Abstract：Based on the perspective of finace and taxation policy,this paper examines the impact of “innovation policy tool mix”and “innovation policy level mix”on enterprise R&D efficiency.Using China's gem and small and medium-sized board listed companies from 2008 to 2019 as research samples,data envelopment analysis is used to calculate enterprise R&D efficiency,and inverse probability weighted regression adjustment method is used to estimate the effect of innovation policy mix.The main conclusions are as follows.The innovation policy tool mix,the innovation policy level mix has a significant positive impact on enterprise R&D efficiency,and the policy “combination fist”has good complementary and synergistic effects.Compared with single policy tools and single level policies,the strong synergy of the innovation policy tool mix and the innovation policy level mix plays a more prominent and stable role in promoting R&D efficiency of enterprises.Compared with weak financing constrained enterprises,the innovation policy tool mix has a greater positive impact on the R&D efficiency of strong financing constrained enterprises.Compared with state-owned enterprises,the innovation policy tool mix,innovation policy level mix has a greater positive impact on the R&D efficiency of non-state-owned enterprises.
