Since May 2015，when the connection of the ‘Belt and Road Initiative’ and Eurasian Economic Union have begun，China and Russia have deeply promoted the alignment of the development strategies and the construction of the BRI，on the basis of the economic cooperation achievements that have been achieved between them. The alliance builds docking cooperation，then develops a higher level and deeper economic cooperation relationship in Eurasia，to effectively achieve the optimal allocation of capital，resources，and labor between the eastern and western areas of Eurasia. As the leader of world economic growth，China has its own advantages in production capacity，capital，development model，and technology parts. Through the BRI link to the Eurasian Economic Union，China will transform these advantages into market cooperation superiority，and explore the path of economic growth with Eurasian countries. Shanghai is the vanguard of China’s reform and opening up. It is also the pioneer of innovation and development. Consequently，General Secretary Xi Jinping proposed to build the China（Shanghai）Pilot Free Trade Zone into a bridgehead that serves the country’s BRI construction and promotes the market to the world. During the practice of the BRI which connecting China with the Eurasian Economic Union in recent years，the function of Shanghai that as a hub for promoting the cross-border flow of market elements and the efficient allocation of resources has become more obvious. This is reflected in the condition that Shanghai has become the hub of the Sino-Russian Polar Silk Routine and Eurasian continent corridors in economy and transportation area，which relies on its superior geographical advantages and complete infrastructure. Moreover，Shanghai is also embodied as a model for gradually developing and opening up Eurasian countries.
