Abstract:Corporate development resilience enables companies to grow against the trend on the basis of a certain immunity to turbulent environment. In the post-pandemic era and the VUCA(volatile, uncertain, complex, ambiguous) era, how to improve corporate development resilience without brittle fracture under frequent external pull pressure is a major difficulty in management. Based on social network theory and elastic risk theory,the mechanism of internal and external social capital of executive team on enterprise development resilience was constructed with the mediating role of psychological capital and risk-taking ability of team. The results of empirical study using 329 paired data obtained from the research of small and medium enterprises show that:①the internal and external social capital of the executive team have a significant positive impact on the development resilience of the enterprise.②Team psychological capital and risk-taking ability play a mediating role in the influence of internal and external social capital of executive team on firm development resilience.③Team psychological capital and risk-taking ability play a chain mediating role in the influence of both internal and external social capital of executive teams on the resilience of corporate development.
