Under the promotion of global economic integration and the rise of e-commerce,China’s air cargo transportation industry is developing rapidly.It is very important to use what standard and method to express the development level of air freight accurately and quantitatively,which affects the direction and focus of air freight development in China.In order to solve this problem,based on the idea of big data,this paper systematically analyzes the development of China’s air cargo,and calculates the development index of China’s air cargo.Based on python programming language,this paper designs a crawler system of China air freight development index,which includes two parts: URL module and content download module.It performs web page request,web page analysis and data storage,and establishes a text information database of China air freight development index.Based on the existing literature research,the connotation and characteristics of air cargo and the development trend of China’s air cargo are clarified.According to the basic principles of index index system construction,combined with high-frequency keyword statistics,and based on LDA subject model analysis,the index system of China’s air cargo development is constructed to reflect the comprehensive level of China’s air cargo development.Using the high frequency key words frequency and entropy method to determine the index index system weight,the dimensionless original data are weighted,and five classification indexes of China’s air cargo development index,safety index,service index,security index,economic index and efficiency index are obtained.The research shows that the development index scores of China’s air cargo industry in the past 10 years are generally on the rise,mainly divided into three stages.Based on the analysis of China’s air freight development index,this paper puts forward relevant suggestions.
