Research on Marine Ecological Civilization Policies in Shandong Province Based on Content Analysis

The policies of marine ecological civilization involve multiple policy areas such as marine economy, marine environment, and marine society. This paper sorted out 54 related policies of marine ecological civilization in Shandong Province, constructed a co-word matrix of policy keywords, and used co-word analysis method to conduct quantitative analysis. Through the measurement of policy network centrality, policy theme groups and structural holes, the coordination of policy contents and the centrality of policy points were analyzed. The study has found that among the comprehensive policies for marine ecological civilization construction in Shandong Province, the marine ecological environmental protection policies have more focuses and have formed a relatively complete system, but the relevancy of the policy points of marine science and technology innovation related to marine support policies is not high, and the support for marine environmental protection technology innovation is not strong. These discoveries are also reflected in the subsequent content analysis of marine social support policies, and they also affect the coupling degree between the marine ecological environment and marine ecological society in Shandong Province to a certain extent.
