推进国家治理现代化包括推进国家治理体系和治理能力两个方面的现代化。为实现国家治理现代化的长期目标，根据政府注意力分配理论，政府需要持续保持相当的注意力于国家治理建设，因此有效测度政府在国家治理建设的注意力具有重要意义。鉴于政府注意力具有不可直接观测性等问题，本文提出一种用于提取文本特定主题信息的定向隐含狄利克雷分布（LDA）模型，以人民日报、光明日报和新闻联播文字稿等官方媒体为语料库，首次构建基于新闻文本的国家治理政府注意力指数，有效测度政府在国家治理领域所投入的注意力，并基于该指数实证研究政府注意力的治理效应与信息效应。研究发现：定向LDA模型可以提炼得到更纯净的定向LDA的关注度，无需设定主题数、不过度依赖人工构建的词典且无需人工审核；基于新闻文本构建的国家治理政府注意力指数能有效反映政府对国家治理现代化关注度的动态变化；政府对国家治理现代化的重视可以有效转化为治理效能的提升，同时政府透过官方媒体的宣传也能有效带动公众对国家治理的关注度。对国家治理政府注意力的测度与研究，可以加快国家治理现代化理念在各级政府与民众间的传播与实现，为推动国家治理现代化进程提供参考。

Advancing the modernization of national governance involves the modernization of both the national governance system and governance capacity. In order to achieve the long-term goal of modernization of China's governance, according to the theory of government attention allocation, the government needs to maintain considerable attention to the construction of national governance, so it is of great significance to measure the government's attention to the construction of national governance effectively, but the government's attention has such problems as being unobservable. This paper proposes a specific LDA model for extracting topic-specific text information,and takes official media such as People’s Daily,Guangming Daily and the text transcripts of CCTV News Broadcasts as the corpus,constructs for the first time a government attention index for national governance based on news texts,effectively measures the attention invested by the government in the field of national governance.Based on this index,the governance effect and information effect of government attention are empirically studied.The study finds that:the specific LDA model can be refined to obtain a purer directed LDA attention,and does not need to be given the number of topics,does not overly rely on manually constructed dictionaries,and does not need to be manually audited;the government attention index of China’s governance based on the news texts can better reflect the changes in the government’s attention to the modernization of China’s governance;the government’s attention can be effectively translated into the improvement of the governance effectiveness,and the government’s publicity through the official media can also effectively drive the public’s attention to national governance.The measurement and study of government attention for national governance can speed up the communication and realization of the concept of modernization of national governance,and provide support for the progressing of the modernization of China’s governance.
