Analysis and Application of Quasi Ecosystem Characteristics in Enterprises Resource Management System
企业资源管理系统的仿生态系统特性分析与应用

Through wastes recycle and reuse,integrated use of resources,Clean Production,Eco-industry and developing sustainable Recycle Economy,human being has been groping for how to utilize resources more effectively and sustainablely.The issues related to Sustainable Development(SD) cover with comprehensive systematic issues of society,economy and environment,etc.This paper aims to discuss some issues about enterprises resources and sustainable development.With the help of Thermodynamics,the definition of Negative Entropy is firstly introduced in this paper to analyze the Enterprise System,the Enterprise Resources System and the Enterprise Resources Management System(ERMS).Based on the analysis of thermodynamic meanings of resources and enterprises resources,the quasi ecosystem characteristics of ERMS are analyzed to seek how to utilize enterprise resources effectively.Then the model of food chains in quasi ecosystems is taken to simulate how enterprises industry chains work to step-utilize enterprise resources.Thus the model helps us to understand how Recycling Economy operates in enterprises practices at micro and sub-macro level.Inside certain enterprise the units that recycle enterprise resources should be increased as step-utilizing chains of enterprise resources are lengthened.Among enterprises there should be some Eco-industry Parks,which gather certain different enterprises sharing common resources.As quasi ecosystem rules function among enterprises in Eco-industry Parks,the industry chain structure is finally optimized through decreasing the proportion of manufacture enterprises and increasing the proportion of service enterprises and material recycling enterprises.A case on water resources effective utilization in Eco-industry Park of Tianjin Economic and Technological Development Area(TEDA-EIP) is brought forward in the end of this paper.The case of TEDA-EIP provides us with a method of recycling and step-utilizing water resources among enterprises,which reduces pollution of wastewater and saves limited water resources.The case of TEDA-EIP proves that the quasi ecosystem characteristics of ERMS could be applied to guide Recycling Economy at micro and sub-macro level,by which enterprise resources could be utilized effectively.The thoughts related to SD and ERMS help the paper analyze the quasi ecosystem characteristics of ERMS and build up the model of step-utilizing enterprise resources,both of which would be good evidences in theory and practice.
