Abstract: An Agro-industrial compound eco-industrial park is a society-economy-nature symbiotic system integrating agriculture and industry. A small-scale "enterprise and peasant household" agro-industrial compound eco-industrial park with a product-waste exchanging framework model is built up, using the Agent modeling method. Its economic, environmental and social benefits are analyzed through systematic simulation, and impacts and effects of the agro-industrial symbiosis on development and evolution of the agro-industrial compound ecosystem discussed in depth from the viewpoint of system simulation. Results of the simulation show that total output, total profit and symbiotic turnover of the park all display a stably rising trend along with cyclic changes and the increase is getting more obvious when symbiotic enterprises join in. The waste recycling rate in the park grows rapidly, the pesticide and chemical fertilizer application rates reduce gradually, and the organic manure application rate increases. Development of the park brings about a high proportion of eco-farming households, indicating that more and more farmers choose the path of eco-farming.
