Abstract:With the development of the service-orientedSmanufacturing model, technology innovation capability and service capability are two important contents in the system of the enterprise"s core competence. This study found that: There are coupling relationship between the two; under the action of knowledge assets, the coupling relation is realized through the common knowledge base, common carrier of knowledge and the exchange of knowledge; the evaluation index system of technological innovation capability and service capability is constructed from the angle of input and output,Sand we used “three coefficient method” to calculate the coupling coordinative degree. This research provided a theoretical basis for the evaluation and regulation of the interaction between technology innovation capability and service capability.S
