我们使用线性规划模型计算了日本家庭的最优消费模式，并考虑了要最小化的不同环境负担。该模型定义了94个工业部门和94种商品。在减少环境负担方面，本研究考虑了能耗、co2排放、废弃物和nox排放。根据家庭对商品调整后最终需求的方向（增加或减少），将商品分为三类：(1)在减轻各种环境负担的所有情况下，商品的最优需求都应减少；（二）在任何情况下都应增加最优需求的商品；(3)最优需求取决于环境负担类型的商品。在最终需求可调节的63种商品中，1类商品47种，2类商品9种，3类商品7种。这项工作还从经济和环境属性的角度描述了每种商品的特征。
We calculated optimal consumption patterns of Japanese households using a linear programming model, taking into account the different environmental burdens to be minimized. Ninety-four industrial sectors and 94 commodities were defined in the model. In terms of environmental burdens to be minimized, this study considered energy consumption, CO2emission, waste, and NOxemission. According to the direction (increase or decrease) of adjusted final demand for a commodity in the household, commodities were classified into three types: (1) a commodity for which optimal demand should be decreased in all cases of reducing various environmental burdens; (2) a commodity whose optimal demand should be increased in all cases; and (3) a commodity whose optimal demand depends on the type of environmental burden. Among 63 commodities whose final demand was assumed to be adjustable, 47 were categorized as commodity type 1, nine were categorized as commodity type 2, and seven belonged to commodity type 3. This work also characterized each type of commodity from the viewpoint of economic and environmental properties.
