The Impact of Green Financial Agglomeration on the Ecological Efficiency of Marine Economy

Compared human capital with marine economic and technological efficiency, the contribution of physical capital to the marine economy is greater. During the sample period, the marine economic and technical efficiency of China's coastal areas showed an overall upward trend. After entering the "Twelfth Five-Year Plan'', the growth rate of marine economic and technological efficiency accelerated significantly. From the perspective of the region, the efficiency values of Shanghai and Guangdong are always in the higher efficiency range. Tianjin, Shandong and Jiangsu rise from the medium efficiency range to the higher efficiency range, and Hebei rises from the lower efficiency range to the medium efficiency range.
