Abstract: Regional water-energy-food (WEF) synergetic development evaluation is an important prerequisite for promoting regional cooperative security development effectively. Under the framework of regional WEF nexus system, the concept of regional WEF synergetic development was proposed based on the synergetic theory, and evaluation index system was constructed from the aspects of function, structure and efficiency. The development degree was evaluated by measuring the gap between the existing state and the ideal state based on the distance synergy method. Considering the synergy relationship between each subsystem, the grey correlation analysis method was used to determine the pull factors between each subsystem, and then the synergy degree was calculated. The synergetic development degree was calculated by integrating development degree and synergy degree. This method was used to analyse the WEF synergy development degree of Ningxia Hui Autonomous Region in China from 2001 to 2015. The results show that the WEF synergetic development of Ningxia was increasing but still at a low level, food subsystem had significant pull function to the water and energy subsystems. While improving the development degree of each subsystem, Ningxia needs to strengthen the collaborative development among the subsystems to improve the synergetic development of regional water, energy and food.
