This paper studies the extent to which social capital drives performance in the Chinese venture capital market and explores the trend toward VC syndication in China. First, we propose a hybrid model based on syndicated social networks and the latent-variable model, which describes the social capital at venture capital firms and builds relationships between social capital and performance at VC firms. Then, we build three hypotheses about the relationships and test the hypotheses using our proposed model. Some numerical simulations are given to support the test results. Finally, we show that the correlations between social capital and financial performance at venture capital firms are weak in China and find that China's venture capital firms lack mature social capital links.
