The coordinative ability of regional development is one of the main characterizations of regional sustainable development. The assessment indicators and standard system of regional sustainable development have been established based on the model of coordinative development of society, economy and ecological environment in set pair analysis with integrating of theoretical analysis and empirical analysis, the qualitative analysis and quantitative analysis, according to the statistical data and materials from relative government agencies. The purpose of this study is to evaluate the coordinative ability of sustainable development in Beijing-Tianjin-Hebei Region by the method mentioned above. This study calculated the value of the coordinative ability index and the degree of social development, economical development and environmental damage, with the correspondence between the index and sustainable development coordinative ability described. By adopting similar, dissimilar and inverse relative degree and state sorting analysis from set pair analysis, the coordinative ability of sustainable development during 2000-2010 in the study region was appraised. The result shows that there is a better trend despite slight amelioration. In the light of time sequence, in this paper, the value of coordinative ability index in Beijing increased by 27.86% from the year of 2000 to 2010, which in Tianjin and Hebei are 8.87% and 18.51% respectively. The interval of little, weak, elementary and high coordinative ability are given. Beijing and Tianjin belongs to incompatible development from the year of 2000 to 2004, the coordinative ability index of which reaches the interval of weak coordination after 2006, while Hebei is always in the stage of incompatible development during the same period. The current situation in Beijing and Tianjin is better, according to the coordinative ability index about the districts, due to rapid social and economical development and slight downside of environment damage, even though the destruction to ecological environment is still heavily. It is also demonstrated that slow-growing of the social and economical development is same to with tiny change of environment damage degree in Hebei. Therefore raising forest coverage rate and solving the water problem are the primary measures to achieve sustainable and coordinative development, while some things, such as industrial structure, technology, medical treatment and education, are more urgent for Tianjin and Hebei besides that. Though the study region is the core area of Bohai Rim, one of the three leading economic zones in China, the conflict between regional economic development and the environment is becoming serious. It is exigent to research the coordinative ability of regional sustainable development due to that Beijing-Tianjin-Hebei Region created artificially does not balance the inconsistent development situation among districts. The radiation effect to Hebei was not brought by excessive concentration of industry development in Beijing and Tianjin derived from administrative division, leading to negative development in entire region. As for Hebei itself, however, one's own interests of the municipalities in the province are concerned overly and short of deep collaboration and communication among municipalities.In this sense, the application in the assessment of coordinative ability of sustainable development is significant and worth to be spread. The results presented in this study would provide scientific basis and direction to formulation and implementation for whole planning of Beijing-Tianjin- Hebei region, and also lay the foundation for sustainable development research of Bohai Rim.
