Taking 15 RCEP member countries as the research objects,this article discusses the growth characteristics of a two-way direct investment network between RCEP member countries,the evolution process of their network resilience and their resilience pattern of national nodes.It uses the Exponential Random Graph Models(ERGM)to analyze the evolution effects of network resilience.The results show that:1)The growth of the two-way direct investment network between RCEP member countries is relatively stereoscopic and the characteristics of heterogeneity are significant.The complete and diverse composition of member countries is the endowment advantage of RCEP,which is the key to the evolution of the network resilience.2)The development of the overall investment network has obvious characteristics of adaptive evolution,which specifically shows the adaptive development process of restoring and developing by expanding the investment scale,adjusting and resisting by strengthening the synchronization of funds,and finally presents the network resilience structure of"strong core-loose edge".3)The"self-accelerating"effect of investment accumulation within the RCEP area,together with third-party effects,endogenously drives the evolution of the investment network resilience.Countries with competitive advantages such as open market,institutional environment,and labor quality have significant investment tendency,which is the main exogenous driving force for the evolution of investment resilience.In addition,national identity,tax burden differences and high-tech export differences as auxiliary exogenous driving forces play a role in the coordination of investment resilience.Bilateral trade agreement relationships and colonial historical relationships are positively coupled and embedded to influence the evolution of investment resilience,while inefficient investment relations that do not meet the requirements of economic development or fail to pass the test of international market will continue to be limited by geographical distance.
