Evolution mechanism and simulation of urban logistics industry agglomeration area ecosystem based on CAS

The urban logistics industry agglomeration area ecosystem is an industrial ecosystem with such functions as self-organization, self-regulation and self-adaption. It is composed of enterprises and supporting institutions related to the city logistics industry chain. This paper analyzes the evolution mechanism of urban logistics industry agglomeration area ecosystem, and builds the evolution model by using the complex adaptive system (CAS) theory, and applies Netlogo software to simulate the process for getting the general evolution rule of urban logistics industry agglomeration area ecosystem. The proposed method can reveal the evolution rules and trends of urban logistics industry agglomeration area ecosystem and offer the accurate basis for making policy.
