：为推进我国城市政府运用大数据提升治理效能的进程，文章采用南开大学网络社会治理研究中心开发的“大数据提升政府治理效能评价指标体系”作为评价工具，对我国75个城市进行了评价研究。结果表明，在治理绩效、治理能力、制度保障和公众参与四个评价维度中，排名前20的城市政府在制度保障和治理能力方面总体表现较好，而在治理绩效和公众参与方面则相对较弱。总体来看，我国城市政府在运用大数据方面存在着区域间的不平衡，在各不同行政级别的城市间也存在明显差距。最后，提出了几点对策建议。

In order to promote the application of big data in enhancing the governance efficacy of urban governments in China, this study evaluates 75 urban governments using the "Evaluation Index System for the Government Efficacy Using Big Data" developed by the Center for Network Society Governance of Nankai University. The results show that among the four evaluation dimensions, the top 20 governments generally perform better in institutional guarantee and governance capability than in governance performance and public participation. The imbalance exists between regions as well as between cities at different administrative levels. On this basis, several suggestions were put forward.
