With the world stepping into the post-industrial era in which science and technology is developing rapidly, Service economy and service knowledgefication will construct the main characteristics of economy development in the future, and the development of service industry will also be the main content of economy development all over the world. During the 11th five-year plan period, domestic service industry is entering a stage in that its development growth speeds up and the status rises up swiftly in national economy. Along with the vigorous development of service economy, customers set a higher request to service innovation. Service enterprises needs to consummate service product unceasingly, and provides more new service that meet consumers' need. All of that actuates enterprise to intensify efforts in service innovation, raise efficiency of service innovation and perfecting the institution of service innovation. Under this background, this paper discussed the research issue of benefit distribution among different subjects in the process of service innovation. The paper is supported by the project of national natural science fund"Model and operation management of service innovation with multi-subject".Service innovation occurs frequently in service business. Managers, employees, customers and suppliers all play important roles in the process of service innovation, and to improve the positivity of all the subjects is important insurance for success of service innovation. In other words, division of powers, effect assessment and benefit distribution in service innovation are the main influencing factors of service innovation efficiency and effectiveness. Common interests are fundamental to maintain the service innovation system, and benefit gaining and contribution are in separable to the subjects in service innovation. Only if every subject can gain interest accord with its own expectation, will it participate in service innovation positively, and the satisfactory results were achieved in service innovation. So, the problem of benefit distribution had been a major concern for every subject of service innovation. The existed research related to innovation benefit distribution launch the discussions mostly from the technical innovation of view, while few discuss the problem from the viewpoint of service innovation. This paper did a deep research on the problem from the viewpoint of service innovation, and attempts to provide some suggestion for perfection about service innovation.Based on the review of domestic and foreign pertinent literatures, this paper has a deep research on the principle of benefit distribution in service innovation and summarized the mechanism of it. And combined with the theories of cooperative games, analytic hierarchy process (AHP) and fuzzy comprehensive assessment (FCE), a benefit distribution model was introduced. The chief contents in this paper include the following items: Firstly, the definition of the service innovation with multi-subject and a Conceptual model of service innovation subjects have been given, and the interactive relationship between innovation subjects are analyzed. Then, this paper analyzed the main characteristics of benefit distribution in service innovation, and the principles, influence factors and methods of benefit distribution was analyzed and discussed. Finally, based on cooperative games theory, the benefit distribution model in service innovation was presented. |
