Abstract: The economics research for “the Belt and Road” should focus on the "economic dimension", but its "cultural dimension" is equally important. Firstly, the economics research for “the Belt and Road” have to base on the cultural background about the multi-cultural phenomena of “the Belt and Road” countries along (or co-building countries), the Chinese cultural new thinking of “the Belt and Road” initiative itself, and the phenomena of "culture" along with "economy". Secondly, the economics research for “the Belt and Road” have to highlight the cultural ideas about the "culture symbiosis", the "path of interests", and the "Confucius improvement".

Key words: The Belt and Road Initiative, economics research, cultural dimension, cultural background, cultural ideas
