摘要：城镇化基础设施建设的可持续是我国推进新型城镇化建设的主要部分。在分析影响基础设施可持续的诸多因素基础上，引入系统动力学研究方法，从经济、社会、技术、管理、生态五个子系统构建城镇化基础设施的可持续系统模型；通过分析各子系统以及各因素之间的耦合作用机理，预测可持续系统的动力趋势；结合关键因素的优势效应给出适合城镇化基础设施可持续发展的思路，找到系统各方并行的发展模式，实现均衡发展。

Abstract：The sustainability of urbanization infrastructure is the main part of new urbanization infrastructure construction in China. Based on the analysis of factors affecting the sustainability of infrastructure，this paper introduces research methods of system dynamics，and establishes sustainability model for urbanization infrastructure from the following five aspects：economy，society，technology，management，ecology. By analyzing the coupling mechanism between each subsystem and each factor，predicts dynamic trend of the sustainability system. At last，presents effective ideas and suggestions suited for sustainable development mode of urbanization infrastructure combining advantages of major factors.

Keywords：urbanization；infrastructure；sustainability；system dynamics（SD）
