The Research Of The Spillover Effect Of The Innovative Activities Of Industry-university-institution In China

Innovative activities have a significant spillover effect.The spillover effect will contribute to sustained economic growth with the increasing of returns to scale.China's innovation shows a clear regional imbalance characteristic,while the R&D investment of industry-university-institution is also very uneven.On the basis of the above,this paper divides the spillover effect of the innovation into the spatial spillover effect and the spillover effect of the innovation subject according to the innovative value chain and studies the spillover effect of the innovative activities of industry-university-institution in the two modes of the spillover effect.Through combing,analyzing and summarizing the literature,according to the innovative theory,such as innovative value chain and triple helix theory,this paper estimates the R&D capital stock of industry-university-institution from 1998 to 2014 in China.At the same time,this paper analyzes the spillover effect of innovative activities of industry-university-institution with the R&D capital stock and the spatial econometrics models.The results show that there is the phenomenon of the regional imbalance and the imbalance of the innovation subject in China's provincial R&D capital stock.R&D investment in the eastern region is much higher than the Midwest.The R&D investment of large and medium-sized industrial enterprises is much higher than the universities and the research and development institutions.The R&D activities of industry-university-institution show a significant spatial spillover effect and this spillover effect is more pronounced in areas where economic development is similar.In the spillover effect of the innovation subject,the R&D investment of large and medium-sized industrial enterprises squeezes out of the R&D investment of universities and research and development institutions,resulting in "the competitive effect".There is a good synergistic effect in the R&D activities of universities and research and development institutions.
