  • The purpose of this study was to investigate the economic effects of a flame retardant aluminum screen developed by a company Economic effects were analyzed in terms of micro and macro-economic aspects. In the macro-economic aspect, economic effects were analyzed under the assumptions that the total import volume of flame retardant aluminum screen was approximately $50m^2$ in 2015 and that possible import substitution rates were 100%, 80%, and 60%. Results showed economic values of 2.25 billion won (100% import substitution rates), 1.8 billion won (80% import substitution rates), and 1.35 billion won (60% import substitution rates). If existing farms which had been using imported flame retardant aluminum screen replaced it newly developed with the flame-retardant aluminum screen developed in this study at rates of 100%, 80%, and 60%, the farms could save 750 million won, 60 million won, and 45 million won, respectively. Furthermore, the social cost savings from fire prevention could be 1.184 billion won. In the micro-economic aspect, if a farm with a typical-size ($1,000m^2$) greenhouse growing red pepper wanted to install flame retardant aluminum screen instead of generic aluminum screen, the farm may only pay an additional cost of 720,000 won. In comparison, if the farm chose fire insurance instead of flame-retardant aluminum screen, then the farm would pay 21,000,000 won for fire insurance. The above results show that the economic effect of flame retardant aluminum screen developed by the company would be be very efficient compared to the imported one.

  • 본 논문은 한국의 원자력발전소 가동에 따른 온실가스 저감 기여도와 국민경제적 효과를 평가하였다. 한국의 2009년 원자력 발전량과 국가에너지기본계획에 의거한 추정 발전량에 온실가스 배출계수를 적용한 결과, 원자력발전이 온실가스 배출량의 저감과 전기요금의 인상억제, 화석연료의 수입대체 등에 긍정적으로 기여하고 있는 것으로 분석되었다. 향후 국가에너지의 안정적 경제적 조달과 기후변화에 대응하기 위하여 원자력발전의 비중이 확대될 필요가 있는 것으로 보인다.
