Abstract:In the cyberspace,digital media play an increasingly important role in promoting the interaction and intermingling of various ethnic groups and forging a strong sense of Chinese nation.By analyzing the impact of digital media on the all-dimensional intermingling and integration of various ethnic groups in cyberspace, we detect the adverse effects of digital media on the forging of a sense of community among Chinese ethnic groups by studying online citizens,media platforms and digital governments and the following legal regulations, and finally propose some legal suggestions:we should improve publicity of the rule of law and education system for online citizens to forge a sense of community among Chinese ethnic groups,build a legal system for the promotion of a sense of community among Chinese ethnic groups,and strengthen the digital governance for the promotion of a sense of community among Chinese ethnic groups,so that digital media can play a positive role in forging a strong sense of the Chinese nation in cyberspace.
