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

摘要:

本文选取我国省域2009-1017年相关数据,利用DEA-SBM模型测算了我国省域绿色创新与绿色发展效率,进行了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。并据此提出了针对性的对策建议。

Abstract:

In the process of the promotion the supply-side structural reform and the implementation of the strategy of innovation-driven development, improving the green innovation efficiency is an important way to achieve green development. 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, and then calculate the coupling coordination of each province between green innovation efficiency and green development efficiency based on the coupling coordination degree model, and finally analyze the regional differences and their trend. The result is as follows: In general, the green development efficiency are low in most provinces from 2009 to 2017, and overall the 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 are 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 have 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.
