However, there is a certain disparity between the current mainstream research model and reality, which leads to a deviated result. This paper puts forward a definition of ＂transaction efficiency＂ based on essential transaction services and establishes a model of the middleman＇s specialized production decision of transaction services. The research result shows that （1） transaction efficiency plays an important role in improving the middleman＇s specialized production level, （2） only when the transaction efficiency is higher than a certain threshold will the distribution middleman appear, and （3） the degree of economic specialization, price of commodities and transaction services, and other associated factors also affect the evolution of e-commerce transaction systems.展开更多
