As an important part of consolidating the people’s democratic regime and building a new democratic society, constructing a new economic order after the liberation of cities includes the following aspects: establishing a financial order with RMB as the core and stabilizing the social and economic operational environment, coordinating the internal contradictions of enterprises and building a new type of labor management relationship, and establishing a standardized and unified economic development environment by adjusting public-private partnerships and industrial and commercial taxes. Chen Yun is the main organizer of implementing the new urban economic order, which has not only ended the chaotic economic order at the beginning of urban liberation, but also laid the foundation for a new socialist economy.
