生态产业共生网络运营成本及其优化模型开发研究

从构成生态产业共生网络的微观要素———企业环境责任入手,开发了基于企业环境责任市场化机制的生态产业共生网络运营成本模型,并对模型假设做了改进研究.模型研究结果表明,环境责任代理企业的环境责任履行成本是影响生态产业共生网络运营总成本大小的关键要素,而环境责任委托企业和中间物流企业的各种参数对生态产业共生网络运行总费用的影响相对较小.基于这种认识,最后又探讨了影响代理企业运营成本的主要因子,并对费用优化模型做了应用研究.

Operational Cost and Optimization Model of Running Eco-Industrial Symbiotic Network

Eco-industrial Symbiotic Network(ESN) is a complex ecosystem of society,economics,and environment,which consists of multiple related enterprises on the basis of symbiotic and competitive mechanism.Its well-being and steady performance is the core to develop Circular Economy(IE),which,is encouraged by Central Government and being developed very quickly in China as a new strategy to approach sustainable development by improving the resources productivity and eco-efficiency of production and consumption,and at the same time decreasing the pollutants discharge.The paper explores the five kinds of environmental responsibilities of company in the eco-industrial symbiotic network: environmental safety and health training,environmental/ecological design,green/sustainable consumption knowledge training,extended producer responsibility,and wastes recycling,and proposes its operational mechanism in terms of market-based principles.Furthermore,the research develops a cost-based Model to evaluate the optimization performance of Eco-Industrial Symbiotic Network.The results show that the operational cost of environmental responsibility agents is the greatest part of the whole network performance cost,while the operational cost of enterprises who implement environmental responsibilities is just a little part.Therefore,the paper finally approaches the important factors that affect the operational cost of environmental responsibility agents and provides a case study on the model developed.
