Through the method of grey correlation analysis, study analyzed the economic effect and development power of China's marine economy based on China's marine economic data, which mainly come from the China Marine Economic Statistics Bulletin of the Department of Marine Strategic Planning and Economy, Ministry of Natural Resources, and the State Council of CHYXX. This paper mainly studied the data of China's total marine economy, the growth of marine primary, secondary, and tertiary industries, and the marine-related labor population in 2008–18, and calculated the per capita marine gross domestic product (GDP) and the per capita national GDP. This paper obtained the proportion of marine GDP in the national GDP. Through the min-max method, this paper analyzed the relevant data through the grey correlation analysis method and drew the following conclusion. The proportion of China's marine economy in the national economy is relatively high, and the location entropy of the marine economy has been stable at a high level of more than 3.50.
