A Dynamic Model for Simulation of the Scale of Industrial Chain of Construction Waste Reclamation in China

The scale of the industrial chain for construction waste reclamation in China is still at a small magnitude with a relatively slow development rate, yet to form an industrial chain that is mature. With the industrial chain theory, this paper takes Guangzhou as an example to construct a simulation model of the scale of industrial chain of construction waste reclamation based on system dynamics. As the results show: (1) though the subsidy policy carried out by the government has a significant effect on the development of the industrial chain of construction waste reclamation, a greater amount of compensation will not necessarily lead to a larger scale of industrial chain of construction waste.(2) The inventory optimization management is conducive to promote the development of industrial chain of construction waste. (3) The governmental compensation amount of RMB 50,000 per 10,000 tons in the next 5 to 10 years will be the optimal to ensure the rapid development of the industrial chain of construction waste. (4) The scale of the industrial chain of construction waste reclamation, the inventory of the dealers and the inventory of resource-oriented enterprises interact and mutually constrain, implying that with the expansion of the production scale of resource-oriented enterprises, the oscillation amplitude of the inventory of the dealers will become greater while the frequency will be smaller .The conclusion of the study provides reference value and theoretical basis for the development of industrial waste resource industry chain.
