공급-제조업체 지리적 근접성과 공급 사슬 계약이 공급업체 혁신에 미치는 영향

Geographic proximity between a supplier and a manufacturer has a significant impact on important decisions, such as new product development. This study considers a situation in which a manufacturer develops a new product in cooperation with the supplier who possesses core technology for the product and wants to enter a supply chain contract to encourage the supplier to invest in technology. We reflect supplier-manufacturer geographic proximity to the uncertainty of new product development time and examine its effects on the decisions of new product development and profits of the supplier and manufacturer under three supply chain contracts: a wholesale contract, a unilateral revenue sharing contract, and a cooperative revenue sharing contract. This study demonstrates that a short distance between the supplier and the manufacturer has a positive effect on the quality level and the price of the new product, resulting in improved profits for both parties. Furthermore, we examine how contract feasibility and the optimal contract can be determined by geographic proximity. We confirm that supplier-manufacturer geographic proximity has a significant impact on the decision-making for new product development, contract feasibility, and the optimal contract.
