A System Dynamics Model for the Environment Management of Eco-Industrial Park

As industrial chain is important for the sustainability of an eco-industrial system, we formulate a system dynamic model emphasizing on importance of industrial chain. Taking machine manufacturing industry of Xuzhou Economic Development Zone for example, a system dynamic model including 6 flows (population, material, capital, technology, water, energy) is designed. By sensitivity analysis 3 sensitive parameters including technological investment ratio, network association degree, and diversity index are identified as sensitive parameters. Corresponding scenarios are simulated and suggestions on the sustainable development of the economic development are given.
