Simulation Code for the Green–Digital Collaborative Low-Carbon Transition of the Port–Shipping System

This dataset contains the Python code and numerical outputs supporting the manuscript “Green–Digital Collaborative Low-Carbon Transition of the Port–Shipping System under Carbon Tax Regulation: A Differential Game Analysis.” The code reproduces the dynamic simulations, carbon-tax parameter scans, responsibility-sharing and green–digital coupling analyses, Monte Carlo simulations, and robustness tests reported in the manuscript.
