《燃煤二氧化硫排放污染防治技术政策》绩效定量评估

基于全国46个城市(其中38个城市位于"两控区")1996~2005年的面板数据,运用difference-in-differ-ences(DID)模型对《燃煤二氧化硫排放污染防治技术政策》的绩效进行了定量评估。结果表明,该政策的实施对于降低工业二氧化硫排放量起到积极作用,使"两控区"城市年工业二氧化硫的排放量平均降低了19.3%。

Quantitative Evaluation of the Effectiveness of the Policy on Technologies for Prevention and Control of SO2 Emissions from Coal-Burning

Based on the panel data collected from 46 cities(including 38 cities located either in the SO2 Control Areas or in the Acid Rain Control Areas) between 1996 and 2005,a difference-in-differences(DID) model has been established to evaluate the effectiveness of the Policy on Technologies for Prevention and Control of SO2 Emissions from Coal-Burning.The result shows that the implementation of the Policy has posed positive effects on the reduction of the industrial SO2 emissions,resulting in 19.3% decrease of the annual average industrial SO2 emissions in the cities in the SO2 Control Areas and Acid Rain Control Areas.
