The Civil Aviation Administration has proposed implementing a high-quality development strategy for the new era of civil aviation, accelerating the construction of "Four Types of Airports" centered on Safe Airports, Green Airports, Smart Airports, and Humanistic Airports. The goal is to build modern civil airports that integrate intrinsic quality with external elegance. This strategy shifts the focus from past quantity-driven growth—emphasizing scale and volume—to quality-driven development that prioritizes efficiency and effectiveness. Among these, Smart Airports serve as the key support and implementation pathway for advancing the "Four Types of Airports" initiative.
