The correlations between services, service vendors and service platform, as well as environmental factors weave the service system into a complex ecosystem. Dynamic factors introduce continuous co-revolution to the system. Seeing the dynamic mechanism of service ecosystem is the premise of reforming and controlling the system. A research framework is proposed in this paper, which is built to explore what are the changes of services, which indicators can be used to evaluate the effects and how

... e dynamic factors are spread. We clarify the definition as well as structure of service ecosystem based on recent work. Then a stereo network model for service ecosystem is built. Also, the usual dynamic activities of services are presented and discussed, and then the most crucial indicators of service ecosystem are summarized. Finally, a research framework is built, and the relevancy of the dynamic activities, correlations and indicators is given.
