Abstract:

【Purpose/significance】 Interdisciplinary integration is the internal logic and driving force of scientific development. Inter⁃

disciplinary research in the field of humanities and social sciences at home and abroad not only expands the boundaries of knowledge,

improves cognitive and communicative abilities, but also safeguards national security and enhances the power of academic discourse.

【Method/process】 The article sorted out and analyzed the literature topics of interdisciplinary research in the field of humanities and

social sciences at home and abroad with the help of the combined method of LDA and Word2vec, and made a comprehensive compari⁃

son of the literature topics from both synchronic and diachronic dimensions to reveal the commonalities and differences of interdisci⁃

plinary research at home and abroad. 【Result/conclusion】 The research topic that has caught sustained attention from scholars at

home and abroad is interdisciplinary education, and the hot topics that scholars have focused on in recent years are big data-based in⁃

terdisciplinary research and interdisciplinary assessment; the research field with significant differences is the field of health and medi⁃

cal care. Overall, interdisciplinary research both at home and abroad is moving in the direction of diversification, systematization and

depth

.

【Innovation/limitation】 By analyzing the interdisciplinary topics of sustained and shared concern both at home and abroad, we

put forward choices and countermeasures for interdisciplinary development in China from four aspects: "talent cultivation, evaluation

system, public services and international cooperation".
