Abstract: The new development pattern has rich connotations and emphasizes the transformation of the economy to high-quality development. As the supply side, the“new infrastructure construction”is an important way to empower China to have a high-quality development. The demand-side reform focuses on realizing the smoothness of the economic circulation process. The implementation of the “new infrastructure construction”has to solve the problems of the previous“old infrastructure construction”in terms of institutional mechanisms, pay more attention to“the quality”(that is, investment efficiency), be sustainable, avoid dangling debt, and form corresponding future income. For this reason, the “new infrastructure construction”needs to be coordinated with the demand-side reform in the circulation of the national economy, and the two should form a benign relationship that promotes each other and has positive feedback and dynamic circulation.

Key words: new development pattern, “new infrastructure construction”, demand-side reform
