Research on Sustainable Port: Evaluation of Green Port Policies on China's Coasts.

Increasing port pollution has forced governments to enact policies related to green ports to maintain the sustainability of maritime transportation. In this article, we established a policy evaluation system based on the PMC (policy modeling consistency) index model to evaluate 17 green port-related policies currently enacted on coastal China, providing a new perspective on existing maritime policy evaluations. The results show that the average overall consistency of the policies is 7.16 with "good" performance, and no policy is "low" consistency. While this suggests that the existing policy design is sound, some deficiencies exist, such as insufficient cooperation between governments and insufficient emphasis on incentives. We provide recommendations for improvement based on these deficiencies and analyzed and optimized every policy in detail. Meanwhile, we found that policy texts from southern ports perform better, contrary to the previous view. The discovery could be a good entry point for future research. We also offer some suggestions for the development of green ships in China. The research makes these contributions and may provide some insights for policymakers. [ABSTRACT FROM AUTHOR]
