长三角石化产业碳排放效率评价及其影响因素

Evaluation of Carbon Emission Efficiency of Petrochemical Industry and Its Influencing Factors in the Yangtze River Delta

选择长三角石化产业相对集中的13市为研究对象,利用2010—2018年石化产业面板数据,运用超效率SBM模型测算产业碳排放效率,运用Tobit模型分析碳排放效率的影响因素,得出以下研究结论:第一,考察期内,长三角13市石化产业碳排放效率呈现波动变化趋势,并且城市间碳排放效率差异明显。第二,人均主营业务收入、城镇化率对碳排放效率均有显著的正向促进作用;能源消费强度、能源结构、要素禀赋结构与碳排放效率呈负相关;产业聚集对碳排放效率具有积极作用但影响不显著。基于上述结论,提出长三角石化产业应当通过推进产业技术创新、推动产业聚集、加强政府监督、制定差异化碳减排政策等措施提升碳排放效率。

Taking 13 cities where petrochemical industry clusters in the Yangtze River Delta as research objects,based on the panel data of petrochemical industry from 2010 to 2018,by using the super efficiency SBM model to evaluate the industrial carbon emission efficiency and Tobit model to analyze its influencing factors,it is found out that,first,during the period from 2010 to 2018,the carbon emission efficiency of petrochemical industry in the 13 cities shows a trend of fluctuation,and there are obvious differences in the carbon emission efficiency in these cities.Second,per capital prime operating revenue and the urbanization rate play a significant positive role in improving carbon emissions efficiency;energy consumption intensity,energy structure,and factor endowment structure have significant negative impacts on carbon emission efficiency;industrial agglomeration plays a positive but not significant role in carbon emission efficiency.Accordingly,carbon emission efficiency of petrochemical industry in the Yangtze River Delta should be improved by enhancing industrial technology innovation,promoting industrial agglomeration,strengthening government supervision and making differentiation carbon emission reduction policies,etc.
