Abstract:

This paper studies on spatial spillover effect and its geographic boundary of explicit and implicit knowledge based on the perspective of geographic distance, using statistical data of Chinas 31 provinces from 2002 to 2012, and we get several finds. Firstly, there exists significant spatial spillover effect of explicit and implicit knowledge among the Chinese provinces, and spillover effect of explicit knowledge is greater than it of implicit knowledge. With increasing geographic distance, spillover effect of explicit and implicit knowledge all present downward trend, and spillover effect of explicit knowledge declines rapidly outside the range of 1 000 kilometers, spillover effect of implicit knowledge no longer exist outside the range of 1 100 kilometers. Compared with simply increasing R&D personnel and capital, promoting interaction of R&D personnel and optimization of capital structure is more useful for regional knowledge growth. Finally, conclusions and policy recommendations expressed herein.
