海洋科技创新能力对海洋经济绿色全要素生产率的影响研究——基于我国沿海地区的实证分析

Research on the Influence of Marine Science and Technology Innovation Capability on Green Total Factor Productivity of Marine Economy:Empirical analysis based on China′s coastal areas

海洋科技创新能力对海洋经济绿色健康发展具有重要作用。文章采用2007—2016年沿海11个省(自治区、直辖市)面板数据,首先建立对海洋科技创新能力的综合评价体系,使用熵值-TOPSIS法对我国沿海11个省(自治区、直辖市)的海洋科技创新能力进行测算,再运用DEA-Malmquist法测算我国沿海11个省(自治区、直辖市)的海洋经济绿色全要素率,最后通过建立GMM模型研究海洋科技创新能力对海洋经济绿色全要素生产率的影响。结果表明:海洋科技创新对于海洋经济绿色全要素生产率具有显著促进作用,有助于海洋经济绿色持续发展,海洋经济绿色全要素生产率增长主要源于海洋经济绿色技术进步指数而非海洋经济绿色技术效率指数。

The innovation capability of marine science and technology plays an important role in the green and healthy development of marine economy.This paper adopted the panel data of 11 coastal provinces(autonomous regions,municipalities) from 2007 to 2016.Firstly,a comprehensive evaluation system for marine technology innovation capabilities was established,and the Weight-TOPSIS method was used to evaluate the marine technology of 11 coastal provinces(autonomous regions,municipalities) in China.Then the DEA-Malmquist method was used to calculate the green total factor rate of the marine economy in 11 coastal provinces(autonomous regions,municipalities).Finally,the influence of marine science and technology innovation ability on green total factor productivity of marine economy was studied by establishing GMM model.The results showed that scientific and technological innovation had a significant role in promoting the green total factor productivity of the marine economy,which was conducive to the sustainable development of the marine economy.
