摘要
本文基于环境规制视角,运用2006~2017年中国30个省份面板数据,探讨R&D投入强度对中国绿色创新效率的非线性关系及其在时间和空间上的差异性。结论显示:R&D投入强度对我国绿色创新效率的促进作用受限于环境规制水平,二者存在双重门槛,随着环境规制力度的加强,R&D投入强度对绿色创新效率的促进效果逐渐弱化,同时环境规制在时空分布上具有明显的差异性,因此引导当地政府采取适度环境规制对R&D投入强度驱动中国绿色创新效率有着重要作用。
Based on the perspective of environmental regulation,the panel data of 30 provinces in China from 2006 to 2017 are used to explore the nonlinear relationship between R&D input intensity and China's green innovation efficiency and its time and space differences.The conclusion shows that the promotion effect of R&D input intensity on China's green innovation efficiency is limited by the level of environmental regulation.There is a double threshold between the two.With the strengthening of environmen⁃tal regulation,the effect of R&D input intensity on the efficiency of green innovation is gradually weakened,and environmental reg⁃ulations have obvious differences in time and space distribution.Therefore,guiding local governments to adopt appropriate environ⁃mental regulation plays an important role in driving R&D investment intensity to drive China's green innovation efficiency.
