초록
본 연구의 목적은 DEA 기법을 이용하여 48개 국가의 농산물을 대상으로 고정되었지만 배분가능한 투입물인 토지의 재배분 전과 재배분 후의 생산효율을 비교하고 토지의 재배분을 통한 생산량 증대의 가능성을 살펴보고자 함이다. 실증결과는 주어진 일정투입 자원 하에서 단지 고정투입물인 토지의 비효율적 배분을 개선할 경우 생산효율은 재배분 전보다 약 16% 포인트 개선 가능성을 보여준다. 4가지 농산물의 재배분전 생산효율성에서 가장 효율적인 국가는 오스트리아, 중국, 미국, 브라질, 터키 등 14개 국가였다. 34개 국가는 비효율적인 생산을 하고 있는 것으로 나타났고 이들 대부분 국가에서 그 정도의 차이는 있지만 토지의 재배분이 생산효율을 높일 수 있는 여지가 존재하였다.
Abstract
The purpose of this paper is to compare the production efficiencies before and after reallocation of the fixed but allocatable input, land using DEA(Data Envelopment Analysis) and to estimate the levels of improvement of agricultural outputs by reallocation of land among 4 crops in 48 countries. Empirical results show that when allocation of land among 4 crops given constant total land is improved, average production efficiency may be increased by 16 % point. The countries that are already efficient in production efficiency before reallocation of land are 14 countries including Austria, China, The Unite States, Brazil, and Turkey. 34 countries which appeared to be inefficient have a possibility to improve production efficiency by reallocation of land to some extent.
