Adaptability theory is an important tool to analyze the degree, mechanism and process of interaction in global environmental change, which provides a new perspective for the research on sustainability assessment. Taking adaptability as the starting point, this paper constructs an evaluation framework based on the three elements of sensitivity, stability and response. We use entropy weight-TOPSIS and cointegration test to analyze the spatio-temporal difference and influencing factors for the environmental adaptability of human-sea economic system in the Bohai Rim region. The results indicate that: (1) The environmental adaptability development of human-sea economic system has been under the double disturbance effect of internal and external factors. (2) Different adaptability elements and adaptability subsystems show completely different regional evolution characteristics. Human-sea environment system is less sensitive and presents "dumbbell-shaped" distribution with high in the north and south and low in the center; The stability of this system is poor and the development trend of the high east and low west; The response of the human-economic system is relatively weak and demonstrates a "grade-difference"; The adaptability of human-sea economic system is linearly related to the adaptability of human-sea environment system. (3) The environmental adaptability of human-sea economic system in the study region improves slowly between 2000 and 2014, and a cluster analysis method is applied to categorize the adaptability into four types: the city with high adaptability is Dalian; the cities with higher adaptability are Tianjin, Yantai, Qingdao, Rizhao, Dongying and Weihai; the cities with moderate adaptability are Qinhuangdao, Weifang, Yingkou and Dandong; the cities with low adaptability are Tangshan, Huludao, Binzhou, Panjin, Cangzhou and Jinzhou. (4) Environmental management, extroversion marine economy, port construction and talent support are important influencing factors that play a positive role in the environmental adaptability of the human-sea economic system.

Key words: human-sea economic system, environmental adaptability, spatio-temporal difference, influencing factor, Bohai Rim region
