摘要 以2012-2019年我国民营上市公司数据为样本,运用双重差分法对第二批科技金融结合试点政策是否对企业研发投入产生显著影响进行实证研究,并进行异质性分析。研究结果表明:第二批科技金融结合试点政策对民营上市公司的研发投入具有显著的抑制效应;我国东部地区、省会城市和科教水平较高的试点城市对于企业研发投入的负向影响更加显著。 Using the data of private listed companies from 2012 to 2019 as a sample,this paper empirically investigates whether the second batch of pilot policies for combining science and technology with finance has a significant impact on the R&D investment of enterprises by using differences-in-differences method and conducts heterogeneity analysis.The results of the study showthat the second batch of science and technology financial combination pilot policies have a significant inhibitory effect on the R&D investment of private listed companies,and the PSM-DID robustness test supports the above findings.The heterogeneity analysis shows that the negative effect of the pilot cities with higher level of science and education in the eastern region,provincial capitals and pilot cities with higher level of science and education on the R&D investment of enterprises is more significant.
