Evolutionary Game for Dual-Subject Coopetition Relationship in the Product–Service System

In the product–service system, variations in the service capabilities of equipment manufacturing enterprises (EMEs) and equipment operating enterprises (EOEs) will change the coopetition relationship. Firstly, this study develops an evolutionary game model to analyze how the relationship between EMEs and EOEs evolves. And then MATLAB simulations are used to examine the factors influencing their coopetitive strategies. Finally, key findings include (1) the variations of market service demand and technology diffusion revenue drive strategy evolution; (2) the unilateral cooperation cost presents the law of diminishing marginal effect, especially on EOEs; (3) an optimal profit distribution ratio exists, which has the most impact on the probability of cooperation. This study informs coopetitive development and decision-making in the service-oriented transformation of the manufacturing industry.
