Abstract: Service Modular Value network is a special forms of network organization. Through the case comparison, explored the difference of the node, linear and Interface of the service modular value network of cigarette industry and food manufacturing industry. The research found that due to the industrial environment and industrial attribute difference, there are obvious differences between the two industries in the value module node activity, the linear connection and the interface rule design. The result shows that, Service modularity can promote the industrial value network service customized demand, reduce the value of the value network to achieve cost, industrial environment and attributes can affect the design of industrial value network service module. According to the industrial practice, through the design of the node cohesion of the value module, the loose coupling design, interface components and interface design and adjust process of interface design, can improve the value creation level of the industrial service module value network.
