摘要

Based on the panel data of Guangdong industrial enterprises from 2006 to 2013, this paper empirically studies the impact of public R & D subsidies on private R & D expenditure and the impact of the two on the innovation performance of enterprises by using random effects model and fixed effects model. The results show that public R & D subsidies can promote enterprises to carry out private R & D expenditure, and there is an obvious time lag. Using grouping studies, we found that low-level public R & D subsidies can en courage enterprises to increase their private R & D expenditure, but high-level public subsidies will crowd out part of private R & D expenditure. Finally, this paper divides the innovation performance of enterprises into the stage of knowledge output and the stage of marketization. In the knowledge output stage, public R & D subsidies and R & D staff input can significantly improve the innovation performance of enterprises; in the marketization stage, public R & D subsidies cannot promote the increase of new product income, while the private R & D expenditure of enterprises can significantly increase the income of new products.
