Abstract
Reducing carbon emissions has become a common goal in today's world for the protection of the environment, and the shipping industry, as an important force in the development of global trade, will be unavoidably involved in this conversion. This research paper develops an evolutionary game model between port and shipping enterprise under the differentiated carbon tax policy, analyses the evolutionary stabilization strategies between port and shipping enterprise, and explores the influence of relevant influencing factors on the evolutionary path. The results show that the differentiated carbon tax policy can effectively incentive port and shipping enterprise to adopt shore power technology, and the greater the difference between carbon taxes the more obvious the promotion effect of shore power. In addition, lowering the construction and operation costs for port and shipping enterprise to use shore power technology, and increasing other costs of not using shore power technology can contribute effectively to the willingness of shipping companies to utilize shore power.
