Venture capital,as an important source of financing for new energy start-ups,plays a significant role in the development of the new energy industry.Existing research lacks a multi-level discussion of the driving factors affecting venture capital in the new energy industry and has not deeply explored the formation mechanism of the new energy industry co-investment network.Therefore,taking China's new energy industry venture capital events from 2018 to 2023 as samples,a co-investment network is constructed.Based on the exponential random graph model,the formation mechanism of the new energy industry co-investment network is explored from three levels:individual,dyadic,and endogenous structure.The results show that venture capital institutions with state-owned backgrounds provide funds and policy support,high-reputation venture capital institutions attract high-quality project resources,and venture capital institutions with rich industry experience provide professional advice,all of which promote the formation of the co-investment network.Background homophily and regional homophily promote network formation,while experience homophily inhibits network formation.State-owned background homophily prompts venture capital institutions to form a joint force in terms of goals and strategies.Regional homophily promotes integration within industrial clusters.Experience homophily leads to strategy convergence and thinking limitations.Location embedding has a negative impact on network formation.The results provide a theoretical basis for venture capital institutions to select co-investment partners in the new energy industry and have reference value for the formulation of new energy industry venture capital policies.
