中国海岛县域经济产业演进及其竞争力评价

摘要

Islands are special regional units with unique development models and pathways and because of their locations, resources and environmental advantages, play an important role in the process of national modernization. Here, industrial coefifcient variation and shift-share methods were used to explain the evolution of island county economies and the competitiveness of their industrial structures. We found that industrial structures in island counties have undergone a complex evolution, have not followed a pure levo-rotation mode or dextro-rotation mode, and have experienced mixed evolutionary modes. The industrial structures in island counties are relatively simple, and the evolution of industrial structures in island counties has an apparent leaping feature. Last, the economic development of 12 focal island counties were divided into ifve categories in accordance with analysis of their economic development:Competitiveness Strengthened and Structure Optimized;Competitiveness Strengthened but Structure Declined; Competitiveness Weakened but Structure Optimized; Competitiveness Weakened and Structure Declined;and Structure Relatively Stabilized.%海岛是一个特殊的地域单元，拥有其特有的发展模式和路径，近年来随着海洋国土地位的提升，国内外学者对于海岛的研究也随之增多。本文以我国海岛县域经济体为研究对象，从分析我国海岛县域经济体产业结构入手，采用产业变动系数法和偏离份额分析方法对海岛县域经济的演进以及竞争力进行了研究，研究发现：海岛县产业结构演进是左旋和右旋的结合演进模式，海岛县产业结构相对单一，产业结构演进的跳跃性特征明显。根据海岛经济发展水平分析，将12个海岛县的经济发展分为竞争增强结构优化型、竞争增强结构衰退型、竞争减弱结构优化型、竞争减弱结构衰退型、结构相对稳定型5种类型。
