Impact of Green Total Factor Productivity in Marine Economy Based on Entropy Method

In order to improve the efficiency of marine economic production and realize the sustainable and healthy development of marine economy, the spatial-temporal and dynamic evolution trend of marine economic green production efficiency in coastal areas of China is analysed by means of SFA basic model, coefficient of variation, coefficient of Gini and entropy method. It mainly includes three aspects: the result analysis of marine economy green production efficiency; the dynamic trend analysis of marine economy green production efficiency; the analysis of factors affecting marine economy green production efficiency. The results show that the factors affecting the total factor productivity of the marine economy are: development level of marine economy, marine material capital, level of opening to the outside world, marine industrial structure, marine human capital and marine environmental governance.
