Mechanized agriculture uses energy for machinery, fertilizers, pestcides, electricity, and other management tools. Especially, after World War II, fossil fuel inputs on agriculture have increased rapidly in Japan. The increase of fossil fuel inputs causes not only the exhaustion of raw materials but the ecological diseconomy as to cultivated land. From this point of view, it is needed either to estimate the quantity of energy inputs or to analyze it in Japanese agriculture. The purpose of this paper is to estimate energy inputs requirement for factors of production in agriculture as the first step. The results (table 15) have not been done perfectly because of limitations of data. However, it gives the basic data for analysis of energy inputs on agricultural production. Therefore, it would be possible to estimate and analyze energy inputs for agricultural products by farms size and so on.本稿では,基本的に宇田川推計に依拠しながら「公表データ」を用い,農業生産のための各投入要素のエネルギー原単位及びエネルギー集中度の推計を行い,農業生産におけるエネルギー消費量の分析のための基礎データを整備することを目的としている.
