Abstract
This study was conducted to evaluate the technical efficiency of Annual Chestnut production in South Korea. In this study, technical efficiency is the maximum possible production for which a certain amount of costs is inputted. For analysis on the technical efficiency we used output-oriented BCC Model, and then we analyzed correlation among input costs, production, gross income, net income, and market price per unit in order to determine the cause of variation in the technical efficiency. As study materials, we used statistics for the forestry production costs for 7 years from 2008 to 2014. The study results showed that the maximum possible production and actual production in 2008, 2009, and 2010 were 1,568 kg, 1,745 kg, and 1,534 kg by hectares in the order which were the same values. Consequently, the technical efficiency of those was all evaluated as 1.00. On the other hand, actual production from 2011 to 2014 was 1,270 kg 1,047 kg, 1,258 kg, and 1,488 kg by hectares in the order and the maximum possible production was 1,524 kg, 1,467 kg, 1,635 kg, and 1,637 kg by hectares in the analysis. From those values, the technical efficiency was evaluated in the following order:0.83, 0.71, 0.75, 0.91. The lowest value of the technical efficiency was 0.71 in 2012, and the values of this increased gradually since 2013. It is indicated that the cause of variation in the technical efficiency was related to the relationship between production and market price, and there was a negative correlation with r = -0.821 (p<0.05). The level of maximum available production per unit area was between 1,488kg in lower limit and 1,745 kg in upper limit, and the average was turned out as 1,548 kg.
본 연구는 우리나라 연도별 밤 생산량에 대하여 기술효율성을 평가하기 위한 목적으로 수행하였고 기술효율성은 일정량의 비용을 투입하여 얻을 수 있는 최대 생산가능량을 의미한다. 기술효율성 분석을 위하여 산출방향 BCC 모형을 이용하였고 기술효율성 증감의 원인을 분석하기 위하여 단위당 투입비용, 생산량, 조수입, 순수입, 시장가격등의 상관관계를 분석하였다. 연구자료는 2008년부터 2014년까지 7년간의 임산물생산비통계를 활용하였다. 연구결과, 2008년, 2009년, 2010년은 최대 생산가능량과 실제생산량이 ha당 1,568 kg, 1,745 kg, 1,534 kg로 동일하게 나타나 기술효율성이 모두 1.00로 평가되었다. 그러나 2011년부터 2014년까지는 실제생산량이 ha당 1,270 kg 1,047 kg, 1,258 kg, 1,488 kg이고 최대 생산가능량은 1,524 kg, 1,467 kg, 1,635 kg, 1,637 kg으로 분석되어 기술효율성이 0.83, 0.71, 0.75, 0.91로 평가되었다. 기술효율성은 2012년이 0.71로 가장 낮은 것으로 평가되었고 2013년부터 기술효율성 값이 점차 증가하는 것으로 나타났다. 기술효율성 증감의 요인은 생산량과 시장가격의 관계성이 있으며 r = -0.821 (p<0.05)로 부(-)의 상관관계를 가지는 것으로 나타났다. 그리고 단위 면적당 최대 생산가능량 수준은 하한 1,488 kg과 상한 1,745 kg사이에 있으며 평균 1,584 kg인 것으로 나타났다.
