Abstract: The bottlenecks and blockages hindering the construction of a unified national market fundamentally stem from the incomplete nature of market-oriented reforms, and result from the obstruction of the old administrative management and control mechanisms. The blueprint of “five unifications and one openness” is the government’s specific path for advancing the construction of a unified national market. The key lies in the consistency of rules and policies and the uniformity of behavioral standards. Currently, in building a unified national market, there is an urgent need to break through various forms of institutional and hidden barriers manifested as “the main gate stays open, but the small gates are locked” in market access, and substantive progress in openness and reform oriented towards “zero barriers” must be advanced. Competition law is the fundamental law regulating the market economy and anti-monopoly law enforcement is a powerful tool for promoting the construction of a unified national market. The credit economy is an important component of optimizing market rules, competitive order, and the market environment in building a unified national market, and constructing a credit economy system is a key focus for the government’s proactive role in building a unified market.

Key words: unified national market, market-oriented reform, rule unification, institutional barriers, anti-monopoly law enforcement, credit economy
