区域发展尤其是区域平衡发展，涉及诸多方面的协同发展。依据1994年上海市长宁区总体规划编制及其二十多年来的实施情况，分析该区从不平衡到平衡发展的系统演变，可归纳为区域发展空间协同、区域发展时序协同、区域发展要素协同等三大方面具体的实践经验。长宁区的经验表明，区域发展从不平衡发展到平衡发展是能够实现的；区域平衡发展是时序上的平衡发展、空间上的平衡发展、要素上的平衡发展的综合；区域平衡发展是梯度推进的；区域平衡发展是可以测度的。因此，今后我国区域发展在从不平衡发展到平衡发展过程中，要注重各个区域的自身区位优势、资源禀赋优势、发展基础和条件，进行错位发展、同时发展和协同发展。

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.
