Abstract:  The backgrounds, concepts, research status and methods of product service system (PSS) and service design (SD) are analyzed. PSS methods are presented according to three points including design thinking, system integration and system elements; SD methods are also revealed by three points including human-centered methods, user-experience and co-creation. The research shows that the differences between PSS and SD lie in concept, essence, purpose, stakeholder and value, etc. As an innovative business strategy, PSS gives integrated functions, optimizes system process and enhances enterprises’ competitiveness; SD is a human-centered integrated design method, which emphasizes interactive behavior and co-creation among stakeholders, and brings customers continuous service experience and value. Furthermore, PSS and SD can also learn from each other. That’s to say, taking user experience into consideration of PSS can help meet users’ requirement better while SD can learn the development method from PSS and implement its concept.
