Note: index data are collected by the cities in the coastal areas; and the original data are dimensionless processed. China’s marine data are mainly from China’s Marine Statistical Yearbook, while other research data are from the government work reports, social development statistics bulletins, departmental policies, and documents of coastal cities. Through the purchase, collection, processing, and comparison of marine data, we found that the marine data for the research areas are relatively complete and sufficient, as well as scientific and objective, for the period 2006 to 2016; therefore, this research cycle was chosen.
