英文摘要：

These days supplier management is getting more and more important for large manufacturers in such technology-intensive industries as automobile, electronics, telecommunication, aerospace and computer as their product life cycles get much shortened. One big trend of supplier management for manufacturers in these industries is to involve their suppliers in their secretive new product development processes. With the advance of economic globalization, China is gradually becoming the world＇s largest ＂factory＂, how to improve the manufacturing self-determined innovation capability becomes the top priority of China＇s equipment manufacturers development. Therefore, according to China＇s manufacturing enterprises, the study of the relations between supplier involvement in new product development （SINPD） and the equipment manufacturers＇ self-determined innovation capability has an important theoretical value. Taking equipment manufacturing enterprises for example, the relationship between SINPD and the equipment manufacturers＇ self-determined innovation capability is explored in this article. The conceptual model including SINPD, relationship interactions, knowledge creation, self-determined innovation capability is constructed, and the theoretical hypothesis are given. Through questionnaire survey, data processing, model checking, and ulti- mately arrived at the conclusion of the study. Through SEM test, it indicates that SINPD has significant positive effects on both relationship interaction and knowledge creation, and then through them has significant positive effects on the enterprises＇ self-determined innovation capability. Therefore, the equipment manufacturers should actively put in practice SINPD, strengthen the management of suppliers＇ evaluation and selection, and focus on the interaction with suppliers and knowledge creation. With suppliers＇ professional skills, knowledge or the advantage of ability, also its abundant resources, at the same time giving them the appropriate responsibility a
