清洁生产技术创新、治污技术创新与环境规制

Clean Production Technology Innovation,Abatement Technology Innovation and Environmental Regulation

本文通过数理模型,证明了环境规制对技术创新的影响存在偏向性,在环境规制强度较弱阶段偏向于促进治污技术创新,而在较强阶段偏向于促进清洁生产技术创新。并利用中国2002-2015年省际面板数据,以清洁生产技术创新水平和治污技术创新水平的比值构建技术创新偏向指数。通过广义可行最小二乘法,估计面板固定效应模型,分析环境规制与技术创新偏向指数的关系,论证了本文的理论命题。另外,企业规模偏向于促进治污技术创新,而第二产业比重的上升、国有企业比例的增加和企业研究与开发支出则显著偏向于促进清洁生产技术创新。

This paper firstly proved theoretically that the environmental regulation was pollution abatement technology innovation biased at a weak intensity stage and clean production technology innovation biased in the strong intensity stage.Secondly,it proved the theoretical proposition above through a fixed effect model of panel data by means of FGLS based on the provincial panel data from year 2002 to 2015.Besides,the enterprise scale tended to promote pollution abatement technology innovation.But the increase in the proportion of secondary industrial,state-owned enterprises and R&D spending promoted clean production technology innovation significantly.
