공급자의 기회주의와 자산특유성이 신제품 개발 성과에 미치는 영향: 공급사슬통합의 매개효과

Supply chain management is drawing attention as an important issue in academia and industry as supply of raw materials and parts is disrupted recently. Various previous studies have sought ways to maximize supply chain performance through supply chain integration between buyers and suppliers. However, existing studies focused on the relationship between supply chain integration and firm performance, and few studies looked at both opportunism and asset specificity of suppliers. Therefore, this study empirically analyzed the effects of sup- plier opportunism and asset specificity on new product development performance through supply chain integra- tion. The analysis results are as follows. Looking at the direct effects of supplier opportunism and asset specificity on supply chain integration and new product development performance, opportunism significantly reduced sup- ply chain integration but had no significant effect on new product development performance. Asset specificity significantly increased both supply chain integration and new product development performance. Supply chain integration was found to significantly improve new product development performance. In addition, the indirect effects of supplier opportunism and asset specificity on new product development performance through supply chain integration were analyzed. As a result, supply chain integration did not mediate the relationship between opportunism and new product development performance, but partially mediated the relationship between asset specificity and new product development performance. This study is differentiated from previous studies that focused on the buyer, a company leading the supply chain management, despite the importance of the role of the supplier in improving the performance of the sup- ply chain. In addition, it has theoretical implications of paying attention to the irrationality of suppliers and sup- porting the relational exchange theory. Lastly, this study has practical implications, suggesting that buyers should be encouraged to reduce the opportunism of suppliers and secure relationship-specific assets necessary for transactions with the company in order to improve the new product development performance.
