摘　　要：近年来,我国煤炭资源型城市在经济、社会和生态环境等方面的矛盾开始集中显现,研究其经济与环境之间的关系,对进一步推动煤炭资源型城市高质量发展,确保城市环境治理、生态保护与经济协调发展有重要意义。大同市是我国典型的煤炭资源型城市,根据2000—2017年相关数据,基于环境库兹涅茨曲线(EKC)及相关理论,研究大同市经济增长与环境污染的内在关联性。选取工业“三废”为环境指标,建立大同市EKC计量模型,进行拟合分析。分析结果表明:不同于典型的倒U型,大同市工业SO 2、工业废水和人均GDP曲线关系呈U型+倒U型,而工业烟粉尘、工业固体废弃物和人均GDP呈偏倒N型的弱倒U型曲线关系。大同市环境污染随经济的增长表现出先降低后升高再降低的趋势,目前大同市经济发展与环境正处于向好态势,但工业固体废弃物方面还有待进一步提升。In recent years,the contradiction of economic,social and ecological environment in coal resource-based cities in China has begun to appear.The relationship between economy and environment is studied to ensure that urban environmental governance,ecological protection and economic development are more coordinated,and further promote the high-quality development of coal resource-based cities.Datong city is a typical coal resource-based city in China.According to the relevant data of Datong city from 2000 to 2017,based on the Environmental Kuznets Curve(EKC)and related theories,the industrial“three wastes”are selected as the environmental indicators to establish the EKC measurement model of Datong city for fitting analysis.The results show that the EKC curve of per capita GDP and industrial“three wastes”in Datong city is different from the typical inverted“U”type.Industrial SO 2 and industrial wastewater show a“U+inverted U”curve relationship with per capita GDP,while industrial soot,industrial solid waste and per capita GDP show a weak“inverted U”curve relationship.With the economic growth,the environmental pollution of Datong city shows a trend of first decreasing,then increasing and then decreasing.At present,the economic development and environment of Datong city are in a positive trend,but the industrial solid waste needs to be further improved.
