초록

본 연구는 국내 주식시장에서 기업 고유의 위험(IVol)이 기업의 R&D 투자에 미치는 영향을 살펴보고, 이러한 영향력이 산업의 경쟁도와 업종의 특성에 따라 차이가 존재하는지를 검증하였다. 분석결과, 전반적으로 기업의 R&D 투자와 기업 고유의 위험 간에는 유의한 관련성이 존재하지 않는 것으로 나타났지만, 산업의 경쟁도와 기업규모, BM, 업력 등은 기업의 R&D 투자와 유의한 관련성이 존재함을 확인하였다. 또, 당기(t)의 기업의 연구개발투자비율은 전기(t-1) 연구개발투자비율에 유의한 영향을 받고 있는 것으로 나타났다. 표본을 업종의 특성에 따라 하이테크와 비하이테크 기업으로 구분하여 분석한 결과에서도 성장기회(BM)의경우에는 다소 차이가 존재하였고, 현금비율, 자기자본순이익률, 기업규모, 및 업력 등의 영향력 차이를 확인할수 있었다. 그리고 연구개발투자 비율의 변화율에 대하여 분석한 결과, IVOL이 증가할수록 R&D 투자의 변화율은 증가함을 알 수 있었고, 규모가 작은 기업일수록 R&D 투자비율의 변화율이 높은 것으로 나타나 산업 내경쟁이 치열할수록 기업의 R&D 투자비율의 변화율은 높아짐을 살펴볼 수 있었다.

Abstract

This study examines the effects of IVOL(Idiosyncratic Volatility) on firms' R&D investments in the domestic stock market, and verifies whether these influences differ according to industry competition and industry characteristics. As a result, there was no significant relationship between the company's R&D investment and the company's IVOL. Overall, however, the rate of R&D investment of firms was significantly influenced by the rate of R&D investment at t-1. According to the analysis of the sample divided into HighTech and Non-HighTech firms, there were some differences in the case of growth opportunities, and cash ratio, ROE, firm size, and firm history. As a result of analysis on the rate of change of R&D investment rate, it was found that the rate of change of R&D investment increased as the IVOL increased. As the competitive degree(HHI) increased, the rate of change in the R&D investment ratio increased.
