【摘要】 提升图书馆的知晓度和影响力，是深化全民阅读、建设书香中国的关键；其中“公共图书馆服务宣传周活动”最具代表性，它是在固定时段内高频推进、覆盖全国的一场大型阅读推广行动。本文以全程参与2025年宣传周活动的700家一级图书馆为样本，系统采集其官方微信公众号在此期间发布的全部推文，运用LDA主题模型对文本进行主题挖掘，从全国整体、东部—中部—西部三大区域、省—地—县三级行政层级的3个维度，剖析图书馆行业的关注热点及其分布特征。研究发现：全国图书馆界高度聚焦“全民阅读推广”“少儿阅读服务”“文化艺术与科普”“科技赋能阅读”四大主题，区域层面呈现“东部引领创新、中部深化服务、西部夯实基础”的阶梯差异，层级层面则形成“同中有异、协同互补”的系统性格局。历经三届的公共图书馆服务宣传周活动，已成为我国图书馆服务由“资源导向”向“需求导向”转型的重要契机。为此，全国图书馆界应进一步提高认识、协调行动，共同推进图书馆服务更高质量、更有效率、更加公平的发展。更多还原

【Abstract】 Enhancing public awareness and social impact of libraries is key to deepening nationwide reading and building A book-loving China, among which the Public Library Service Publicity Week stands out as a typical,high-frequency, nationwide campaign concentrated in a single period. Taking 700 first-tier libraries that participated in the entire 2025 Publicity Week as a sample, this study systematically collects all related posts published on their official WeChat accounts during the event. By applying the LDA topic model to the corpus, we analyze the distribution of professional concerns at three levels: nationally, across eastern/central/western regions, and among provincial/prefectural/county libraries. The findings show that the Chinese library field concentrates on four dominant themes: Nationwide reading promotion, Children’s reading services, Culture, arts & science popularization and Technology-empowered reading. Regional libraries exhibit a step-wise pattern: the east leads in innovation, the central deepens services, and the west consolidates foundations. Across different administrative tiers, libraries display a systematic landscape of similar yet distinct,complementary and coordinated development. The Publicity Week has become a pivotal moment for shifting library services from Resource-oriented to Needs-oriented. Accordingly, the national library community should raise awareness and act in concert to advance library services that are higher-quality, more efficient,and more equitable.更多还原
