Dynamic analysis of green investment decision of manufacturer.

Abstract

With the continuous development of green manufacturing concept, more and more enterprises attempt to increase their green investment to promote the utilization of resources. In order to help enterprises make the optimal green investment decision, firstly, this paper constructs a duopoly competition game model based on the manufacturer's limited rationality. Then, the Nash equilibrium solution of the system is discussed by using the reverse induction method. Finally, the system is simulated to study the green input decision and the impact of green input cost on the manufacturer's output and profit. By adding external control signals, the chaos state of duopoly competition game model is restrained. The results show that the manufacturer's optimal green investment portfolio lies in the stable region of Nash equilibrium. Secondly, in the duopoly competition game model, when the initial value of green input adjustment rate and cost changes slightly, the evolution of production and profit of manufacturing enterprises will be greatly different. Thirdly, the study revealed that the addition of external control signals can effectively control the chaotic situation of the market and subsequently restore the order of the participants and the market. Therefore, our research provides a reference for enterprises to make green input decision; improve the efficiency and rationality of enterprise management and further promote the green development of enterprises.
