国际技术溢出对我国绿色技术创新的影响研究

IMPACTS OF GLOBAL TECHNICAL OVERFLOW ON CHINA’S GREEN TECHNICAL INNOVATION

在当前经济新常态下,实现绿色发展,建设资源节约型和环境友好型社会,其关键在于促进绿色技术创新能力的提高,除了依靠国内自主研发之外,通过对外开放实现国际技术溢出效应也是中国提高自主创新能力的重要途径。选取17个国家地区作为我国的技术外溢国,以绿色专利申请作为绿色技术创新指标,利用2007—2017年中国省级面板数据,借助构造的空间杜宾模型检验国际技术溢出对我国绿色技术创新的影响。实证结果表明:中国省区环境技术创新之间存在显著的空间集聚特征,本地区的环境技术创新与地理相近地区的环境技术创新密切相关;进口贸易渠道的国际技术溢出对所在区域的绿色技术创新产生了显著的促进效应;双向FDI渠道的国际技术溢出对我国绿色技术创新具有负向作用;国内研发资本存量对绿色技术创新具有促进作用,且OFDI渠道的国际技术溢出与国内研发资本存量的交互作用显著促进了绿色技术创新。

Under the current economic situation,green development,resource-saving and environment-friendly society lies in increasing green technical innovation capacity,which relies upon internal self-search,and also upon openness to gain global technical overflow.This paper selects 17 nations as China’s technical overflow,taking green patent as green technical innovation indicators,employs China’s provincial panel data of 2007 to 2017 to establish a spatial Dubin model which serves to check the impacts of global technical overflow on China’s green technical innovation.China’s provincially environmental technical innovation is characterized by outstanding spatial clustering,with local closely related to its vicinity geographically.Global technical overflow from imported trading largely promotes the green technical innovation where the imported is.Global technical overflow from bidirectional FDI plays a negative role,but internal research capital stock does positively.Interaction between OFDI and internal research capital stock enhances the green technical innovation.
