This paper examines the ‘certification’ of government venture capital (GVC) programs, disputes whether the Chinese government venture capital (CGVC) can promote target firms’financing through the ‘certification’ on target firms, and how the ‘certification’ work. Using a dataset of 87865 Chinese listed firms over 2008–2018, we confirmed that CGVC’s investment promotes target firms’ equity financing but inhibits corporate debt financing through the certification effect and CGVC’s reputation. Moreover, the high reputation of GVC and high market awareness could strength the ‘certification effect.’Simultaneously, the ‘certification effect’is only effective for early and late-stage firms and private-owned firms, and invalid for mature stage and state-owned firms.
