区域知识产权保护与绿色全要素生产率——基于空间杜宾模型的分析

Regional Intellectual Property Protection and Green Total Factor Productivity: Analysis Based on Spatial Durbin Model

摘要:

本文基于中国2004-2018年249个城市的面板数据,结合SBM模型测度的城市绿色全要素生产率指标,通过空间杜宾模型考察中国区域知识产权保护对绿色全要素生产率的直接效应与溢出效应,探讨该空间效应的异质性特征并揭示知识产权保护促进地区绿色发展的具体路径。本文发现,知识产权保护能够同时提升本地区和邻区绿色全要素生产率,且对邻区绿色发展的促进作用远高于本地；对位于东部地区、城市规模大以及交易市场正常运行的城市而言,知识产权保护的绿色发展促进效应更为显著；地区知识产权保护主要通过促进技术进步以达到提升地区绿色经济增长的效果。

Abstract:

Based on the balanced panel data of 249 cities in China from 2004 to 2018, combined with the green total factor productivity index measured by SBM model, this paper deeply investigates the direct effect and spillover effect of China"s regional intellectual property protection on green total factor productivity through Spatial Durbin model, and discusses the heterogeneity of this spatial effect in different regions, city scale and marketization degree. It also reveals the specific path of intellectual property protection to promote regional green development in the end. It’s found that Intellectual property protection can promote green total factor productivity in local and adjacent regions at the same time, and the promotion effect on green development in adjacent regions is even much higher than that in local regions, showing significant spatial spillover effect. For cities located in the eastern region, with large city scale and normal trading markets, the green development promotion effect of intellectual property protection is more significant, but for cities located in the western region and with small city scale, the spillover effect of intellectual property protection will worsen the green development of adjacent regions. Regional intellectual property protection mainly enhances technological progress to promote regional green economic development.
