摘　　要：塑料污染作为环境治理难题,研究其对我国美丽乡村人居环境建设的影响有重要意义。选取2013~2020年八省面板数据,借助超效率DEA模型测度塑料污染治理对美丽乡村人居环境建设的绿色效率,建立门限回归模型,探讨塑料污染治理对其影响。八省绿色效率具有显著的区域异质性,多个省份未达到高效率。塑料污染治理对美丽乡村人居环境建设的绿色效率存在以垃圾处理资金投入为门槛变量的单一门槛效应,其影响在跨过门槛后由正向拉动转为负面抑制。Since the environmental management has been the common concern,it is of great significance to study the impact of plastic pollution on the construction of China′s beautiful rural living environment.This paper,selecting the panel data of eight provinces from 2013 to 2020,evaluates the green efficiency of plastic pollution control on the construction of a beautiful rural human settlements environment with the help of the super-efficiency DEA model,and builds the regression model of the threshold to explore the impact of plastic pollution control on it.The green efficiency of the eight provinces has significant regional heterogeneity,and several provinces have not achieved high efficiency;Plastic pollution control shows a single threshold effect on the green efficiency of the construction of beautiful rural human settlements,with the investment of garbage treatment funds as the threshold variable,and its impact,after crossing the threshold,changes from positive pull to negative inhibition.
