Enhancing the Relationship Performance of Supply Chain Participants: Perspective of Interactional Justice

Abstract

Given the dynamic reorganization observed in erstwhile supply chains, many scholars are developing optimal methods to efficiently operate supply chains. Against this background, this study assumed that the relationships of supply chain participants were a key element of supply chain performance and explored paths for relationship optimization. For the empirical analysis, a survey was conducted with employees working in supply chain-related jobs in South Korea. A total of 350 questionnaires were included in the analysis, and a structural equation model was used for hypothesis testing. The two dimensions of interactional justice, namely interpersonal justice and informational justice, were found to have a significant positive impact on the factors of the triangular theory of love. Hence, perceiving justice when transacting with counterparts within the supply chain is vital for enhancing levels of intimacy, passion, and commitment. While passion and commitment showed a significant positive influence on relationship performance, intimacy did not. These results reflect the current supply chain environment, indicating that an appropriate level of passion and commitment is necessary for members constructing a supply chain. This study demonstrates that behavioral science factors commonly observed in interpersonal relationships can also be explored in business relationships, thus highlighting its interdisciplinary relevance. The results have practical implications for companies considering supply chain relational dynamics.
