Abstract:The environmental protection has long\|term and practical significance in present market economy situation. The pollutant management of thoughout the entire production processes has been one of the most effective ways. How to achieve a win\|win situation between economic development and environmental protection through the construction of eco\|industrial symbiosis systems in a market economy has become a central and difficult issue. It becomes crucial to achieve the stability of eco\|industrial symbiosis system in a market economy.
This paper focuses on the node stability of eco\|industrial symbiosis system from the view of environmental economics, and set up the Node Symbiotic Economics Model on the enterprises of eco\|industrial symbiosis system by analyzing relationship on the pollutants recycle of the inter\|node interconnected enterprises. Through the observation of the supply change in the enterprise′s recycling contaminants at the node based on the mathematical solutions to the model, the effects of outside disturbances on the balance of supply and demand has been studied.
If the elasticity of the product price is equal to or less than 1, the node can achieve conditional stability and if the elasticity of the product price is more than 1, the node will fluctuate periodically around a stable point, and even chaos can appear.
In conclusions, we have to set up a responding mechanism of the inter\|node pollutants recycling market economics to preserve the stability of system and achieve the sustainable development of the society, economy and environment under simplified Eco\|industrial Symbiosis System Node Model in this paper. Consequently we can achieve a win\|win situation between economy development and environmental protection in a market economy by establishing Eco\|industrial Symbiosis System.
