Evaluation of Marine Comprehensive Strength Based on Set Pair Analysis

The marine environment has provided a new field for the development of national power and long-term strategic advantage.Marine comprehensive strength plays a pivotal role in the realization of maritime power and measures the development level of the marine career.This paper analyzed marine comprehensive strength,including marine resources,marine economy,international competitive power of marine industries,marine science and technology,and marine infrastructure.We constructed an evaluation index system for marine comprehensive strength in line with the principles of scientificity,hierarchy,maneuverability and goal orientation.A combination weight method was used to obtain each index weight and evaluate marine comprehensive strength by set pair analysis.We found that Guangdong,Shandong and Shanghai belong to the first tier as their marine comprehensive strength is relatively strong;Liaoning,Zhejiang,Tianjin,Fujian,Jiangsu are in the second tier and have medium marine comprehensive strength.Hebei,Hainan and Guangxi belong to the third tier:they are the weakest coastal provinces regarding marine comprehensive strength.The first tier should set up modern marine industry systems and improve the quality of the marine economy.The second tier should build pillar industries and develop marine economy advantages.The third tier should strengthen contact with the land economy to improve the marine economy.The above research result provides a basis and reference for the future marine economic strategy of 11 coastal provinces.
