A study on the motivation of knowledge spillovers under the influence of high speed railway

摘要

In order to estimate the influence of high speed railway on the knowledge spillovers among different provinces, this paper defines the connotation of knowledge spillovers. According to the analysis framework of knowledge spillover, the SAR/SDM panel data model are established based on the spatial econometric model to analysis the spatial change of knowledge innovation process. The results proved the existence of knowledge spillovers, and analyzed the different motivation of spatial spillover. The main reason for the spatial spillover of knowledge innovation is the path dependence caused by the time lag effect. Based on the analysis of knowledge spillovers in knowledge innovation, it can be found that regional innovation tends to agglomeration under the spillover effect of high speed railway, while regional production tends to be dispersed.
