环境规制能否促进海洋科技创新——基于我国沿海地区面板数据的门槛检验

Can Environmental Regulation Improve Marine Science and Technology Innovation:A threshold test based on coastal provincial panel data

为促进我国海洋环境保护和海洋科技创新的协调发展,本研究利用我国沿海地区的面板数据,检验环境规制与海洋科技创新的关系是否支持“波特假说”,进而采用门槛效应模型验证不同类型的环境规制对不同海洋科技创新变量的非线性影响,并提出发展建议。研究结果表明:“波特假说”在海洋领域更多适用于控制型环境规制与科技创新,其所强调的严苛环境保护政策对海洋科技创新的影响路径是增加海洋环境污染治理项目,进而强化海洋科技课题应用成果;未来应加强和规范海域使用金的征收和使用管理,不断优化海洋产业结构,以及科学选择环境规制工具和合理确定环境规制强度。

To promote the coordination between marine environmental protection and marine science and technology(S&T)innovations,this paper tested whether the relations of marine environmental regulation and marine S&T innovation supports the Porter Hypothesis based on the panel data of 11 coastal areas.Moreover,the threshold effect model was used to verify the nonlinear effects of different types of environmental regulations on different S&T innovation variables,by which many policy implications were put forward.The results showed that Porter Hypothesis was more suitable for controlling environmental regulations on marine S&T innovation,which relied on increasing marine pollution control projects,and further intensified the application results in marine S&T projects.It was necessary to improve the management of marine use fees,optimize marine industrial structure,and select environmental regulation tools and determine their use intensity scientifically.
