In the process of building the Digital Silk Road,Chinese enterprises dominate the construction,operation and maintenance of infrastructure related to the Digital Silk Road.In addition to conventional legal means,with the help of the market power of Chinese enterprises,the universality of industry standards,and the physical limitations of infrastructure,the Chinese government has the ability to export the digital governance rules that satisfy the needs of the countries involved as well as their own interests to the countries along the Digital Silk Road,and thus establish a digital governance order that has no formal legal form,but has the same legal effect.This construction path,named the Beijing Effect,is very different from the traditional transnational legal process of the United States and the Brussels Effect of the European Union,and helps to reveal the inner formation mechanism of the transnational legal order of the Digital Silk Road.Since the Beijing Effect is fundamentally constrained by the data sovereignty of the host country,it is necessary to strengthen the existing policy communication mechanism and introduce a new international hard law mechanism to harmonize the regulatory policies and measures of each country,so as to ensure that the construction of the Digital Silk Road is stable and far-reaching.
