At the same time, in the research and formulation of policies for the development of big data, we need to break Ideological constraints to advance with the times and advance with the Internet; need a strong centralized unified command and coordination mechanism; need to handle the dialectical relationship between development and security; and actively balance the responsibility and responsibility of global governance.
