We upgrade the Silk Road Node City 2.0（index）in this report，to identify “the Silk Road Node Cities” that with strong control power of development in the urban network along the “one Belt and one Road”. Based on the available data，we selected a total of 138 sample countries and 350 sample cities. By constructing an evaluation index system including strategic partnership，regional influence，growth leadership，and “five links”，a total of 23 important node cities were selected，as well as 19 secondary node cities and 23 general node cities. According to our research，23 important node cities are mainly located in Western and Eastern Europe，19 secondary node cities are mainly located in Eastern Europe，and 23 general node cities are mainly located in Southeast Asia and West Asia. These three types of node cities are important areas to further promote the high-quality development of the “one Belt and one Road”. In addition，we identified 100 potential node cities，mainly located in East Asia，Southeast Asia，and West Asia. We further analyze the node cities that have performed well in the field of “Five Links” to meet the specific needs of specific types of investment. At the same time，we noticed that there were obvious differences in the node functions of cities in different regions. Thus，in addition to focusing on important regions such as Eastern Europe，Western Europe，Southeast Asia，and Western Asia，we should focus on improving the connectivity of facilities in Africa and take Auckland as breakthrough point to promote the node function construction in the Americas and Oceania.
