Abstract
본 연구는 비모수추정 방법인 자료포락 기법을 이용하여 우리나라 표고버섯 재배 임가를 대상으로 경영효율성을 평가하였다. 조사자료는 2013년 3월부터 10월까지 실시한 '표고버섯 경영 표준진단표' 적용 결과 중에서 20개 임가의 투입요소와 산출요소를 대상으로 하였다. 그리고 DEA 기법중 CCR 모형과 BCC 모형을 이용하여 기술효율성, 순수기술효율성, 규모효율성을 분석하였고 비효율성 임가의 개선방안도 제시하였다. 추가적으로 주업과 겸업재배임가의 경영효율성을 비교 분석하였다. 연구결과, 표고버섯 재배 임가의 전체기술효율성은 평균 0.655로 나타나 전체적으로 비효율성이 높은 것으로 나타났고 비효율성의 원인은 순수기술효율성(0.830)보다는 규모효율성(0.747)에 있는 것으로 분석되었다. 효율성 값이 1인 표고버섯 재배임가는 DMU2, DMU5, DMU6, DMU8, DMU10, DMU15, DMU20으로 7개 임가로 나타났다. 그리고 DMU7 재배임가의 경영효율성 진단 결과, 투입요소 중 신규접종비와 조성비에서 준거집단과 비교해 볼 때 과도하게 투입되고 있는 것으로 분석되었다. 주업과 겸업임가의 효율성 비교 결과 겸업임가가 상대적으로 비효율성이 높은 것으로 나타났고 그 원인으로 규모효율성이 문제가 있는 것으로 파악되었다. This study was conducted to evaluate the management efficiency of oak mushroom farms in Korea using the Data Envelopment Analysis (DEA), which is one of the non-parametric estimation methods. The data that was analyzed in this study was from the result of 2013 survey entitled "Standard Diagnostic Table for Oak Mushroom Management", which was conducted from March 2012 to October 2012. This survey was based on the inputs and outputs of 20 oak mushroom farms. Specifically, this study analyzed the technical efficiency, pure-technical efficiency and scale efficiency using CCR and BCC model of the DEA methods. Furthermore, this study compares the management efficiency between the full time oak mushroom production farms and part time oak mushroom production farms. Results showed that mean value for the technical efficiency was 0.655 which is considered as inefficient in general. For the pure-technical efficiency and scale efficiency, the mean values were 0.830 and 0.747, respectively which showed that inefficiency in the management was observed in the mushroom farms. Results also showed that there were seven farms with a total efficiency of 1, namely Decision Making Unit(DMU)2, DMU5, DMU6, DMU8, DMU10, DMU15 and DMU20. The management efficiency of DMU7 specifically the inputs for production was analyzed and compared to DMU5 and DMU6 and results showed that the DMU7 had an excessive inoculation and site development cost. Lastly, it was also observed that the full time mushroom production farms were more efficient as compared to the part time mushroom farms because of the lower scale efficiency value or smaller area for mushroom production allotted in the part time farms.
