中部六省碳排放效率与产业结构优化的耦合协调度及影响因素分析

采用SBM-Undesirable模型测算了1999—2017年中部六省的碳排放效率,分别计算了产业结构合理化指数和高级化指数,利用耦合协调模型考察了碳排放效率与产业结构优化的耦合协调度,并对其影响因素进行了实证分析。结果表明:中部六省碳排放效率和产业结构合理化的耦合协调度较低,处在中度失调和中度协调之间,碳排放效率和产业结构高级化的耦合协调度处在中度失调和中度协调之间,但有明显上升的趋势。人力资本、财政支出对中部六省碳排放效率和产业结构合理化的协调发展起到了促进作用,而环境规制、能源结构产生了抑制的作用。人力资本对碳排放效率和产业结构高级化的耦合协调度有正向作用,而外商投资、人均资本、制度质量和能源结构产生了抑制作用。

Coupling Coordination Degree of Carbon Emission Efficiency and Industrial Structure Optimization in Six Provinces of Central China and Research on Its Influencing Factors

SBM-Undesirable model is used to measure the carbon emission efficiency of six provinces in Central China from 1999 to 2017.The coupling coordination relationship between the carbon emission efficiency and rationalization and supererogation of industrial structure in central China is investigated by using the extended coupling model,and the influencing factors are analyzed.The results show that:The coupling degree of carbon emission efficiency and industrial rationalization is generally low,but there is a positive trend,and the coupling coordination degree of carbon emission efficiency and industrial supererogation is also low,but there is a significant upward trend.Through empirical analysis,it is found that human capital plays a significant role in promoting the coordinated development of carbon emission efficiency and industrial structure optimization,while energy structure plays a role in reducing.
