초록

본 논문에서는 국내 제조업을 대상으로 통합개념의 '비가격'의 신재생에너지 투입에 대한 기업의 최적화 행태를 분석하기 위하여 투입요소의 가격에 대한 정보없이 추정이 가능한 투입물거리함수를 추정한다. 신재생에너지의 연도별 암묵 (shadow) 가격을 도출하여 변화 패턴을 근거로 향후 신재생에너지의 잠재가격을 예측한다. 신재생에너지와 화석에너지 간 대체 가능성에 대한 측정 등 잠재 생산성에 영향을 줄 수 있는 제반 환경을 평가하고, 기술변화와 기술 효율성 변화의 Malmquist 생산성 지수를 계측하여 신재생에너지 투입의 생산성 지수에 대한 파급효과 여부 및 크기를 분석한다. 분석 결과, 1992-2012년 기간 동안 신재생에너지의 암묵가격은 매년 평균 17%씩 증가하는 것으로 나타났으며, 신재생에너지와 비재생에너지는 대체가능성이 상호 낮은 것으로 측정되었다. 신재생에너지 투입량을 1% 증가시키면 산업 생산성은 연평균 약 0.04% 감소하는 것으로 나타났다.
