Data Set for the Stackelberg Game Model of Secondary Utilization of Power Batteries via Informal Channels

This dataset is the complete supporting data for the article "Research on the Game Model of Power Battery Cascade Utilization Considering Informal Recycling Channels", including the mathematical derivation process of the theoretical model, as well as a complete set of numerical simulation codes and underlying data results. In response to the reality of the disorderly expansion of informal channels (small workshops) in the new energy vehicle power battery recycling market, this study constructs a Stackelberg game model composed of government, hierarchical utilization enterprises, and formal and informal recyclers.

The dataset fully demonstrates the pricing decision-making logic of enterprises utilizing tiers under dual channel competition, as well as the market evolution effects of government subsidies and regulatory policies. The dataset mainly consists of the following three parts: Mathematical proof and theoretical derivation: Detailed records of the construction of objective functions for each game subject, the process of solving equilibrium solutions based on reverse induction, and key analytical processes such as the negative qualitative proof of the Hessian Matrix for the social welfare function. MATLAB numerical simulation source code: a core script for game equilibrium solving based on MATLAB.
