In the automobile industry, the Japanese supplier system has been evaluated as one of the crucial factors which support the growth of the industry in history. Regarding the previous research of automotive parts suppliers, “Drawings supplied” and “Drawings Approved” features are recognized as one of standard methods which are used to evaluate the technological capability of suppliers. However, accompanied with the technological progresses, the advanced development phase for both auto-makers and their suppliers is becoming to be considered more and more important, and this phase is implemented ahead of yielding “the drawings”. Moreover, the supplier engaged in the advanced development phase may not be properly assessed based on the previous research. Thus, it is worth discussing the relationship between auto-makers and their suppliers on which focus the advanced development phase. This thesis uses the case study of Denso Germany and Denso Japan which present the No.1 Japanese automotive supplier, to analyze the contribution of Japanese supplier in the advanced development phase by transaction governance theory framework. In addition, it suggests the two possibilities for Japanese suppliers with plans to expand their business in China.
