| 中文摘要: |
| 探讨政务微博反诈宣传信息的空间分布规律，揭示反诈宣传主题在地理空间上的聚集模式及其作用机制。以政务微博中反诈宣传博文为研究对象，采用Word2Vec词向量模型训练及扩展原始词汇，基于LDA主题模型提取政务微博反诈宣传主题，计算每个地区的相对主题强度；运用空间自相关分析方法评估不同反诈宣传主题的空间聚集性及区域差异，识别当前政务微博反诈宣传策略，并结合公众参与度揭示政务反诈宣传的区域传播策略。研究发现：政务微博反诈宣传主题具有多样性及针对性特征，公众对行动导向型主题的关注度更高；不同主题在地理空间上呈现显著的聚集特征，聚集区域主要集中于中部和东部地区；政务微博反诈宣传呈现出“系统性宣传”与“区域针对性宣传”相结合的模式，其中结合区域实际的针对性宣传更易引发公众关注与互动行为。 |
| 英文摘要: |
| This paper aims to explore the spatial distribution patterns of government microblog anti-fraud propaganda information, and to reveal the spatial clustering patterns and underlying mechanisms of anti-fraud propaganda themes in geographic space. The Word2Vec word vector model is applied to train and expand the original vocabulary, and then the LDA topic model is employed to extract anti-fraud propaganda themes from government blog posts and compute the relative topic intensity for each region. Spatial autocorrelation analysis is applied to evaluate the spatial clustering and regional differences of various anti-fraud propaganda themes, identify current government microblogging strategies for anti-fraud publicity, and uncover the spatial communication strategies in conjunction with public engagement levels. The study finds that the theme of anti-fraud propaganda on government microblog has diversity and specificity, and the public pay more attention to the action-oriented themes. Different themes show significant spatial clustering in geographical space, mainly concentrated in the central and eastern regions. The anti-fraud propaganda of government microblog presents a combination of “systematic propaganda” and “regional targeted propaganda”. Among them, targeted propaganda combined with regional reality is more likely to trigger public attention and interactive behavior. |
