Data service has different economic characteristics from voice service.Firstly, production mode of data service is roundabout production, secondly, driving power of dataservice is economies of specialization, and finally, management method of data service is impersonalmanagement. In data service market, information asymmetry and barrier to entry determinetransaction efficiency and the specialization level of service providers indirectly. Therefore,operator should intervene in the market by offering trade service in order to promote development ofservice providers. Because of different quality of service providers, market structure of dataservice must be the state that trade platform built by operator and intermediary platform built byoperator coexists.展开更多
