COVID－19 팬데믹 이후 고객집중도와 기업성과 간의 관련성

초록

[Purpose] This study examines the relationship between customer concentration (hereinafter CC) and firm performance after COVID－19. Furthermore, it verifies the moderating role of R&D in this relationship. [Methodology] CC is measured by 1) a dummy variable for companies with major customers; 2) the total sales proportion of major customers; and 3) the Herfindahl index based on sales. [Findings] The interaction term between CC and COVID exhibits a significant positive relationship, suggesting that maintaining cooperative relationships with existing supply chains appears to have mitigated the negative relationship between CC and firm performance. Moreover, these findings are only observed in the group with a higher level of R&D investment, supporting the inference that supplier firms with a higher propensity for R&D investment can strengthen their negotiating power based on superior technological capabilities. [Policy Implications] This study suggests that corporate managers need to consider strategies for R&D investment and the establishment of stable supply chains from a long term perspective.
