摘　　要：运用双重差分法(DID)和系统广义矩估计法(SYS-GMM)对西部环境规制的实施效果、减排机制和减排效应进行检验和识别。研究结论如下:(1)新环保法的实施有效降低了西部地区污染物排放强度,减排效果显著。(2)新环保法的减排作用主要通过城镇化水平、经济结构水平、科技投入强度和循环生产能力等4个机制变量发挥作用。(3)城镇化水平、科技投入强度、循环生产能力的减排效应较大,而经济结构水平的减排效应则较小。(4)西部地区污染排放强度具有明显的累积滞后效应。This paper comprehensively uses the difference-in-difference(DID)and the system generalized method of moments(SYS-GMM)estimation method to test and identify the implementation effect,emission reduction mechanism and emission reduction effect of environmental regulation in Western China.The conclusions are as follows:(1)The implementation of the new environmental protection law has effectively reduced the emission intensity of pollutants in the western region,and the emission reduction effect is significant.(2)The emission reduction effect of the new environmental protection Law mainly plays a role through four mechanism variables including the level of urbanization,the level of economic structure,the intensity of scientific and technological investment,the circular production capacity.(3)The level of urbanization,the intensity of scientific and technological investment,the circular production capacity have greater emission reduction effects,while the level of economic structure has less emission reduction effects.(4)The pollution emission intensity in the western region has obvious cumulative lag effect.
