广东省绿色经济发展的效率及影响因素研究

Research on Efficiency and Influencing Factors of Green Economy Development in Guangdong Province

为了加快广东经济的绿色转型,文章选取广东省2008—2018年21个地级市的面板数据,通过超效率SBM-GML模型测算广东省的绿色经济发展效率,然后采用固定效应模型探讨广东绿色经济发展效率的影响因素。结果表明:第一,广东省绿色经济发展效率趋势向好,但整体水平不高,大部分城市都处于无效率阶段,珠三角和粤东地区发展相对较好而粤北和粤西相对较差;第二,广东省的绿色生产率提升主要受益于技术进步,而技术效率、纯技术效率、规模效率的贡献不足;第三,人力资本水平、对外开放水平、环境规制、制造业与生产性服务业集聚都对广东省绿色全要素生产率有显著的正面影响,而第二产业占比则对绿色全要素生产率有负面影响。

In order to speed up the green transformation of Guangdong's economy,this paper selects panel data from 21 prefecture level cities in Guangdong province from 2008 to 2018,calculates the green economy development efficiency through the super efficiency SBM-GML model,and then uses the fixed effect model to discuss the influencing factors of green economy development efficiency.The results show that:first,the efficiency of green economy development in Guangdong province tends to be better,but the overall level is not high.Most cities are in the stage of ineffective rate.The Pearl River Delta and eastern Guangdong are relatively well developed while northern and western Guangdong are relatively poor;Secondly,the green productivity of Guangdong province is mainly benefited from technological progress,while the contribution of technical efficiency,pure technical efficiency and scale efficiency is insufficient;Third,the level of human capital,the level of opening up,environmental regulations,and the agglomeration of manufacturing and productive services have a significant positive impact on green total factor productivity in Guangdong province,while the proportion of the secondary industry has a negative impact on green total factor productivity.
