アジアのローカル・サプラヤーのものづくりイノベーション能力に関する実証研究

―中国サプライヤーの特性と評価を中心に―

抄録

This study is a comparative analysis of local automotive parts suppliers of China, Thailand and Japan, and an assessment of differences in their development pathways and capability building. Trailblazing studies on capability assessments of automotive parts suppliers were undertaken by Dr. Banri Asanuma (Asanuma, 1989, 1997). Characteristically, his research pays attention to suppliers’ product design capability, and the formularization of the development of suppliers through progress from works based on supplied drawings to those based on approved drawings.

As for the evaluation framework, we decided to introduce two new evaluation axes. The first is process design capability, which seeks cost reduction and quality improvement. The second is domain design capability, which diversifies the businesses of parts suppliers. In our study, we evaluate local second tier parts suppliers with three axes composed of Asanuma’s evaluation axis (product design capability), as well as additional two axes of process design capability and domain design capability.

We discuss the following in this paper. First, we outline preceding studies followed by our thesis. Second, we propose the analytical framework adopted in this study, and discuss the usefulness of the three evaluation axes covering product design capability, process design capability, and domain design capability for correctly assessing Asian local second tier parts suppliers. Third, we present the methodology of our study and the study results. Forth, the results of our evaluation with the above-mentioned three evaluation axes on parts suppliers in China, in comparison with Thailand and Japan are detailed respectively on a map and table. Finally, we give our evaluation results of Chinese Automotive Parts suppliers including a consideration of the background to commonalities and differences identified in the nationalities of suppliers. Also the study and references to outstanding issues are summarized.
