Research on the Input-Output Efficiency of the Civil Aviation Industry to the Regional Economy in China Based on DEA Modeling

Abstract

Scientific evaluation of the input and output efficiency of civil aviation industry and regional economy in each region of China is an important basis for objectively reflecting the radiation and driving effect of civil aviation industry on regional economy. This paper adopts the DEA-BC² model to quantitatively analyze the civil aviation transportation input and economic development output data of 31 provinces in China from 2010 to 2019. The results indicate that the efficiency level of China's civil aviation industry to regional economic inputs and outputs shows a steady increase in general, but there are significant regional differences among the seven regions. The levels of comprehensive efficiency, pure technical efficiency and scale efficiency are characterized by a gradient decrease from the coastal areas of East China, North China, and Central and South China to Southwest China, Northeast China, Northwest China, and inland Xinjiang, and there are significant differences in the efficiency value levels and growth rates among the provinces. There are also significant differences in the level and growth rate of efficiency value among provinces and regions. Finally, based on an analysis of the results, this paper proposes some protective measures, such as increasing capital investment, rationally planning the spatial layout of key industries and strengthening the interaction and cooperation among industries, for the input-output efficiency of the civil aviation industry to the regional economy.
