Evolutionary Game of Port Behavior and Government Supervision under Carbon Quota Mechanisms

This paper explores the impact of exploring government regulation on the use of green technologies in ports under the carbon quota mechanism. It shows that: (1) static reward and punishment mechanism is easy to lead to system oscillation and difficult to stabilize; (2) dynamic reward and punishment mechanism can promote the use of shore power in ports; (3) increasing government punishment can enhance the probability of shore power use and reduce the intensity of regulation; (4) increasing government incentives reduces the intensity of government regulation, and the probability of shore power use in ports decreases; and (5) moderately decreasing the carbon quota can accelerate the system to reach stability. And it provides theoretical support for policy optimization.
