Scientific evaluation of the input-output efficiency of civil aviation industry to regional economy in each province or region of China is an important basis for objectively reflecting the radiation and driving effect of civil aviation industry to regional economy. This paper adopts the DEA-BC2 model to quantitatively analyze the civil aviation transportation inputs and economic development outputs of China's 31 provinces or regions from 2010 to 2019. Our findings show that the input-output efficiency of China's civil aviation industry to regional economy presents a steady increase in general, but there are significant regional differences among the seven major 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 levels and growth rates among the provinces. There are also significant differences in the efficiency level and growth rate among provinces or regions. 11 provinces or regions, including Hainan, Gansu, Ningxia, Qinghai, Inner Mongolia, Xinjiang, and Liaoning, all suffer from low levels of technical or scale efficiency, and it can be tentatively assumed that the input-output efficiency level of civil aviation industry o regional economy is low in these provinces, and this needs to be improved. Finally, this paper proposes some policy suggestion, such as increasing capital investment and rationally planning the spatial layout of key industries, to improve the input-output efficiency of civil aviation industry to regional economy. Our findings provide insights into recognizing the differences and patterns of the input-output efficiency of air transport to regional economy in China's 31 provinces or regions, with an aim to promoting the improvement of the input-output efficiency of civil aviation industry to regional economy in different regions.
