知识产权保护与经济水平对技术创新的作用机制研究

Research on the Mechanism of Intellectual Property Protection and Economic Level on Technological Innovation

基于20122017年我国省级面板数据,将区域层面的工业企业创新过程划分为技术研发和技术成果转化两阶段,以地区规模以上工业企业为研究对象,采用混合OLS回归、固定效应模型和系统广义矩估计方法检验知识产权保护与经济水平对工业企业两阶段创新的作用。结果发现:①知识产权保护和经济水平对区域工业企业技术研发和技术成果转化两阶段均有显著促进作用;②在工业企业技术研发和技术成果转化两阶段均存在知识产权保护与经济水平的交互作用,这一交互作用削弱了两者对工业企业技术创新过程的促进作用;③知识产权保护、经济水平对工业企业技术研发阶段的影响强度大于技术成果转化阶段;④基于我国各地区当前经济水平,大部分区域仍须加强知识产权保护以进一步促进区域工业企业技术创新。

Based on the provincial panel data from 2012 to 2017,the industrial enterprise innovation process at the regional level is divided into two stages:technology research and development and technological achievement transformation.The industrial enterprises above the regional scale are taken as research objects,and mixed OLS regression,the fixed effect model and system generalized moment estimation are adopted.The method examines the role of intellectual property protection and economic level in the two innovation stages of industrial enterprise technology.The study found that:intellectual property protection and economic level have a significant role in promoting the technological R&D and technological achievements transformation of regional industrial enterprises.Second,there is a significant interaction of intellectual property protection and economic levels in both industrial technology R&D and technological achievement transformation.The interaction weakens the promotion of the technological innovation process of industrial enterprises.Third,the impact of intellectual property protection and economic level on the technological research and development stage of industrial enterprises is higher than that of technological achievements.Fourth,based on the current economic level of various regions in China,most regions Intellectual property rights protection must still be strengthened to further promote technological innovation in regional industrial enterprises.
