地理距离、法律制度临近与国际知识扩散模式

Geographic distance,legal institutional proximity and international knowledge diffusion

以41个国家对3个创新领先国的专利引用数据为基础,采用非线性混合回归模型研究知识扩散的地理比邻效应和制度临近模式。研究结果表明:国际知识溢出不仅具有地理比邻特征,且法律起源制度具有制度临近效应,具有相同的法律起源的国家之间具有更高的知识扩散强度;而知识产权保护的制度临近对知识溢出没有影响。进一步的研究还表明,地理因素和法律制度因素在知识扩散中不具有互补效应和替代效应,说明知识扩散所表现出的地理比邻和制度临近效应通过不同扩散机制展开,未来有必要对制度比邻的渠道开展进一步的深化研究。最后文章根据研究结果提出了相关政策建议。

Based on the patent citation data of forty- one countries from three innovative leading countries,this paper investigates the geographic location and institutional proximity mode of knowledge diffusion. The results show that the legal institutional proximity definitely exits except for geographic localization mode in international knowledge diffusion. The countries with same legal origin have higher knowledge diffusion strength than otherwise. But the IPR institutional difference has no effect on knowledge diffusion. No substitutability or complementary effect is found between geographic location and legal institutional proximity mode means that further attention should be paid on the research of the different mechanism or channel of two modes. Lastly,we discuss the policy implication of these findings in term of promoting international knowledge diffusion.
