In Korea, not only does the automobile industry account for a considerable share of the national economy, but since automobile production requires the installation and assembly of parts manufactured by numerous auto parts producers, the cooperative relationship between finished vehicle manufacturers and auto parts producers is of critical importance. Therefore, this study aimed to identify the types of cooperative relationships between finished vehicle manufacturers and auto parts producers in Korea's automobile industry and to examine whether these differ from the types of cooperative relationships in the United States and Japan. To this end, along with a theoretical review, questionnaires were distributed to managers in charge at three finished vehicle manufacturers, who responded regarding 133 auto parts producing companies. The data were analyzed using cluster analysis, factor analysis, and analysis of variance with PC SAS 6.12. The results showed that the control-type relationship was the most prevalent form of cooperative relationship. Additionally, supplementary analysis revealed that perceptions of price and information as measures of cooperative relationship performance differed depending on the finished vehicle manufacturer.
