生态产业链模式下企业的生态——经济系统的动力学模拟研究

将传统上孤立研究的生态、经济系统利用系统动力学耦合成一个复杂的系统,对生态产业链模式下企业层面上的生态经济系统的协调性进行了分析,运用系统动力学相关理论建立了人力资本子系统、污染存量子系统、资源子系统、生产技术子系统、经济利润子系统五个子系统,研究了企业经济增长与污染控制和资源消耗之间的反馈关系,并用Vensim PLE软件建立了生态产业链模式下的企业生态经济系统的动力学模型。通过对以生产热轧板材的钢铁联合企业为例进行的仿真分析,得出企业在一定条件下可以达到生态—经济系统的协调性。最后,从政府的扶持、企业的积极参与以及公众的引导三方面探讨了促进企业实施循环经济、达到企业的可持续发展目标的措施与建议。

System Dynamics Simulation of Eco-economic System of Enterprises in the Ecological Industry Chain

Ecological and economic systems,which are studied traditionally,are united to be an integrated complex one with system dynamics.The coordination in the firm-level eco-economics system is analyzed,and five sub-systems are established,including human capital,pollution,resources,technology and profits sub-systems.The theory of system dynamics is developed to illustrate the feedback among economic growth,pollution control,and resource consumption.And the system dynamics model is built up by Vensim PLE.This paper takes the integrated steel companies for an example of simulation and analysis,thus leading to the fact that enterprises can reach the balance between ecology and economy at some extent.And this paper also puts forward some measurements and suggestions to encourage the enterprises to implement the circular economy according to the government's supports,enterprises' participation and public inducing effect.
