Since Numerous enterprises exist in the mobile commerce value chain, it is beneficial for the value chain to conduct a reasonable profit-sharing mechanism. Based on the value-added mobile service, we study the coordination mechanism between mobile network operator and content/service provider, establish a two-stage supply chain optimization model and make some corresponding analysis. Our study shows that under certain conditions, strategies deducing from our model can achieve the coordination among and the profit maximization of the members of the main mobile commerce value chain. Finally, effectiveness of the model is validated by a numerical example.
