从政策主体、政策工具和政策效力三个维度出发，运用Ｎｖｉｖｏ１２软件和ＰＭＣ指数模型构建城市洪涝灾害治理政策的三维分析框架，对城市洪涝灾害治理相关政策文本内容进行量化分析。从政策主体维度看，洪涝问题的复杂性需要跨部门合作解决，各级地方人民政府、防汛指挥部和水利部门是应急管理部门成立之前的洪灾治理核心主体。应急管理部成立后便在洪涝灾害治理中占据重要位置，机构改革初具成效。但相关政策更新晚于部门实践，政策主体职能多集中于应急救援与灾后救助，这些不利于不同主体之间的合作，改革仍需进一步推进。从政策工具维度看，形成了以命令控制型政策为主，经济激励型政策为辅，社会参与型政策为补充的政策工具体系。从政策效力维度看，评价等级在良好或优秀的政策占半数。部分政策在覆盖面、功能等方面仍有不足，直接影响治理效能。探究城市洪涝灾害治理政策的特征及其效力，可为我国洪涝灾害治理政策制定及体系优化提供参考

Based on the three dimensions of policymakers, policy instruments and policy effective ness, this paper constructed a threedimensional analysis framework of urban flood disaster governance policies by using Nvivo 12 and PMC index model, and made a quantitative analysis. This paper found that in the dimension of policymakers, the complexity of flood problems needs to be solved by crosssectoral cooperation. The local people′s governments, the flood control headquarters and the Ministry of Water Resources were the core subjects of flood disaster governance before the establishment of the Ministry of Emergency Management. After 2018, the Ministry of Emergency Management has played an important role in flood disaster governance, and the institutional reform has begun to take effect. However, the functions of policymakers are mostly focused on emergency rescue and post isaster relief, and the relevant policies are updated later than the department practice, which hinder the cooperation of different subjects. The reform needs to be further promoted. In the dimension of policy instruments, the policy instrument system is dominated by CAC policies, assisted by economic incentive policies and supplemented by social participation policies. In the dimension of policy effectiveness, half of the policies are perfect or good consistency. Some policies have deficiencies in coverage and functions, which directly affects governance efficiency. Exploring the characteristics and effectiveness of urban flood disaster governance policies can provide reference for policies formulation and system optimization.
