流通业是连接生产与消费、保证社会经济顺利运转的中心环节。本文通过构建一个包含生产、消费与流通的三部门封闭经济系统，初步刻画其动态运行过程，分析了技术进步、生产技术系数及体制成本和垄断势力等参数变化对稳态均衡时各部门投入产出的影响。模型证明提高生产与流通部门的技术水平，降低商品流通损耗，不仅能够有效刺激消费，促进经济发展，还能在一定程度上抑制通货膨胀；而当前我国流通业中存在的体制成本与垄断加价则可能会挤占投资，抬高物价，降低劳动力工资实际购买力，减少社会产出，恶化贫富差距。

As the key link between production and consumption, circulation ensures smooth operation of social economy. In this paper, we construct a closed economic system with 3--sectors of production, consumption and circulation, portray its dynamic process initially, and analyze the effect of relevant parameters on equilibrium solution. The model shows that technical progress in production and circulation departments, as well as reducing the loss of commodity in circulation process, can not only promote economic growth, but also to some extent curb inflation. But institutional costs and monopoly pricing in circulation may crowd out investment, jack up prices, reduce the actual purchasing power of wages, depress the final output of society, and widen the gap between rich and poor.
