多种环境规制工具对空气污染的异质性影响——基于地理探测器分析

Heterogeneous Effects of Various Environmental Regulation Instruments on Air Pollution:Based on Geodetector Analysis

基于2008—2018年中国105个环保重点城市数据,采用固定效应模型和地理探测器,探讨环境规制对城市空气质量的影响。研究发现,命令控制型环境规制在特定情境下有效,经济激励型规制持续有效且能显著减少空气污染,自愿型规制在2018年显著影响空气质量。此外,经济激励型与自愿型规制的交互作用对改善空气质量越来越重要。建议加强经济激励措施,提升公众环保意识,并制定适应地区特性的环境政策,以促进环境质量提升和可持续发展。

Based on the data from 105 key environmental cities in China from 2008 to 2018,the fixed-effect model and geodetector is used to explore the impact of environmental regulations on urban air quality.It is found that command-and-control environmental regulations are effective in specific contexts,while economic-incentive regulations are consistently effective and significantly reduce air pollution.Voluntary regulations significantly impacted air quality in 2018.Moreover,the interaction between economic-incentive and voluntary regulations is increasingly important for improving air quality.It is recommended to strengthen economic incentives,raise public environmental awareness,and develop environmental policies adapted to regional characteristics to promote environmental quality improvement and sustainable development.
