Abstract Under transition economy situation, corporate social ties are considered to be an effective way to break through the institutional legitimacy limitation and resource constraints. Based on the Social Network Theory and Resource Constructivism Theory, this research will incorporate R&D ties as another important dimension of social ties, from the perspective of resources bricolage to study the relationship between corporate social ties and business model innovation. The results show that: ① business ties, political ties and R&D ties all have a significant positive effect on business model innovation;② business ties, political ties and R&D ties all have a significant positive effect on enterprise resources bricolage activity;③ resources bricolage plays a different role between corporate social ties and business model innovation. Specifically, resources bricolage works as a partial mediator between business ties, R&D ties s and business model innovation, and works as a full mediator between political ties and business model innovation.
