Abstract: In the process of transportation, express companies must use one or diversified express transportation modes which are important traffic capacity resource need be input. However, as a matter of fact, there are no express companies, which can completely internalize all the traffic capacity resources. That is to say, it is necessary for express companies to cooperate with specialized transportation enterprises with varied traffic capacity resources. Since abundant uncertainty exists in realistic social economic system and decision-making bodies are with bounded ration, there is no one and only rule or institutional arrangement for the transaction relationship between express companies and specialized transportation enterprise. This paper has used evolutionary game model to analyze the evolutionary process of interactive game between express companies and specialized transportation enterprise. After dynamic studying on the process in which the parties (numerous express companies and specialized transportation enterprises) carry out strategic choice and adjustment, we can get the dynamic evolutionary stable strategy for express companies and specialized transportation enterprise based on evolutionary game model, and find out the stable equilibrium point. In the end, we can know that cooperation game between express companies and specialized transportation enterprise would evolve in two dimensions: one is stock cooperation strategy and the other is contract cooperation strategy. Both are evolutionary stable strategy, which can be verified by the strategy choices of enterprises in our realistic economy.
