摘　　要：为分析陕西省经济增长与环境污染特征关系,判断陕西省生态环保工作所处阶段,本研究基于EKC曲线对2004—2019年国家统计局发布数据中陕西省主要污染物排放量及人均GDP进行统计分析。结果表明,不同污染物的ECK曲线具有不同特征,其中化学需氧量、氨氮、SO_(2)排放量随经济增长呈先增长后减少的倒U型趋势,NO_x排放量随经济增长呈下降趋势。In order to study the relationship between economic growth and environmental pollution characteristics and determine the stage of ecological and environmental protection in Shaanxi Province,this study conducted a statistical analysis of the main pollutant emissions and per capita GDP in Shaanxi Province based on the EKC curve obtained the data released by the National Bureau of Statistics from 2004—2019.The results showed that the EKC curves of different pollutants had different characteristics,in which chemical oxygen demand,ammonia nitrogen and SO2 emissions increased first and then decreased with economic growth in an inverted U-shaped trend,and NOX emissions declined with economic growth.
