The tendency of servicesation of economic development has become increasingly evident. The servicesation of industry and industrialization of service has become the development trend of the modern economy, which is the so-called trend of servitization. Service innovation has become an effective way to improve competitiveness for a large number of service enterprises and manufacturing enterprises. However, the current research on service innovation is mainly carried out in laissez-faire and piecemeal way. Therefore, under the background of servitization, research on innovative ways of service is very important. In this paper, we research on the composition of services innovation system in manufacturing enterprises and two available service innovative models for manufacturers, based on which, a detailed analysis of concrete content of these two service innovative models is made.
