Abstract
This study evaluated the economic value of the development of a new variety of Citrus unshiu using the income approach, Net Present Value (NPV), Internal Rate of Return (IRR), and Benefit/Cost (B/C) ratio. The new variety of Citrus unshiu was developed by the national institute of horticultural and herbal science in Korea, rural development administration. The technological evaluation of the development of a new variety of Citrus unshiu can be used to improve the efficiency and practicality of the development of a new variety of citrus. From the research results, the technological value of development of a new variety of Citrus unshui was evaluated at 109,455(discount rate=8%, minimum), 195,040(discount rate=4%, maximum), and 145,375(discount rate=6%, average) million won. The IRR was 51.4%, which was greater than the discount rate(4~8%). The NPV was evaluated at 145.3 billion won(discount rate=6%, average), 195.0 billion won(discount rate=4%, maximum) and 109.4 billion won(discount rate=8%, minimum), all of which were greater than 0. The B/C ratio was evaluated at 60.9(discount rate=6%, average), 81.3(discount rate=4%, maximum) and 46.1(discount rate=8%, minimum), all of which were greater than 1. Therefore, the economic validity of the development of a new variety of Citrus unshiu was identified by this technological evaluation.
본 연구의 목적은 농촌진흥청 국립원예특작과학원 감귤시험장이 2014년 최종선발을 마친 감귤(학명:Citrus unshiu) 하양조생(제감가-5호) 품종개발의 기술가치를 평가하는 것이다. 감귤신품종(하양조생) 개발의 기술가치 및 경제적 평가방법은 비용접근법(cost approach), 수익접근법((income approach), 시장접근법(market approach) 중에 수익접근법이 이용되었고, 순현재가치(NPV), 내부수익률(IRR), 편익/비용 비율(Benefit/Cost ratio)을 추정하였다. 이는 농업 R&D사업의 효율성과 실용성 제고를 위하여 이용될 수 있을 것이다. 분석결과에 따르면, 감귤신품종인 하양조생 개발에 따른 기술가치평가액은 할인율 수준에 따라 최소 1,094.5억 원(할인율 8%)에서 최대 1,950.4억 원(할인율 4%), 평균 1,453.8억 원(할인율 6%)으로 추정되었고, 내부수익율 IRR의 값은 51.4%로 본 연구에서 기본할인율로 이용된 6%(10년만기 국고채 할인율 3%와 리스크프리미엄 3%를 합친 것) 보다 매우 크고, 순현재가치(NPV)의 평균은 145,375백만원으로 영보다 훨씬 크며, B/C 비율도 최대(할인율 4%) 81.3에서 최소(할인율 8%) 46.1, 평균(할인율 6%) 60.9로 나타나 감귤 신품종 개발사업의 경제적 타당성은 매우 높은 것으로 평가된다.
