Regional development, especially balanced development, involves coordinated development of many aspects. Based on the overall planning of Changning District, Shanghai in 1994 and its implementation in past 20 years, this paper systemically analyzes the change from unbalanced development to balanced development of Changning. The result shows three concrete practices in regional development, that is, space coordination, time coordination and element coordination. The case of Changning shows that the change from unbalanced development to balanced development is achievable. Balanced development result from time, space and element coordination. Balanced development has a gradient and it is measurable. To move from unbalanced development to balanced development, we must carry out misplaced development, simultaneous development and coordinated development of different regions by paying attention to each region's own location advantages, resource endowment advantages and development foundations and conditions.
