基于主成分分析的江苏海洋产业综合实力评价

The Assessment on Comprehensive Strength of Jiangsu Marine Industry Based on Principal Component Analysis

江苏省沿海开发战略进入关键实施期,急需提升海洋产业的综合实力。文章首先构建了海洋产业综合实力评价指标体系,运用主成分分析法提取四个主成分:海洋科技对海洋产业的贡献、海洋产业发展能力、海洋产业发展潜力和海洋环境保护能力。然后,选取几个指标动态描述江苏海洋产业与海洋产业发达省份的差距。研究结果表明:在中国内地11个沿海省市中,江苏海洋产业综合实力排名第六。在此基础上,重点分析了江苏省海洋产业与我国发达省市海洋产业的差距,得出江苏省海洋产业的薄弱点主要表现在科技投入不足和海洋产业结构不合理两个方面。

The comprehensive strength of marine industry should be enhanced in the critical implementing period of The Ji- angsu Coastal Development Strategy. Firstly, the paper builds marine industry comprehensive strength evaluation index sys- tem. in which four principal components （contrihntion of marine science and technology to the marine industry, capacity of marine industry development, potentials of marine industry development and marine environment protection capacity） are ex- tracted by applying the principal component analysis. Then, several indicators are selected to describe dynamically the ma- rine industry gap between Jiangsu Province anti other developed provinces. The research shows that the comprehensive strength of jiangsu marine industry ranks sixth in I l coastal areas in China's Mainland. On the basis of the study, this paper focuses on the analyses of marine industry gaps between Jiangsu Province anti other developed provinces. Insufficient tech- nology investment anti unreasonable structure of marine industry are the two main drawbacks of Jiangsu marine industry.
