A Study on the Classification and Development Stages of Regional Aviation Hubs in China Based on Network Value and Place Value

Abstract

To scientifically identify disparities in the development levels of regional aviation hubs and to ensure a rational alignment between hub resources and market demand, this study evaluates 29 regional hub airports in China. First, an evaluation index system is constructed incorporating both network value and place value dimensions. The entropy weight method is then applied to determine the weights of the indicators and to calculate the respective value scores for each airport. Subsequently, the elbow method is employed to determine the optimal number of clusters, and hierarchical clustering is utilized to classify the 29 airports into three distinct categories: highly developed, moderately developed, and lowly developed regional hubs. Finally, tailored strategic recommendations are proposed: highly developed hubs should strengthen international connectivity and establish high-frequency express routes; moderately developed hubs should expand hinterland integration through trunk-feeder networks; and low-developed hubs should focus on aviation-tourism synergy by promoting premium tourist routes.This study classifies hub airports from the dual perspectives of network value and place value, revealing a pyramid-shaped hierarchical structure of development among regional hub airports in China, thereby providing a theoretical foundation for the differentiated development of hub airports.
