作为亿万民众共同精神家园的网络空间，是培育和践行社会主义核心价值观的重要场域。运用大数据方法深入研究党政微博关于社会主义核心价值观的传播实践，对于科学把握核心价值观网络传播规律和有效提升核心价值观网络传播效果，具有重要的理论价值和现实意义。论文在对社会主义核心价值观网络传播的指导思想、理论基础和研究方法进行分析阐述的基础上，提出社会主义核心价值观网络传播的三个核心要素——传播内容、传播话语、传播路径，进而选取新浪微博为传播载体和150个党政微博为传播主体，引入大数据分析手段和方法，构建了社会主义核心价值观网络传播的三要素分析框架。在社会主义核心价值观传播内容方面，研究发现党政微博对核心价值观的基本内容传播呈现出总体均衡、突出重点、逐步增长的特征，形成了多主体协同联动、各有特色的基本内容生产机制，协调运用了各类思想政治教育内容形态进行价值观传播，微博传播与社会认同之间关系密切。论文提出，党政微博在传播核心价值观基本内容中存在“阶段式传播”问题，传播行为与网络受众的价值偏好之间存在一定错位，传播声量及其整体性亟待提升，思想观念形态嵌入传播的程度和效果也亟待优化。在社会主义核心价值观传播话语方面，研究发现党政微博注重以集体叙事为主导，重视运用情理交融型语言风格，审慎运用多类语言风格，凸显权威理性特征。论文提出，基于党政微博的核心价值观传播实践，需强化应用个体叙事方式，增强四类语言风格应用的协调性，提升多种话语形式的综合运用效果。在社会主义核心价值观传播路径方面，研究发现，党政微博注重将核心价值观契合中华优秀传统文化，注重将核心价值观广泛融入奋斗实践各领域，关注将核心价值观紧密指向时代问题。论文提出，各类传播路径下党政微博对核心价值观的阐释方式有待优化，应进一步加强与中华优秀传统文化内容的结合，并注重以问题为导向增强社会主义核心价值观网络传播的时代感。最后，本研究系统地提出了构建社会主义核心价值观网络传播的主要机制，即价值引领保障机制、整体协同推进机制以及网络受众接受促进机制。第一，充分彰显价值导向功能，建立起常态化传播、“情理交融型”传播、“显隐性”渗透传播机制；第二，促进各类传播要素协同发展，推动各级传播主体协同发展；第三，提高网络互动实效性，利用大数据技术精准识别受众接受度，建立以网络受众为中心的工作机制。

As the common spiritual home of hundreds of millions of people, cyberspace has become an important field for cultivating and practicing core socialist values. It has important theoretical value and practical significance for scientifically grasping the laws of network dissemination of core values, and effectively improving the effect of network dissemination of core values, by using big data methods to deeply study the dissemination practice of socialist core values on party and government microblogs. Based on the analysis and elaboration of the guiding ideology, theoretical basis and research methods of the network communication of socialist core values, the thesis proposes three core elements of the network communication of socialist core values—communication content, communication discourse, and communication path. And then, the study selects Sina Weibo as the dissemination carrier and 150 party and government Weibo as the dissemination subject, and introduces big data as the method, and constructs a three-element analysis framework for the network dissemination of socialist core values.For the research on the dissemination of core socialist values, this study found that the dissemination of the basic content of the core socialist values by the party and government microblogs showed the characteristics of overall balance, prominent focus, and gradual growth, forming a multi-subject collaborative linkage. The content and form of ideological and political education carry out the dissemination of values, and there is a close connection between the practice of Weibo dissemination and t social identity. The paper proposes that, there is a staged communication problem in the basic content of the core values of the party and government microblogs, and a certain dislocation between the communication behavior and the value preferences of the online audience, and the volume and integrity of the communication need to be improved urgently, the ideological and ideological forms are embedded in the communication also need to be optimized.In terms of dissemination of socialist core values, the study found that the party and government microblogs focus on collective narratives, pay attention to the use of a language style that integrates reason and reason, and prudently use multiple language styles to highlight the authoritative and rational characteristics. The paper proposes that, based on the core value dissemination practice of party and government microblogs, it is necessary to strengthen the application of individual narrative methods, enhance the coordination of the application of the four types of language styles, and improve the comprehensive application effect of multiple discourse forms.In terms of the dissemination path of the socialist core values, the study found that the party and government microblogs focus on making the core values in line with the excellent traditional Chinese culture, focusing on the extensive integration of the core values into various fields of struggle and practice, and focusing on closely pointing the core values to the issues of the times. The paper proposes that the interpretation of core values by party and government microblogs under various communication paths needs to be optimized, and the integration with Chinese excellent traditional cultural content should be further strengthened, and attention should be paid to problem-oriented enhancement of the sense of the times in the network communication of socialist core values.In the end, this study systematically proposes the main mechanisms for constructing the network communication of core socialist values, namely, the value guidance guarantee mechanism, the overall synergistic promotion mechanism and the network audience acceptance promotion mechanism. First, fully demonstrate the value-oriented function, and establish a normalized communication, integration of emotion and reason communication, and explicit and recessive penetration communication mechanism. Second, promote the coordinated development of various communication elements and promote the coordinated development of communication entities at all levels. Third, improve the effectiveness of online interaction, use big data technology to identify audience acceptance, and establish a working mechanism centered on online audiences.
