The key of the sustainable development of human society is to realize the coordinated development among the energy system, the economic system and the environmental system. A quantitative analysis of their coordination is one of the core concerns in this field. With the rapid economic development, Ningbo becomes a new member of China's "trillion club". Taking Ningbo as an example, this paper establishes an index system of the energy-economy-environment (3E) system, analyzes the development level of the energy system, the economic system and the environment system in Ningbo and its counties, then calculates the coupling and coordination degree among the three systems with the algorithm for the coupling coordination degree. It is shown that the degree of the coupling and coordination of the three systems is increasing in the process of the economic development of Ningbo City, which is in a good and sustainable development state.
