摘要
运用逐步回归模型方法,探究影响地方政府环保投资规模的主要因素。研究表明:逐步回归分析法建立的数据模型具有很好的拟合效果,拟合度R2达0.806;同时得出地方财政收入、垃圾处理率、地区人口、人均公共绿地面积是影响地方环保投资的主要因素,其中效应最显著的是地方财政收入。据此,通过对影响因素分析提出了促进地方政府环保投资的对策建议:建立合理的地方环保激励机制以及加大中央财力支持可以缓解地方政府投资压力;多元环保投资体制建设可以为地方政府环保投资不足提供新的解决路径。
The main influencing factors of local government environmental investment scale were studied in the stepwise regression model. Results showed that the model had good fitting effect based on the stepwise regression method and the R2 reached 0.806. The influencing factors included the local revenue, waste disposal rate, population and per capita public green area. In the four factors, the most significant effect was the local revenue. Then, the countermeasure to promote local government investment scale could be proposed： establishing a reasonable local environmental incentive and increasing the central government financial support can ease the pressure of local government investment; multiple environmental investment mechanism can provide a new path to solve the lack of local government environmental investment.
