Abstract: Social capital provides a channel for information and improves managers’ ability to discover new opportunities. Existing literature has shown that the internal social capital within the top management team (TMT) has a positive impact on team performance, but the mechanism of the internal social capital of the TMT affecting decision performance within the TMT has not been clear. Based on the upper echelons theory and the social capital theory, a theoretical model of the relationship between social capital, transactive memory system, and decision performance in TMT was proposed from the perspective of cognitive process. The structural equation model based on 392 sample data shows that TMT relational social capital dimensions of trust, the cognitive social capital dimension of shared vision on decision quality and satisfaction have positive effects, but the direct effect of structural social capital dimension of network ties is not significant. The influence of TMT internal social capital dimensions on the transactive memory system is cognitive dimension of share vision, relational dimension of trust and structural dimension of network ties in order. The TMT transactive memory system has a significant positive influence on decision quality and satisfaction. The transactive memory system mediates the relationship between the decision quality and satisfaction of internal social capital of TMT.
