Abstract: Six start-ups in underdeveloped areas are selected as the research object,and the rooted theoretical analysis method is adopted to explore the motivation and realization path of resource network reorganization of start-ups.The function mechanism of dynamic capability in the process of enterprise resource reorganization is analyzed from the three dimensions of perception,integration and utilization,and reconstruction.It is found that the initial resources established in the early stage of entrepreneurship cannot cope with the dynamic market environment,and enterprises are faced with entrepreneurial bottlenecks.The dynamic capability of the enterprise perceives this threat,and integrates and optimizes the initial resources by means of organizational fission,policy response,resource construction and expansion,and finally realizes the reorganization of the resource structure and the transformation of the resource path,forming secondary resources to enable enterprises to gain sustainable competitive advantage.The research helps to enrich the theory of resource constraints and dynamic capabilities,and provides some reference and inspiration for start-up enterprises on how to cultivate and use dynamic capabilities to solve the problem of resource constraints.

Key words: underdeveloped areas, start-ups, resource reorganization, dynamic capability, secondary resources
