Over the last twenty years, cooperation between M-department store and U-brand has diverged from the joint venture model involving a domestic enterprise and a multinational department store. Thus, this study adopted interview techniques to investigate the influence of the environment on organizational change from the perspectives of static transaction costs theory and the dynamic capabilities theory of an organization. Our results indicate that the relationship between environmental complexity and organizational change in the department store industry is largely influenced by the dynamic capabilities and control mechanisms. In other words, enterprises with stronger dynamic capabilities are better able to transform and reallocate their accumulated resources more effectively, thereby facilitating the implementation of new policies. The mutual trust among partners reduces the influence of the environment on organizational change.
