Abstract: This paper builds the evaluation indicator system for water use efficiency and coordinated development of economy coupling in Liaoning coastal economic belt (LCEB). Firstly, using improved mutation model to evaluate status of LCEB water use efficiency and the economic development of each subsystem from 2001 to 2010. Secondly, using coupling coordination model to evaluate water use efficiency and the coupling coordination degree of economic development of every city of LCEB. The results show that the coupling degree of water use efficiency and the economic development of LCEB increased from 0.437 to 0.498, which is slowly improving, but it has been in the stage of resisting. The gap of water use efficiency and economic development level decreases continuously, and the coupling coordination degree increased from 0.254 to 0.408, which showed a trend of increase but still at the mid-low level of coordination. Water use efficiency and economic growth of every city of LCEB are in a rising trend, water use efficiency of Dalian is the best with an evaluation value reaching 0.887, Jinzhou, Yingkou and Huludao are in the second place, Dandong and Panjin at the worst level with evaluation values being 0.604 and 0.535. The economic development level of Dalian is the highest, Yingkou and Panjin are at intermediate level, Dandong, Jinzhou and Huludao are at the lowest level. The coupling degree of every city in the stage of resisting, and in a rising trend. The coupling coordination degree of Dalian and Yingkou have reached 0.457 and 0.401, and entered the stage of moderate coordination from low-grade coordination phase,and showed a rising trend. The coupling coordination degree of Dandong, Jinzhou, Panjin and Huludao still at the low level of coordination and showed a fluctuated increase.The economic development of every city falls behind the improvement of the efficiency in water usage, which causes the coupling coordination being in the mid-low grade period. The regional disparities among the coupling degree and coordination degree of LCEB are decreasing, and the coordinated development trend of economic belt becomes more and more apparent.
