摘要
基于2007—2017年专利密集型产业面板数据,运用GML指数模型测度专利密集型产业8个行业的绿色全要素生产率,并对其进行收敛性分析。研究发现,专利密集型产业绿色全要素生产率整体水平较高,与传统全要素生产率相比,“波特假说”初步显现;总体上,专利密集型产业绿色全要素生产率呈上升趋势,技术进步贡献最大,不同行业的绿色全要素生产率增长水平和动态趋势不尽相同;整体行业、强专利密集型行业和弱专利密集型行业绿色全要素生产率内部差距仍然较大,整体行业与强专利密集型行业趋向共同稳态和自身稳态收敛,弱专利密集型行业仅趋向自身稳态收敛;行业集中度、行业规模对行业整体和弱专利密集型行业绿色全要素生产率具有正向作用,研发投入对强专利密集型行业绿色全要素生产率具有显著正向作用。
Based on the panel data of patent intensive-industries from 2007 to 2017,the research utilizes GML index model to measure the green total factor productivity of 8 patent-intensive industries and analyses its convergence.The results show that:the overall level of green total factor productivity in patent-intensive industries is relatively high and comparing it with traditional total factor productivity proves that the"Porter Hypothesis"has emerged.The green total factor productivity of patent-intensive industries shows a growth trend on the whole,with the greatest contribution from technological progress.The growth level and dynamic trend of green total factor productivity in different industries are not the same.The internal gap of green total factor productivity in the whole industries,strong patent-intensive industries and weak patent-intensive industries is still large.The whole industries and strong patent-intensive industries tend to converge toward a common steady state and their own steady state,while weak patent-intensive industries only tend to converge toward their own steady state.Industry concentration and industry size have a positive effect on the convergence of the whole industries and weak patent-intensive industries.For strong patent-intensive industries,R&D investment is positively significant.
