【摘要】 在全国统一大市场建设进程中，政府采购既是优化营商环境、规范财政支出的关键环节，也是推进高质量发展的重要政策工具。现有研究既缺乏对政府采购政策动态演进的追踪分析，也未能全面呈现政府采购政策的内在逻辑与发展趋势。基于中央层面发布的政策文本，结合现有研究脉络构建“决策—执行—效果”分析框架，借助内容分析法对其进行系统梳理与编码分析发现，政府采购政策的演进脉络可划分为制度建立期、制度完善期、制度深化期与制度创新期四个阶段。其演进逻辑主要体现在目标扩容、动力转化、机制创新、技术优化、价值跃迁等方面，呈现从单一到多元、从纵向到协同、从适应到赋能等多重复杂面向。有鉴于此，需要通过相关政策来进一步推进政府采购的数字化转型，持续释放政策效能，为国家治理体系和治理能力现代化提供政策保障与支撑。更多还原

【Abstract】 In the process of building a unified national market, government procurement serves not only as a critical mechanism for optimizing the business environment and regulating fiscal expenditure, but also as an essential policy instrument for promoting high-quality development. However, existing research lacks dynamic tracking analyses of the evolution of government procurement policies and has yet to fully reveal their internal logic and developmental trajectory. To address this gap, this study examines 696 policy documents issued at the central level and constructs a “decision-implementation-outcome” analytical framework, drawing on both existing research and content analysis methods for systematic review and coding. The findings indicate that the evolution of government procurement policy can be divided into four stages: institutional establishment, institutional improvement, institutional deepening, and institutional innovation. Its developmental logic is manifested in five dimensions —— goal expansion, driving force transformation, mechanism innovation, technological optimization, and value transition —— characterized by a shift from singularity to diversity, from vertical control to collaborative governance, and from adaptation to empowerment. Accordingly, government procurement policy should further advance digital transformation, continuously unlock policy effectiveness, and provide institutional safeguards and support for the modernization of the national governance system and governance capacity.更多还原
