The work aims to discuss how to realize the process of service value co-creation and how to evaluate the results of co-creation in the context of service design and integrated innovation. From the perspective of customer engagement, according to different degrees of involvement, service co-creation behavior was divided into Participatory Co-creation of "jointly completing tasks", Engaged Co-creation of "establishing long-term relationships" and other co-creation types of "obtaining short-term friendship". At the same time, it was pointed out that Service Value Co-creation was diversified and complex, which could be carried out from three dimensions:cognitive, emotional and behavioral. It was recommended to evaluate the effect of service co-creation from two dimensions of intensity and time. The construction of "Type-Dimension-Effect" research framework for Service Value Co-creation has improved the theoretical basis of the delivery stage in service design, and provided a methodological basis for service designers to reduce the "uncertainty of service experience" through reasonable process and touchpiont design.
