In the industry of venture capital, the majority of investments in startups are realized in the form of syndica tion by venture capitalists (VCs), which diversify thus their risk and maximize their profits. Corporations also invest in startups with VCs, but often for different reasons. They rather seek to acquire information on the marketable innovations or new tech nologies. Their growing weight (17% of total investment in venture capital in 2015, against 8% in 2010) puts the question of the determinants of their investments. So, we investigate how their relations with VCs and their relationships in syndication netwo rks influence their decisions of investment. Using data of corporate venture capital (CVC) investments by US corporations between 2001 and 2013, we analyze their expenditure of CVC following their position in syndication networks, and their financial resou rces. The GMM models used show that the annual amount of CVC expenditures of these companies depends on the number of their relations of co - financing and their cash - flows of the previous year, and also their preceding investments. On the other hand, their previous centrality in the networks of syndication is not significant, contrary to the social network theory, which stipulates that prior central positions in syndication networks significantly explain future network positions of corporate venture capitalists.
