    摘要:

    在经济发展过程中减少废气排放对环境的污染是我国在新时代亟待解决的难题。基于环境库兹涅茨曲线(EKC)理论,采用探索性空间数据分析方法和空间滞后模型对2005—2014年我国31个省市区的二氧化硫和烟尘排放进行分析,结果表明:我国的废气排放呈现出“高—高集聚”(东北地区和华北地区)和“低—低集聚”(西部地区)的空间自相关性;二氧化硫和烟尘排放分别与经济增长呈倒“N”型和倒“U”型曲线关系;影响废气排放的因素是多维而复杂的,且空间溢出效应显著;外商直接投资和人力资本的增加以及创新能力的提升对废气排放有显著的抑制作用,而工业化和城镇化以及人口密度的增加会加重空气污染程度。因此,政府应根据各地实际情况实施差异化的减排政策,各地区应协同治理环境污染;要鼓励创新,促进产业结构升级,并将新型工业化和城镇化与生态文明建设有机结合。

    Abstract:

    Emissions to the environmental pollution is an urgent problem to be solved in the new era of China. This paper uses the Exploratory Spatial Data Analysis method (ESDA) to carry out spatial autocorrelation analysis of the pollution emissions of sulfur dioxide and dust in 31 provinces and municipalities of China from 2005 to 2014, based on the basic model of EKC theory, and the use of spatial measurement model to explore the impact of China’s economic growth on emissions. From this productive analysis, we can find that:(1)the pollution emission of sulfur dioxide and dust in the provinces and municipalities of China shows the spatial autocorrelation of high-high aggregation in northeast region and Beijing-Tianjin-Hebei region and low-low aggregation in west region,(2)the emissions of sulfur dioxide and dust respectively with economic growth fall in “inverse N” type and “inverse U” type curve,(3)the improvement of innovation ability can improve the quality of atmosphere to a certain extent and the acceleration of the urbanization process will exacerbate the waste gas emissions. Combining with the research conclusion, this paper puts forward the following suggestions. Firstly, the government should establish a joint prevention and control mechanism of regional emission of sulfur dioxide and dust among the regions and fully realize the coordination development of economic and environmental pollution treatment, making differentiated strategy to reduce emissions, then, should consider the technological progress for the promotion of emission reduction, the government should also encourage innovation, and effectively promote the upgrading of industrial structure, and finally, combine urbanization development with ecological environment construction.
