Abstract: High-quality development is the primary task of building a fully modern socialist country and has the basic attributes of
both value rationality and instrumental rationality, which are two dimensions of "human rationality". In the dimension of value
rationality, we pay attention to the value-oriented issues of promoting high-quality development. We hold that putting people first,
implementing the new concept of development and realizing common prosperity for all people are its value orientations, guiding
principles and development destinations. In the dimension of instrumental rationality, we are concerned about the practice-oriented
issues of promoting high-quality development. We believe that adhering to the Party's overall leadership, deepening the supply-side
structural reform and building a new development pattern are its leadership system, main line of work and strategic base point. Value
rationality and instrumental rationality contained in high-quality development are a dialectical unity. Value rationality provides value
guidance in action for the instrumental rationality of realizing high-quality development, while instrumental rationality provides
concrete path support for the value rationality of realizing high-quality development.

Key words: high-quality development, value rationality, instrumental rationality
