Abstract:Due to the rapid development of mobile Internet and the fierce market competition, telecom operators begin to strengthen the cooperation of their telecom industry chain, and the Internet companies (such as SP/CP) and the terminal manufacturers are their important cooperative partners. The innovative cooperation models with SP/CP and terminal manufacturers are also the important directions of extending telecom industry chain. Through analyzing the cooperation motivation of telecom operators based on mobile Internet, three cooperation modes with SP/CP are proposed, which are the open platform, the equity investment and the strategic alliance. Besides, three cooperation modes with terminal manufacturers are also proposed, which are the cooperative contract, the further customization and the operators self-built. Then, we further separately present several selection strategies of cooperation mode to telecom operators, in order to provide reference for China's telecom operators to conduct cooperation in industry chain.
