中国省域绿色创新效率与绿色发展效率耦合协调研究

Research on Coupling Coordination between Green Innovation Efficiency and Green Development Efficiency of the Provinces in China

选取我国30个省域2009—2017年相关数据,利用DEA-SBM模型测算我国省域绿色创新与绿色发展效率,进行两系统耦合协调分析。研究表明,我国绿色发展效率整体较低,无效地区偏多,但绿色发展效率差异不断缩小并保持着不断提高的趋势;绿色创新效率整体偏高且相对稳定,绿色创新效率在波动中有缓慢上升的趋势;绿色创新效率与绿色发展效率整体存在较强的互动关系和较高的协调水平,且有增强的趋势,但还有较大提升空间。并据此提出针对性的对策建议。

Based on the panel data of 30 provinces in China from 2009 to 2017,we measure green innovation efficiency and green development efficiency of each province based on the SBM-Undesirable model,then calculate the coupling coordination of each province between green innovation efficiency and green development efficiency based on thecoupling coordination degree model,and finally analyze the regional differences and their trend.The result is as follows:In general,the green development efficiency is low in most provinces from 2009 to 2017,and the overall efficiency of green development is relatively low but the provinces’difference in green development efficiency is shrinking and the green development efficiency is constantly increasing during the period of sample survey;The overall efficiency of green innovation is relatively high and stable,the innovation efficiency is high in most provinces from 2009 to 2017,and the green innovation efficiency has a slowly rising trend in volatility;There is a strong interaction and high coordination level between green innovation efficiency and green development efficiency,The interaction and coordination level has an increasing trend,but there is still plenty of scope for improvement in the interaction.Therefore,specific policy recommendations were put forward to provide decision support for further promoting the coordinated development of green innovation and green development.
