Description
研究成果の概要(和文):本研究では、自動車メーカー・部品サプライヤー間の取引関係の変遷を分析し、自動車部品(モノ)の取引の面では、着実に「オープン」な関係へと変化している一方、モノを生み出すベースとしての知識のネットワークの面では、かつてに比較すると「ややオープン」な関係へと変化したものの、依然として「クローズド」な関係が続いていることを明らかにした。また、こうした取引関係のあり方と当該部品サプライヤーの事業成果や企業成長との関係について調査・分析し、その背景にあるロジックを探った。研究成果の概要(英文):First, our research found that, in the Japanese automotive industry, the transaction pattern of components between automakers and suppliers is becoming more “open style” or “network style” since the 1990s, which means, Japanese automakers and their major suppliers tend to enlarge the scope of transaction bases. However, our research also found that Japanese automakers and their major suppliers were strengthening R&D-related ties, which means the business relationship between them are currently expanding to the earlier stages and are becoming tighter and closer with regards to R&D activities, at the same time. Second, our statistical analysis found that: for a supplier, (1) strengthening ties with its main customer automaker, (2) enlarging the scope of transaction bases, and (3) both strengthening ties with its main customer automaker and enlarging the scope of transaction bases at the same time, all leads to performance improvement.
