Evolutionary game analysis on behavior strategies of multiple stakeholders in maritime shore power system

Abstract

This paper focuses on the mechanism of interaction among the strategic choices of a shore power system including government, port enterprises, and liner companies. Based on an evolutionary game model, the influence of shore power implementation on the evolutionarily stable strategies (ESS) of the multiple stakeholders is discussed. The observations show that whatever stage they are in and whatever their initial strategies are, the government always chooses to use incentives, port enterprises prefer to implement shore power, and liner companies choose to modify shore power facilities. Furthermore, the initial strategy of government has a significant influence on the strategic evolution of port enterprises and liner companies. Beyond that, the higher the policy cost and the bigger the social benefits of implementing shore power without government incentives, the sooner the government will move to the “non-incentive” strategy.
