摘要
According to the different supply and demand relationships of by-products between the upstream and downstream enterprise in the industrial park, the Stackelberg game model for pricing of waste recycling was established in three scenarios: non-symbiotic, partially symbiotic, and fully symbiotic. Through the comparison of model results and the analysis of parameters, the condition of establishment for eco-industry symbiosis, pricing decisions for waste recycling and recycled products were studied, and a case was introduced to verify the results of the model and applied to the waste value circulation process. The research results show that in the game model where the downstream enterprise is a leader, when the marginal cost of recycling is lower than the cost of purchased raw materials, it is easier for enterprises to establish the relationship of eco-industry symbiosis; with the increase in the amount of supply of byproducts and the gradual improvement of the symbiotic degree, pricing of waste recycling continues to decline, and enterprises get more profits; internal and external factors of enterprises affect the formation of the symbiotic relationship and the pricing of recycling, and the coordination of interests among enterprises is needed to promote the waste recycling in the industrial park and the value circulation of waste. © 2019, Editorial Board of Journal of Systems Engineering Society of China.
