采用分位数回归方法,分析了城市市容环境卫生公共投资对不同地区生活垃圾处置水平的作用。结果显示:城市市容环境卫生公共投资对城市市容环境卫生质量改善有显著正向作用,对于社会经济不发达地区,环境卫生改善效果明显;但整体而言,我国东中西部地区仍存较大差异。结合我国正在推行的供给侧改革,东部地区后续投入和政策倾向应向加强生活垃圾资源化方向发展,以资源化促进减量化;而中部地区亟需通过优化投入方向和投入结构来提高生活垃圾处置效率。
The quantile regression method was used to analyze the effect of public investment in urban environment and public sanitation on the disposal level of domestic waste in different regions. The results show that the public investment in urban environment and public health has a significant positive effect on the quality improvement of city appearance and environmental sanitation. For the underdeveloped areas, the environmental sanitation improvement effect is obvious. However, on the whole, the eastern, central and western regions still have big differences . Combined with the supply-side reform being implemented in our country, the follow-up investment and policy orientation in the eastern region should be directed towards strengthening the recycling of domestic waste and resource reduction to promote reduction. In the central region, it is imperative to improve domestic waste by optimizing investment direction and input structure Disposal efficiency.
