Financial support is the driving force and means for the development of marine industry. Improving the efficiency of financial support is the key to financial support. With the increasingly fierce market competition, only by relying on high-quality products and high customer satisfaction can enterprises survive in the fierce competition. Among many evaluation methods, Data Envelopment Analysis (DEA), as a non-parametric statistical method for effectively dealing with multi-input and multi-output problems, has received more and more attention in evaluating the relative efficiency of decision-making units. The adjustment and optimization of financial structure have been proved by theory and practice to promote economic growth, and financial support plays a decisive role in the development of marine industry. China's financial structure is still in the stage of scale expansion to promote the marine economy. In order to promote the improvement of marine industry, we should turn to the intensive mode of efficiency improvement. This paper extends from financial support to the study of financial support efficiency, and puts forward the method of using DEA model to evaluate and analyze the financial support efficiency of marine industry.
