| 流动摊贩与城市发展之间的矛盾一直是城市治理中的难点。本文以合肥三里庵商圈内疏导区及周边 流动摊贩区为研究对象，明确疏导区的设置使得流动摊贩管控有所改善，但忽视了非正规经济的特质与优势， 仍存在诸多问题。通过分析城市治理与摊贩特质之间的矛盾根源，反思当前困境。尝试从政府部门、城市规划者、 物业公司及摊贩自身提出多维度共同监管策略，以期为满足流动摊贩的需求提供有效帮助及为城市治理提供 合理借鉴。 |

| The conflicts between mobile vending and urban development has always been a difficulty in urban governance. This paper takes the management zone within the Sanli'an shopping district in Hefei and the surrounding mobile vending area as the research object，and confirms that the management zone improves the mobile vending governance，while weakens the features and advantages of the informal economy. The core of the dilemma is analyzed，and a multi-dimensional co-regulatory strategy is attempted from the perspectives of government departments，urban planners，property companies and vendors，with a view to providing references for meeting the needs of mobile vendors as well as optimizing urban governance. |
