The Impact Of Foreign And Domestic In-license Of Technology On Innovation In Regions Of China

Patent licensing is a kind of effective technology transfer channels, and when the patents are traded between the provinces or countries, the knowledge and technology included in the patent information also flow between these regions, thus forming the knowledge flow network. The properties of the network will affect the innovation performance of the regions.The thesis sets the 31 provinces as the research object, adopting the network analysis method with the patent license data in China from 2002 to 2012, to explore the evolution of the knowledge flow network of patent license in China and analyze the difference between the provinces in patent license network. The results are as follows:(1)With the expansion of patent license, the overall structure of the patent license network changes from loose to intensive gradually, with less isolated nodes, richer network connections and stronger network ties;(2) Beijing, Guangdong, Jiangsu, Zhejiang, Shanghai are the most important provinces in the knowledge flow network of patent license. These provinces absorb and send a large number of patent licenses synchronously, at the same time, a mass of patent licenses are traded within the province. More importantly, these provinces play the role of broker.On the basis, the thesis makes use of statistical software---Stata and knowledge production function to analyze the effect of number and source(network attribute) of patent license on the innovation performance. The thesis sets different types of patent applications as dependent variables, and the results indicate that patent licensing has different effects on these innovation performance. In general,(1)the knowledge flows of patent license from domestic regions and foreign countries don’t have direct impact on promoting the applications of utility and invention, however with the moderating effect of R&D expense and human capital, the domestic patent license flow makes prominent effect on utility application;(2)As for the knowledge flow network of patent license, the foreign indegree promotes the outputs of utility and invention, and domestic indegree promotes the PCT applications.
