辽宁省环境污染与经济增长关系实证研究

An Empirical Study of the Relationship between Environmental Pollution and Economic Growth in Liaoning Province

选取辽宁省2002—2018年环境污染与经济增长相关数据,采用主成分分析法,建立EKC模型进行实证研究。研究结果表明:辽宁省环境污染与经济增长的EKC曲线呈"N"型,且该省环境污染总体呈上升态势;财政支出、研发投入以及绿化对其环境污染未起到治理作用;人口增长会给环境造成负担。对辽宁省的环境治理提出应加强创新、财政支出适当倾斜以及提高人们环保意识等建议。
