Abstract: Opportunistic behavioral risks prevail in supply chain cooperation, but existing literatures are mainly based on the transaction cost theory, lacking the consideration of social relationships in supply chain. This paper made a deep analysis of the internal relationship between the structure, cognition and relationship dimension of social capital, and gave the path of social capital to suppress opportunistic behavior. Besides, it established the structural equation model of social capital, uncertainty and opportunistic behavior. Moreover, it tested the hypothesis of the model by collecting 300 valid questionnaires of supply chain members from different manufacturing industries, petrochemical industry, and other industries. The empirical research results show that information exchange in the dimension of social capital structure has a significantly positive correlation with cultural understanding and process integration, and there is a significant positive correlation between cultural understanding with trust and cooperation norms in the relational dimension. However, process integration has a significantly negative relationship with trust in the relational dimension but has a significantly positive relationship with cooperation norms. In the cognitive dimension, cultural understanding is negatively correlated with internal uncertainty to a large extent, while in the relational dimension, trust is negatively correlated with behavioral uncertainty. Uncertainty between members of the supply chain significantly increases the likelihood of opportunity behavior.
