A Review of the Research on Supply Chain Relationships and Corporate Finance

The interaction between supply chain relationships and corporate finance has become a focal issue in academic and practical circles, especially under the dual drivers of globalization and marketization. This paper systematically reviews existing research on this topic, covering theoretical foundations from perspectives such as agency theory, stakeholder theory, and co-opetition game theory, which explain the nature of customer-supplier relationships. It also combs through empirical studies from four core angles: competition-cooperation, signal transmission, spillover effects, and information transfer, summarizing findings on how supply chain relationships impact corporate investment, financing, operations, and performance, as well as existing controversies. The aim is to clarify the research context, identify theoretical and empirical gaps, and provide theoretical support and direction for deepening future research on supply chain and corporate finance.
