The Evolution of Marine Industrial Structure Based on Macro-Micro Analysis

Abstract

The influence of marine economy in the economic and society of coastal countries is becoming more and more significant, and the changes in the marine industrial structure will bring a series of impacts on the social and economic development. By analyzing the relationship between marine industrial structure and industrial efficiency, the feedback model of industrial efficiency—industrial structure is established. According to the evaluation method of marine industry efficiency and the DEA model of super efficiency, the evaluation index of input and output efficiency of marine industry is screened, and the change process of marine industry efficiency in the 2001–2017 years is calculated and combined with industrial knot. The evolution process of marine industry is analyzed, and the changing path of industrial efficiency in the evolution of marine industrial structure is expounded. It is found that during the last 20 years, the evolution process of marine industrial structure can be divided into three main stages, namely, the extensive development period of the marine industry, the period of structural adjustment, the period of the development of the new kinetic energy of the marine industry, with the significant difference in the fluctuation of the marine productivity in the different periods of the evolution of the industrial structure. Sign. Finally, according to the development trend of marine industry, we put forward suggestions for the development of marine industry.
