Dataset of Appendix Derivations and Equilibrium Solutions for Dynamic Co-opetition Strategy of Proprietary Component Manufacturers

This dataset is the supplementary appendix data for the paper Choice of co-opetition strategies for proprietary component manufacturers under dynamic environment, containing complete equilibrium solutions of dynamic game models, mathematical proofs of propositions and lemmas, as well as inferior strategy analysis and equilibrium results. It covers two models: PCM-OEM independent pricing and Nash bargaining, involving four mainstream strategies: Monopoly 1, Co-opetition 1, Co-opetition 2, and Co-opetition 3. Additionally, it provides three other possible inferior strategies (Monopoly Ⅰ, Co-opetition Ⅱ, Co-opetition Ⅲ) and their full equilibrium solutions, with clear demonstration of their non-optimality. Presented in formula derivations, closed-form solutions, Hessian matrix tests, KKT conditions and profit comparisons, the dataset supports direct result reproduction, model validation and theoretical expansion of supply chain dynamic co-opetition, providing traceable and verifiable mathematical support for research in operations management, game theory and supply chain decision-making.
