Outline
To further standardize the management of ship dismantling, it is essential to evaluate and analyze relevant policies as a basis for improving the full life cycle management system of ships. This paper reviews and analyzes 42 policy documents issued by governmental and industrial organizations over the past five years. Based on the content analysis of these policies, a Policy Consistency Index model (abbreviated as the "P Index Model") is established. The ship dismantling policies are categorized into three types: macro guidance, supplementary refinement, and guidance and encouragement. Representative policy documents are selected as evaluation targets, and their rationality is empirically analyzed. The results indicate that China's ship dismantling policies require improvements at three levels. At the national level, it is recommended to establish a coordinated ship dismantling management mechanism involving relevant regulatory departments and to develop unified planning and industry support policies. At the local level, local governments should promptly formulate and implement specific measures to ensure effective policy enforcement. At the industry level, associations need to enhance communication and collaboration with local governments, particularly in establishing consensus on the qualifications of compliant ship dismantling companies, to jointly promote the standardized development of the industry.
