This study analyzes the driving force of airside economic construction from four levels: primary influence, secondary influence, derivative influence and permanent influence. It also analyz es the dynamic relationship between the aviation industry and the construction of airside economy. In order to further research on the development of airside economic construction, this paper uses the entropy weight method to optimize the gray situation de cision making theory, and conducts research on the development and countermeasures of airside economic construction in Henan Province. According to the gray decision making effect measurement calculation, it is known that the key construction area of airsi de economy in Henan Province should be selected as H2 area, with the effect measurement score of 0.9789, the highest value. The economic effect achieved by prioritizing the development of tertiary industry or the joint development of secondary and tertiary industries in the construction of airside economy in the H2 area is the highest, with the effect measurement scores of 0.755 and 0.749, respectively.
