Visualization and Analysis of Domestic Research on Language Economics based on Citespace Knowledge Mapping

Linguistic economics is a cross-discipline of linguistics and economics, which adopts the theories, methods and tools of economics to study language and speech behaviours as universal social and economic phenomena, and it is an integrated study of language and economic issues, which transcends the limitations of the previous sub-divisions and reflects a new paradigm of contemporary scientific exploration. However, the review and analysis of related research progress in China is not sufficient. Therefore, based on the theory of bibliometrics, this paper takes the literature related to linguistic economics in the core journals of China Knowledge Network (CNN) CSSCI and Beida as the object of research, and analyses the year, author, institution, and keywords of the literature visually with the help of the CiteSpace Knowledge Mapping tool, in order to explore the current situation of the research on linguistic economics and the hot frontiers of the research in China, with a view to providing a good basis for the subsequent research.In particular, in terms of multimodal information fusion, geospatial analysis, and the combination of language industry and tourism, it can directly guide the construction of Guilin case corpus and the design of application scenarios. The results show that: (1) From the annual trend of the number of articles published, the overall development is slow and unstable, except for the golden period of development, which is booming. (2) From the perspective of the authors, among them, Huang Shao'an, Zhang Weiguo, Su Jian and Liu Guohui are the leaders in the field of linguistic economics in China, and the four of them are in a relationship of master and apprentice, with close co-operation. (3) From the perspective of issuing institutions, the position in the field of language economics is higher education institutions, and the key position is in Shandong University. (4) From the point of view of research hotspots, ‘language industry’, ‘language’, ‘language economy’ and so on have been widely and persistently concerned. (5) From the perspective of research trend, ‘human capital’ has great potential for development in recent years.
