The island is a strategic bridgehead to develop and utilize marine resources and an important part of the human sea coupling system. With development of islands,ecological environmental problems gradually appear. Islands are facing unprecedented double pressure and challenges from the ecological environment and social development. Island economic vulnerability refers to an unsustainable state when the development of human-earth system in the island economy resists disturbances from various internal or external natural factors. Here we conducted island economic vulnerability assessments using a comprehensive index assessment method based on 38 parameters across five aspects(natural basis,resources,eco- environmental systems,economics and social development). In addition,standard values of measurements were established and used to evaluate overall island economic vulnerability and spatial differentiation. We found obvious differences in vulnerability across the 12 island counties and can be divided into four grades:Putuo District,Dinghai District,Yuhuan County and Dongshan County have low vulnerability;Shengsi County,Changdao County and Changhai County have weak vulnerability;Daishan County Pingtan County and Dongtou County have moderate vulnerability;and Chongming County and Nanao County have high vulnerability. Island economic vulnerability shows remarkable spatial differentiation regarding regionalization and clustered distribution. This study provides a scientific basis for the sustainable development of island economies and their reasonable development.

Key words: island economies, vulnerability assessment, spatial differentiation, island county
