Analysis on the Evolution Mechanism of Open Environmental Protection Innovation among Equipment Manufacturing Oligopolistic Enterprises Based on Data Simulation

The global economic environment is becoming increasingly complex with the variable change in the competition regulation and the merging of technological innovation. A single equipment manufacturing enterprise cannot achieve the realization of an intelligent strategy. With the help of open innovation, the enterprise can build an intelligent manufacturing innovation ecosystem based on promoting internal re-engineering of enterprises and mutual opening of internal innovation resource processes among enterprises to strengthen cooperation. However, since open innovation is a complex collaborative innovation of multiorganizational cooperation, this paper analyzes and discusses the green open innovation cooperation strategy among oligopolistic enterprises in the equipment manufacturing industry under the influence of environmental regulation by using relevant models and theories of evolutionary game theory. In addition, the optimal combination under the existing situation is selected by using the model to simulate and analyze the selection trends and results of oligopolistic enterprises several times. The study shows that the probability of choosing an open green innovation strategy among oligopolistic equipment manufacturing firms is positively proportional to the excess benefit of open green innovation and government subsidies and inversely proportional to the excess benefit of knowledge spillover, government penalties, and the cost of open collaborative innovation and knowledge spillover between two firms.
