摘　　要：运用潜在狄利克雷分配(LDA)模型对中国知网“百年未有之大变局的中国经济”专题库里的文献摘要进行主题挖掘,同时借助社会网络分析对发文机构合作网络的关系特征与位置特征进行分析。结果表明:研究主题丰富,研究内容与时俱进,研究方法多采用客观数据开展影响因素、作用效应及发展路径等内容的实证分析;存有5个核心机构,机构合作不足且相对封闭,产学政研合作不够深入,整体呈现出“小聚集、大分散”特点。基于此,未来中国经济研究可以从开展前瞻性研究、均衡研究注意力以及加强多元主体合作3方面进行展望。Latent Dirichlet allocation(LDA)model is used to explore the literature abstracts in China National Knowledge Network Infrastructure’s‘China’s Economy in A Century of Great Changes’thematic database.The relationship and location characteristics of the cooperation network of publishing institutions are analyzed with the help of social network analysis.The results show that the research topic is rich,the research content keeps pace with the times,and the research methods mainly use objective data to carry out empirical analysis of influencing factors,effects and development paths.There are 5 core institutions,the institutional cooperation is insufficient and relatively closed,the industry-university-government-research cooperation is not deep enough,and the overall show the characteristics of‘small gathering and large dispersion’.Based on this,China’s economic research in the future can be carried out from the perspective of forward-looking research,balanced research attention and strengthen multi-agent cooperation.
