农业废弃物资源化利用交易模式及定价研究

Transaction Mode and Pricing of Agricultural Waste Resources Utilization

从系统稳定性的视角,采用演化博弈方法,通过对农业废弃物第三方资源化利用博弈模型均衡点的稳定性分析可知:受农业废弃物污染和资源双重属性的影响,收费和收购模式均具有一定的适用性,在不同条件下,存在仅收费或收购的单一交易模式以及收费与收购并存的混合交易模式;在混合交易模式中,收费与收购模式的稳定性存在此消彼长的反向变化关系,受农业废弃物中不可回收物占比的影响,收费模式与收购模式之间存在模式转换的临界点;针对混合交易模式中的收费与收购模式,分别得出每种模式下的最优定价表达式。

Adopting the perspective of system stability and the evolutionary game method,this paper analyzed the equilibrium point stability of the game model of agricultural waste third-party resources utilization.The results show that:due to the pollution of agriculture waste and the dual attributes of resources,both charging and acquisition have certain applicability,and under different conditions there are a single transaction mode of charging or acquisition and a mixed transaction mode of the both;in the mixed transaction mode,the stability of charging and of acquisition show an inverse relationship,and there is a tipping point of switch between them,which is affected by the proportion of the unrecyclable in agricultural waste;for the mixed transaction mode,the optimal pricing expression of charging or acquisition can be obtained respectively.
