Abstract

This paper examines the relationship between ownership structure and the intensity of R&D expenditures of a firm by analyzing the panel data composed of 553 manufacturing firms in KSE(Korea Stock Exchange) and KOSDAQ listed firms for the period of 2007-2014. The major findings are as follows; (1) Regarding the relationship between CEO stockholding and R&D intensity, we find the inverted-U shape relationship in KOSDAQ firms, consistent with the theoretical discussion and empirical studies on U.S. firms. The result suggests that management stockholding reduces agency problem at the R&D margin. On the contrary, the insignificant result in KSE firms seems to be due to the scant stockholding of most 'non-owner' CEOs. (2) Regarding the relationship between the largest shareholder's portion and R&D intensity, KSE firms exhibit negatively significant relationship, suggesting the existence of serious agency problem between the largest shareholder and the minor shareholders. This agency problem seems to be alleviated in KOSDAQ firms mainly because the founders with technology expertise are still in charge of the business. (3) Foreign investors seem to fail in effectively encouraging R&D expenditures in either KSE or KOSDAQ listed firms. This study contributes to the existing literature by showing for the first time that ownership structure affects R&D activities in different ways between KSE and KOSDAQ firms.

이 연구는 대표이사, 최대주주, 외국인의 지분율 변화가 R&D 지출 강도에 어떤 영향을 미치는지에 대해, 2007년부터 2014년까지 유가증권 및 코스닥 시장에 상장된 553개 제조업체를 대상으로 패널 분석을 실시하였다. 그 결과, (1) 대표이사 지분율과 R&D 지출간의 관계에 대해서, 코스닥 기업에서는 역-U자형 관계가 있음을 확인하였다. 이러한 비선형 관계는 이론 연구나 미국 기업에 대한 실증 연구들과 합치하며, 경영자 주식소유가 R&D 관련 대리인 비용을 줄이는데 일정 부분 기여함을 보여준다. 한편 최대주주가 아닌 대표이사가 의미 있는 수준의 주식을 보유하는 경우가 드문 유가증권시장 기업에서는 유의한 관계를 발견하지 못했다. (2) 최대주주 지분율과 R&D 지출간의 관계에 대해서는, 유가증권시장 기업에서 음(-)의 상관관계를 발견하였는데 이는 최대주주가 R&D 활동에 제대로 영향력을 행사하지 못하거나, 최대주주와 외부 주주간의 대리인 문제 때문으로 판단된다. 코스닥 기업에서는 최대주주가 R&D에 부정적 영향을 미치지 않는 것으로 나타났는데, 전문성을 가진 창업자가 경영 일선에서 활동하는 경우가 많아서 이러한 대리인 문제가 덜 일어나기 때문으로 보인다. (3) 외국인 지분율과 R&D 지출 강도 사이에는 두 시장 모두 유의미한 관계를 확인하지 못했다. 본 연구는 소유구조가 R&D 활동에 미치는 영향 면에서 유가증권시장과 코스닥 기업들 간에 뚜렷한 차이가 있음을 처음으로 보이고, 이를 이론적으로 설명하였다는 점에서 기존 연구와 차별성이 있다.
