摘　　要：基于内生增长模型,构建包含银行信贷配置结构、政府环保支出和环境污染的理论框架,数值模拟结果表明,银行信贷配置倾向于民营企业会加剧环境污染,环保支出和环境质量之间存在非线性关系。在此基础上,利用中国省际面板数据进行空间计量检验,研究表明:省际环境污染及其影响因素间存在显著正向空间相关性;信贷配置结构倾向于民营企业不利于环境污染改善,政府环保支出和环境污染之间呈倒“U”型关系,与理论模型结果一致;引入交互项之后发现,信贷配置结构对于环境污染影响的边际效应与政府环保支出有关,两者呈非线性关系。加强民营企业环境污染监管,扩大政府环保支出以及区域协同环境治理对于环境质量改善具有重要意义。Based on the endogenous growth model,a theoretical model including bank credit allocation,government environmental expenditure and environmental factors is built.The numerical simulation results show that if private enterprises obtain more credit capital,it will increase environmental pollution.In addition,there is a nonlinear relationship between environmental expenditure and environmental quality.Furthermore,the study applies relevant spatial data from 31 provinces in China to a spatial econometric model.The results indicate that environmental pollution among provincial regions shows a significant positive spatial autocorrelation,credit allocation structure tends to private enterprises which is not conducive to the improvement of environmental pollution,and environmental expenditure and environmental pollution display an inverse U-shaped relationship,which supports the numerical simulation results.After introducing the interaction term,it is found that the marginal effect of the credit allocation structure on environmental pollution is related to the government's environmental protection expenditure,and the two have a non-linear relationship.Strengthening the environmental pollution supervision of private enterprises,expanding government expenditures on environmental protection and regional collaborative environmental governance are of great significance to the improvement of environmental quality.
