基于EKC改进模型的福建经济与大气环境质量关系分析

基于福建省2011—2017年的经济数据和大气环境质量数据，选取人均GDP和二氧化硫排放量、氮氧化物排放量作为指标，通过改进的环境库兹涅茨曲线(EKC)进行拟合，研究福建省大气环境质量和经济增长的关系。结果表明:福建省人均GDP与大气污染物中二氧化硫排放量存在“倒U型”关系，且已经过顶部拐点；同时，随着人均GDP的增长，氮氧化物排放量呈现下降的趋势，说明福建省的大气环境质量随着经济增长而上升，验证了在一定阶段，经济增长与环境质量之间的正相关关系。福建省在控制及治理大气污染方面的措施较好，其对环境保护的重视及其产业结构特点，对其他省份的后续发展具有一定借鉴意义。

Economic Growth and Atmospheric Environment Quality in Fujian:An Improved EKC Study

This paper studied the relationship between environmental quality and economic growth based on data of economy and atmospheric environment quality from 2011 to 2017 using as indicators GDP per capita,sulfur dioxide emissions and nitrogen oxide emissions on the improved Environmental Kuznets Curve (EKC) model The results show that the relationship between economy and the second power of SO2 emissions is currently in the declining right half of the inverted U curve passing the apex of the curve,and the third power of nitrogen oxide emissions decrease with the increase of GDP per capita,indicating that the atmospheric environmental quality of Fujian Province increases with economic growth verifying the positive effect of economic growth on environmental conditions at a certain stageThis study presents good air pollution control and administration in Fujian due to its value on environment protection and special features of industries that helps the search for sustainable economic development in other parts of China
