Research on wastes from agricultural production based on the Input-Output Analysis

本研究尝试开发以农业生产活动为源头的垃圾种类和垃圾总重的估算方法。这是一项针对生产分析的“反问题方法”的研究。废物的产生过程在食品系统中是看不到的。这一过程是可以估计的，并澄清了在这些系统中能够建立废物工业的问题。通过本研究，可以提出在生产、销售和消费阶段有效减少浪费的想法。本研究提出了维护国家和地区高效良好环境的基本理念。基于投入产出分析的二氧化碳排放强度，有研究可供参考。本研究试图编制基于氮、磷的投入产出表，并在石川县进行应用。

This research tried the development of the method of estimating kinds of waste and gross weight of waste whose agricultural production activity is an origin. It is a research to aim at "method of a inverse-problems" of the production analysis.The production process of wastes is not seen in the food system. The process was able to be estimated, and the problem to which the waste industry was able to be established among these systems was clarified. The idea of proposal of an effective reduction of waste at stages of production and distribution and the consumption stage can be enabled by this research. This research proposed a basic concept of maintaining an efficient and good environment in the country and the region.Carbon dioxide emission intensity based on the Input-Output analysis, there was research that can be referred. This research try to develop Input-Output table based Nitrogen and Phosphorus, and apply Input-Output table in Ishikawa Prefecture.
