环境政策对绿色技术创新的影响研究——来自省级环境专利的证据

A Factor-influencing Analysis of Inducing Regional Technological Innovation——Evidence from Thirty One Provincial Environmental Patents

笔者运用2001年-2009年中国31个省级环境专利面板数据，通过非线性设定探讨了环境政策对绿色技术创新的影响。结果发现，环境政策总体上对绿色技术创新有显著的激励作用，这也支持了引致创新假说；知识水平对绿色技术创新有显著的正影响。我们还发现，环境政策对绿色技术创新影响具有动态性，因而，需要建立一种长效机制来促进绿色技术创新不断涌现。

Technology innovation, in particular green technology innovation, plays an important role in mitigating the conflicts between environment and economy. To test the induced innovation hypothesis, using China＇ s environmental patent panel data for the period of 2001 -2009, the paper explores the impact of environmental policy on environmentally-friendly technology with nonlinear methods, which not only investigates the effect of environmental policy on technological change, but also examines the effect of the existing knowledge on it. The results show that environmental policy significantly contributes to environmental innovation, which supports tile induced innovation hypothesis, and the existing knowledge has a significant positive impact on environmental innovation. It is also found that the impacts of environmental policies on the green technology innovation are dynamic. Thus certain long-run effective mechanism to be built to encourages green technology innovation to spring out continuously.
