题型：材料分析题

材料一：现行行政管理观念、体制、方式都不能完全适应社会主义市场经济的要求，政府职能转变还不到位，主要表现为：政府职能越位、缺位、错位现象大量存在，一方面，政府存在着许多不该管、管不了、也管不好的事。另一方面，该政府管的事，却没有管住、管好；权力与利益挂钩，乱收费、乱罚款屡禁不止；行政机关办事手续繁琐、效率低下。

材料二：依法行政是依法治国方略的重要组成部分，其基本要求，就是所有行政机关及其工作人员必须依照法定权限和程序履行职责，既不失职，又不越权。

材料三：深化行政管理体制改革，推进政府管理创新，是全面贯彻科学发展观的要求，是完善社会主义市场经济体制、推进改革开放和现代化建设的重要环节。要加快政府职能的根本性转变，形成权责一致、分工合理、决策科学、执行顺畅、监督有力的行政管理体制。

（1）材料一反映了什么政治现象？
