Abstract: As an important hub of the "21st Century Maritime Silk Road", ASEAN plays an increasingly important role in the "Belt and Road" initiative. By combing the mechanism of ASEAN's research on intellectual support and the “Belt and Road” initiative, the “five links”, using the method of bibliometrics and spatial analysis, respectively, the research institutions, research talents, research methods, research results, language professional training of ASEAN countries and The multi-angle analysis of the contact mechanism aims to reveal the status quo and problems of ASEAN research under the “Belt and Road Initiative” and propose corresponding countermeasures. The results show that the status quo and problems of ASEAN research intellectual support are as follows: 1)The number of intellectual support institutions facing ASEAN is small, the foundation is insufficient, and the geographical distribution is uneven; 2)The intellectual support talents are insufficiently constructed, and the domestic platform is the main one, showing “relative concentration. 3) The characteristics of macro-distribution; 3. The methods and achievements of intellectual support, the narrow focus of attention, the uneven distribution of disciplines, and the less use of quantitative methods; 4)The support of non-universal language, the lack of language academic connection, and the lack of language academic connection. There is less language talent training; 5)The lack of platform construction of the intellectual support contact mechanism, and the influence of the geo-environment-led thinking. Based on the status quo and problems of intellectual support in ASEAN, it is proposed in order to integrate and optimize the organization, attach importance to the training of talents and employment, break the barriers of disciplines, optimize the quality of results, strengthen the training and convergence of non-universal language talents, and build an effective communication platform. Targeted countermeasures are recommended.
