Abstract: Faced with the dual dilemma of environmental uncertainty and new disadvantages, start-ups join the entrepreneurial ecosystem and build the network relationships with other actors to conduct bricolage on the complementary resources such as knowledge, information and technology, so as to survive and grow. However, how to comprehensively use the network relationships in the ecosystem to promote the network bricolage activities to build competitive advantage quickly and flexibly has not been well answered. The existing studies mainly focus on the concept definition and function of network bricolage. The research on the types and theoretical connotation of deconstruction network bricolage is insufficient, and there is a lack of analysis of its effect and large sample empirical test.

Key words: ambidexterous network bricolage, absorptive capacity, new venture performance, entrepreneurial ecosystem
