2023 marks the 10th anniversary of the the Belt and Road Initiative. Over the past 10 years, the “the Belt and Road” initiative has become an important platform to promote the construction of a community with a shared future for mankind, from concept to action，and from vision to reality. Analyzing the report of European think tanks can give a glimpse of Europe’s overall understanding of the “the Belt and Road” construction in the past ten years, which is of great significance for promoting the next stage of the “the Belt and Road Initiative”. This paper selected 13 539 texts related to the “the Belt and Road” published from around 2013 to September 2022 by 212 European think tanks in the 2020 Global Think Tank Index Report jointly released by the Think Tank Research Program of the University of Pennsylvania (TTCSP) and Bruegel Think Tank for text mining, and discussed the emotional tendencies and agenda setting of the “the Belt and Road” initiative of Europe’s leading think tanks, observing the perspectives and positions of European public decision-making and public opinion under the “revolving door” mechanism from a side perspective. While summarizing the potential opportunities and challenges faced by the initiative in the European promotion process, this paper provided data support and reference for how to effectively improve the image of the initiative in the overseas public opinion environment. The study found that although European think tanks hold a slightly positively neutral attitude towards the Belt and Road Initiative on the whole, there are significant regional and national differences. Think tanks in central and eastern European countries hold the most positive sentiment, while the views of their counterparts in northern Europe and Baltic countries are the most negative, and think tanks in western Europe and southern Europe hold the most neutral position. Through topic modeling, this paper further finds that the narrative of common economic prosperity is representative in the mainstream European public opinion circle.
