Research on the Impact of Heterogeneous Marine Environmental Regulation on High-Quality Development of the Marine Economy

Regions 1 to 11 represent Liaoning, Hebei, Tianjin, Shandong, Jiangsu, Shanghai, Zhejiang, Fujian, Guangdong, Guangxi, and Hainan, respectively. Indicators X1 to X6 reflect innovation, X7 to X10 reflect coordination; X11 to X16 reflect ecology; X17 to X20 reflect openness; X21 to X26 reflect sharing. The research findings indicate that the development of China's marine economy is uneven across regions.

Leading regions, represented by Shanghai, have scores for high-quality marine economic development that are significantly higher than other coastal areas. Next are the catching-up regions, represented by Fujian, Guangdong, Hainan, Shandong, Liaoning, and Zhejiang, where the scores for high-quality marine economic development are near the average. The third category is the lagging regions, represented by Hebei, Guangxi, Tianjin, and Jiangsu, where factors such as economic development foundations and resource endowment conditions constrain the high-quality development of the marine economy.
