DEA efficiency-based coupling and coordination analysis of China civil aviation industry and regional economy

Abstract

The fundamental role of the air transport sector in promoting the regional economy has become increasingly prominent due to the significant influence of the aviation hub, the international first-class aviation services, and the well-developed general aviation functions. Therefore,  it is crucial to evaluate the degree of coordination between the civil aviation industry and the regional economic level. This paper constructs the evaluation index system of civil aviation industry and regional economic development level from the input and output aspects, and develops a coupling coordination degree model for these two sectors based on the DEA-CCR efficiency model, and empirically analyzes the coupling coordination degree of the two and examines the development trends by using the data from 2010-2019. The results of coupling coordination degree of civil aviation industry and regional economy in the seven regions of China shows a steady upward trend. However, there are significant regional differences. Among them, East China and North China exhibit a higher degree of coordination, while Northwest China is in the stage of dysfunction. Using the DEA efficiency model to measure the efficiency over time can effectively classify the coupling coordination degree of different regions into stages. Analyzing the coupling coordination degree of civil aviation industry and regional economy not only enriches the research on the coordinated development of the civil aviation industry and regional economy, but also provides a new insights intothe sustainable development of civil aviation transportation. This analysis offers theoretical support and reference for the future planning of civil aviation construction, which helps to promote the coordinated development of civil aviation industry and regional economy.
