Abstract: With the continuous promotion of the comprehensive digital transformation, the reverse digital risk has become an important issue that must be paid attention to in the field of emergency rule of law. From the global samples of reverse digital emergency rule of law, both primary digital disasters and secondary digital disasters are important manifestations of reverse digital risk, and bring about the "de bureaucratic" and "weak public welfare" transformation of traditional emergency rule of law. Facing the risk of reverse digitalization, China's emergency rule of law also faces the problems of publicity and absence of administrative power of reverse digitalization risk, the conflict between diversification of emergency response methods and emergency objectives, the digital vulnerability and the systemic problems of emergency rule of law. Therefore, under the dual requirements of comprehensive digital transformation and reverse digital risk prevention and control, China should establish a new "public private law integration" emergency rule of law, do a good job in the adjustment of organizational law and behavioral law of emergency management, and improve the reverse digital risk emergency plan, so as to promote the modernization of emergency management system and capabilities.
