Abstract: With the development of the incubation mechanism network, the network members in the incubation network are more abundant, and the trust itself is not enough to maintain the open network relationship. The effective operation of this traditional governance mechanism is regarded as an important supplement to the lack of trust in the construction of network relations. While, ignoring the construction basis of the network relationship heterogeneity - the overlap of technology, limited the explanatory power of existing hatching network governance related research conclusions on the incubation mechanism. This paper explores the conceptual model of contract and trust in the incubation network, and uses the questionnaire survey and the multivariate hierarchical regression model to verify the influence path of the different dimension contract on the trust of different dimensions, even the regulation of the technology overlap in the process. The research shows that contractual control has a positive effect on ability trust and behavior trust, with a positive moderating effect of technology overlap. Contractual coordination has a positive effect on behavior trust, but the moderating effect of technical overlap is not obvious.
