The purpose of this paper is to empirically test the effect of family involvement on reducing the transaction costs of network in family firms, and to examine the mediating role of network structure in this relationship. Data were obtained from manufacturing family firms in Zhejing and Chongqing. The results indicate that family ownership and family commitment have positive effects on reducing the transaction costs of network, and the number of family generation leading the firm has a negative effect on reducing the transaction costs of network in family firms. The results also show centrality and density of network partially mediate the relationship between family commitment and reducing the transaction costs of network in family firms. The conclusions are significant for family firms in raising network organizational efficiency.
