厘清粤港澳大湾区相关研究主题的发展脉络,把握未来研究热点,对于深入推进大湾区研究、充分发挥决策支撑作用,具有重要参考价值。利用CNKI数据,基于Citespace可视化文献计量分析,采用LDA主题模型提取关键词,挖掘出文本隐含的研究主题；结合DTM主题模型,分析了不同主题内容的演化过程。结果表明,粤港澳相关研究主题主要集中于经济合作、协同治理、人才培养、环境保护、产业升级、旅游与文化六大方面。其中,经济合作和协同治理是目前研究关注的重点,人才培养和环境保护是今后主要研究趋势,且相关内容呈现不断细化特征。

Building the Guangdong-Hong Kong-Macao Greater Bay Area into a world-class urban agglomeration and an international scientific innovation center is a major strategic decision of China. Clarifying the development context of related topics and grasping future research hotspots has reference value for the formulation of future policy plans. The data in this paper comes from CNKI Database. On the basis of using CiteSpace for bibliometrics, the LDA model is used to extract Keywords, and the research topics implied in the text are mined; combined with the DTM model, we also analyze the evolution process of different topics. The results show that the themes of Guangdong-Hong Kong-Macao related research are divided into six categories: economic cooperation, collaborative governance, talent training, environmental protection, industrial upgrading, tourism and culture. Economic cooperation and collaborative governance are the focus of current research. Talent training and environmental protection it is the main research trend in the future, and the relevant content shows the characteristics of continuous refinement.
