循环经济系统废弃物资源化的经济学分析

本文分析了废弃物资源化过程和无害化处理过程的功能，导出了废弃物资源化系统的生产优化条件。根据废弃物市场定价的资源含量与治污难度的函数特征，研究了在边际收益均衡和市场博弈均衡下的市场定价机制，给出了废弃物市场交易定价的求解条件。作为一个自负盈亏单位，把废弃物的购买（可正可负的）支出计入成本，资源化价值作为效益，推导了废弃物投入量作为变量的利润最大化条件。

Economic Analysis of Waste Recycling in Circular Economy System

The optimum production conditions are derived after the system structure and function of waste recycling and innoxiousness processing. The functional characteristics of recycling and recovery in the waste pricing are analyzed,the pricing mechanism of marginal revenue equilibrium and market game equilibrium are studied and the solution conditions of waste market pricing are given. As a unit with responsibility for own profit and loss,the profit maximum condition of waste recycling system is derived,where the expenditure on waste purchase is accounted in the total cost and the value of recycling is as revenue.
