Analysis on the Adjustment of Marine Economic Industrial Structure Based on the Least Square Regression Model

In order to intuitively analyze and clearly understand the effect of industrial structure adjustment of the marine economy in recent years in China, modeling and empirical research on industrial structure adjustment of the marine economy are carried out. Three comparisons of marine economic industrial structure and per capita output value coefficient of the marine industry are selected as scientific measurement indexes, the ratio of regional entropy to the output value of marine scientific research management service industry is selected as the height analysis index, and the econometric model is constructed according to the influence of the scientificity and advancement of marine economic industrial structure on marine economic GDP. Based on the empirical analysis of the relevant economic data of China’s marine industry from 2008 to 2018, the model variable stationarity test and least squares regression analysis showed that the fitting degree of the model was good and significant; with every 1% increase in the scientificity and height of marine economic industrial structure adjustment, the marine economy increased by 1.88% and 2.80%, respectively. The development of marine science and technology can promote the rise of the marine economy. According to the model, the adjustment strategy of the marine economy industrial structure is made to further promote the development of the marine economy.
