“Digital Silk Road” is a new globalization program to promote the joint development of mankind in the digital era. In the construction of the “Digital Silk Road”，Beijing has multiple advantages such as industrial base，technology，talents and open policy. On the other hand，Beijing faces a series of challenges. The global cyber security problem is escalating，digital protectionism is becoming more serious，the global digital trade and cross-border data flow rules are becoming increasingly competitive，and the obstacles to international cooperation brought about by the digital divide are becoming more and more evident. At the same time，our digital field of basic research，key technologies are still short. Beijing’s participation in the construction of the “Digital Silk Road” can bridge the “Belt and Road” digital divide by strengthening cooperation on “new infrastructure”，building “new windows” and promoting “Belt and Road” Digital Economy and trade cooperation. The government will build a “new rules” platform to jointly promote Belt and Road digital governance cooperation，provide security for “new talents”，and strengthen cooperation in digital talent training，build the leader of “Digital Silk Road” and the base of international digital enterprises.
