自主研发与知识积累:基于金融发展视角的门限模型研究

Independent Research and Accumulation of Knowledge:Research on the Threshold Model from the Perspective of Financial Development

已有研究表明自主研发与知识积累具有密切的联系。随着我国信贷资源的配置效率不断提高,研究金融发展在自主研发影响知识积累中的作用机理十分必要。本文使用我国2002-2009年省级面板数据构建非线性面板门限模型,以金融发展为门限变量,研究自主研发对知识积累的非线性影响及金融发展门限效应;在此基础上分析各省份金融发展变化作用于自主研发对知识积累影响的变化趋势。研究表明:高技术产业数量和非国有经济发展均对地区知识积累具有较大的促进作用,技术引进对地区知识积累则不会产生显著的影响,自主研发对知识积累的影响显著存在基于金融发展水平的"单门限效应";金融发展水平超过门限值后,自主研发对知识积累具有更大的促进效应;2008年以后,我国大部分省份跨过门限值进入高金融发展区域,自主研发对这些省份的知识积累都存在较高的促进效应。本文的研究有助于更好的理解金融发展与知识积累之间的关系,拓展了Ang(2011)对这一问题的研究外延,为政府部门制定相关政策提供了一定的参考基础。

Recent studies show that there are intimate connections between independent research and knowledge accumulation. With continuously improve of efficiency of credit allocative in China,it is necessary that analysis the impact of independent research on knowledge accumulation. The nonlinear panel data threshold model consisting of China＇s provincial panel data during 2002 and 2009 is constructed,and financial development is taken as the threshold variable, studing the nonlinear impact of independent research on knowledge accumulation and the threshold effect of financial development. On this basis, we analysis the trend of financial development is analyzed, which has an effect on the impact of independent research on knowledge accumulation. The results show. the effects of independent research on knowledge accumula- tion have a significant single threshold effect. When the degree of financial development exceeds the threshold value, the independent research has a bigger promotion effect on the knowledge accumulation. After 2008, most of the provinces in China cross the threshold value and reached the regional of the higher degree of financial development. Independent research has a bigger promote effect on the knowledge accumulation. A better understanding of the relationship between independent research and knowledge accumulation is provided, the extension of this problem by Ang expanded,and a reference for government departments formulate relevant policies is provided.
