China's air transport industry has long placed a premium on passengers over cargo, with airports paying far less attention to air cargo than to passenger air transport. However, due to the impact of the epidemic and the rapid economic and social development, the former has become more important than ever. The level of development of the air cargo industry is directly related to a country's influence in international trade and its right to speak in the international division of labour. In the process of promoting the overall high speed and quality development of China's air cargo industry, the regional air cargo development layout is also an important link. As an important air cargo hub in western China, the quality of air cargo services at Shuangliu International Airport is of great significance in promoting regional economic development and enhancing international competitiveness. This study aims to explore the air cargo service quality of Shuangliu International Airport, and construct a preliminary air cargo service quality evaluation index system by introducing the LSQ evaluation model and SERVQUAL evaluation scale to make an objective assessment of it. In order to reflect the scientificity and accuracy of this evaluation index system, an empirical test study was conducted in the form of a questionnaire survey. The results show that, firstly, the evaluation index system initially constructed in this paper is relatively comprehensive and can extract enough effective information; secondly, the overall quality of cargo service at Shuangliu Airport is not high, among which the evaluation score of "functional quality" in the quality of cargo service at Shuangliu Airport is the lowest; finally, on the basis of the evaluation results of cargo service quality at Shuangliu Airport Finally, based on the results of the evaluation of cargo service quality at Shuangliu Airport, the development experience of leading cargo hub airports at home and abroad, combined with Shuangliu Airport's own unique development characteristics, measures are proposed on the issue of "how to improve the quality of cargo service at Shuangliu Airport". These include strengthening the maintenance and renewal of air cargo facilities, enriching and improving the route network, and enhancing customer experience, in order to further improve the quality of air cargo services at Shuangliu International Airport.
