脆弱性分析是可持续发展的重要研究内容。从敏感性与应对能力两方面构建经济系统脆弱性指标体系，运用客观赋权、集对分析、障碍度评价公式等方法对2011年中国沿海地区经济系统的脆弱性空间分异特征、机理、障碍因素进行评价分析，结果表明：①从整体看，中国沿海地区经济系统脆弱性普遍较高且类型空间分布整体分散、部分连片集中，空间差异性显著，其中华南、东北沿海地区的经济脆弱性明显高于华东、华北沿海地区，呈现出较高脆弱与高脆弱特征。②从分区看，中等脆弱地区集中在京津、江浙和广东等经济较为发达的地区，该地区具有高敏感性与高应对性的特征；辽宁、河北、福建、广西和海南等地区的经济系统脆弱性较高，主要特征表现为高敏感性和较低的应对能力。③通过对沿海各地区经济系统脆弱性障碍因子的分析，提出中国沿海地区11省、市、自治区经济系统可持续发展建议。%Reduced vulnerability and coordinated sustainable development of land and marine econ-omy are the ultimate goals of economic system vulnerability studies.By the connotation of eco-nomic fragility in land and sea coordination system,the economic system vulnerability index sys-tem was established from the aspects of sensitivity and response capacity.The spatial differentia-tion,mechanism and barrier factors of coastal economic system vulnerability in China of 2011 were evaluated and analyzed by using objective empowerment,set pair analysis,and disorder formula. The results showed that:① The vulnerability of China's coastal economic system is generally high.The Spatial differentiation was significant and overall dispersion,partly contiguous concen-tration.The economic vulnerability in south and northeast coastal areas was significantly higher than that in the east and north,showing a higher vulnerability and vulnerability characteristics.② Moderately vulnerable areas were concentrated in Beijing,Tianjin,Jiangsu,Zhejiang,Guang-dong and other economically more developed regions,where there were higher sensitivity and higher responsibility.High economic system vulnerability areas were concentrated in Liaoning, Hebei,and Fujian,where there were high sensitivity and low coping capacity.Guangxi and Hainan had extremely high vulnerability of economic system,with the highest sensitivity and lowest cop-ing capacity.③ Through the barrier factor analysis of coastal regional economic system vulnera-bility,the sustainable development proposals of coastal economic system of China's 11 provinces, autonomous region and cities were put forward.
