Abstract

In the relationship between the shareholding ratio of National Pension Service (NPS) and the investee firm's value, this study examined the mediating effect of R&D expenditure which its increase can indirectly induce the increase of firm value, and examined the moderated mediation effect of the Stewardship Code implementation which pressures investee firms' to increase R&D expenditure and firm value. Using the Korean listed companies' data from 2016 to 2021, the analysis showed that the R&D expenditure had a partial mediation effect on the relationship between NPS's shareholding ratio and firm value. Also, the analysis showed that the NPS's Stewardship Code implementation had positive moderating effects on following relationships, one between NPS's shareholding ratio and R&D expenditure, and the other between NPS's shareholding ratio and firm value. In all, on the relationship between NPS's shareholding ratio and firm value, the R&D expenditure's mediation effect differs before and after the implementation of the stewardship code, which shows the moderated mediation effect.

본 연구는 국민연금의 소유지분비율과 투자대상기업의 기업가치 간 관계에서, 투자대상기업이 R&D 투자를 늘리도록 독려하여 기업가치의 제고를 간접적으로 꾀할 수 있을 것으로 판단하여 R&D 투자 정도의 매개효과를 분석하였고, 2018년 7월 스튜어드십 코드의 도입에 따라 투자대상회사에 대한 R&D 투자 및 기업가치 향상 압박이 도입 전에 비해 더 커졌을 것으로 판단하여 위 매개효과에 스튜어드십 코드 도입이 미칠 조절효과를 분석하였다. 2016년부터 2021년까지의 한국 상장회사 자료들을 활용하여 분석한 결과, 국민연금의 소유지분비율과 기업가치 간 관계에서 R&D 투자의 부분적 매개효과가 존재하고, 국민연금의 스튜어드십 코드 도입은 소유지분비율과 R&D 투자와의 관계, 소유지분비율과 기업가치와의 관계를 모두 강화시켜 조절효과가 존재함을 확인했다. 이는 국민연금의 스튜어드십 코드 도입 전후에 따라 소유지분비율과 기업가치 간 관계에서 R&D 투자 정도의 매개효과가 달라지는, 조절된 매개효과가 존재하는 것으로 나타났다.
