【摘要】 为探究绿色信贷对制造业碳排放效率的影响，基于2007—2019年长江经济带沿线11个省(市)的面板数据，利用超效率SBM模型测算制造业碳排放效率，实证研究了绿色信贷对长江经济带制造业碳排放效率的影响。结果表明：绿色信贷对制造业碳排放效率具有正向影响，行业环境技术进步存在中介效应；通过门槛效应检验得出环境技术进步水平、绿色信贷强度在不同区间范围时，绿色信贷对制造业碳排放效率的影响程度不同；通过异质性分析得出地区层面下游地区绿色信贷能够有效推动制造业碳排放效率的提高，而中上游地区绿色信贷效果不显著，行业层面绿色信贷对五大高耗能制造行业碳排放效率的影响效果存在差异。因此，需完善绿色信贷的约束与激励机制，合理把控绿色信贷实施强度，积极推动制造业环境技术进步，实现制造业高效绿色发展。更多还原

【Abstract】 In order to explore the impact of green credit on the carbon emission efficiency of manufacturing industry, this paper implemented an empirical study on the impact of green credit on the carbon emission efficiency of manufacturing industry in the Yangtze River Economic Belt. The study is based on the panel data of 11 provinces and cities along the Yangtze River Economic Belt from 2007 to 2019, and using the super efficiency SBM model to measure the carbon emission efficiency of manufacturing industry.The results show that the green credit has a positive impact on the carbon emission efficiency of manufacturing industry, and there is an intermediary effect of industrial environmental technology progress. The threshold effect test shows that when the level of environmental technology progress and the intensity of green credit are in different ranges, the impact of green credit on the carbon emission efficiency of manufacturing industry is different. Through the heterogeneity analysis, it is concluded that at the regional level, green credit in the downstream region can effectively promote the efficiency of carbon emissions in manufacturing, while the effect of green credit in the middle and upper reaches is not significant. At the industry level, there are differences in the impact of green credit on the carbon emission efficiency of the five high energy consuming manufacturing industries. In the end, this paper suggest that it is necessary to implement green credit according to local and industrial conditions, reasonably control the implementation intensity of green credit, actively promote the technological progress of manufacturing industry, and promote the efficient and green development of manufacturing industry.更多还原
