Abstract:Under the background of mass entrepreneurship and innovation, in order to promote the advantages of venture capital and improve the technological innovation performance of startups, considering the influence of startups’ founding team, venture capital institutions’ characteristics and the technological connection between venture capital partners, based on the data of all the listed companies on the growth enterprise market (GEM) supported by venture capital from 2012 to 2019, this paper explores the mechanism of the influence on the startups’ technological innovation performance from the perspective of venture capital institutions’ equity proportion. The results show that venture capital institutions’ equity proportion negatively impacts on startups’ technological innovation performance, and there is no significant difference when it comes to different types of venture capital institutions, while the negative impact will be weakened when there is technological similarity or technological complementarity between venture capital partners. Therefore, in order to avoid negative impact caused by more shareholdings of venture capital institutions, the paper proposes countermeasures from the level of venture capital institutions, startups and the national level respectively, such as clearing positioning, grasping own control power and improving laws and regulations.
