Abstract From the perspective of social network theory, this paper analyzes social network trust characteristics of Hightech virtual industrial cluster(HTVIC), constructs threedimensional structure model which could effect HTVIC social network trust relationships, takes the direct trust degree, indirect trust degree and trust perceived risk degree in three dimensions as the core to construct the overall operation framework for HTVIC social network trust mode. On this basis, this paper establishes HTVIC social network dynamic trust evaluation model, comprehensively considers the time decay, dishonesty punishment, recommendation trust and risk perception and other factors, fully and accurately depicts the dynamic, complexity and uncertainty of HTVIC social network trust relationship from various perspectives. Finally, it takes MapleSim as simulation platform to simulate the HTVIC social network trust mode and its dynamic trust evaluation model. The simulation results show that the this trust mode can constrain and curb the occurrence of HTVIC dishonesty malicious acts, and make good effect for selecting the potential partners and improving cooperation success rate.
