地区环境质量提升;当地经济发展水平、技术研发水平的提升能够促进环境质量改善,但会对周边地区环境质量改善产生抑制作用;当地产业结构的升级对该地环境质量改善具有明显的推动作用,而当地人口规模的增加会对环境质量产生抑制作用,但二者都对周围地区的辐射作用较低,对其环境质量水平没有明显影响。
This paper,based on the DPSIR model,is aimed to construct China’s environmental quality assessment system.The entropy method is employed to weight the corresponding indicators and calculate the environmental quality scores of 30 provinces and cities in China(2007-2016).The results show that 1)in general,China’s environmental quality has been improving,but there is obvious spatial and temporal heterogeneity;2)in terms of spatial distribution,the southern region enjoys obvious superiority to the northern;3)as for economic belts distribution,the three in East,Central and West,the quality falls into a pattern of“high on both sides and low in the middle”;4)from the perspective of time and space,the changes(2007-2016)bear a feature of rising,lifting,stationary and anti-L.The spatial effect decomposition shows that 1)the local government’s environmental regulation can not only improve the quality score,but also produce significant spatial spillover effects,thus a good influence on the surrounding areas;2)an improvement of local economy and technology research promotes environmental quality,but it will inhibit that of its neighbors;3)the upgrading of local industrial structure noticeably enhances the environmental quality,and the increase of local population will inhibit it;both have low radiation effects on the surrounding areas and have no significant impact on their environmental quality.
