Research on Chengdu-Chongqing Airport Group Operational Efficiency Measurement and Evaluation
Chengdu-chongqing airport group is an important air transportation hub in China and an im-portant node connecting southwest China.This study aims to explore the significance of the operation effi-ciency of Chengdu-Chongqing airport group to the economic and transportation development of Chengdu-Chongqing region.Firstly,the input index and output index of Chengdu-Chongqing airport group are de-fined,the relationship between the indicators is analyzed by Kendall and Spearman correlation analysis method,and the data is processed by AHP.Then,Data Envelopment Analysis(DEA)was used to study the operation efficiency of the airport group.DEAP 2.1 software was used to solve the three models,and the operation efficiency of Chengdu-Chongqing airport group was evaluated from the aspects of static,dy-namic and Malmquist index.The results show that there is a strong positive correlation between input and output.The overall efficiency of Chengdu-Chongqing airport group is low,especially in the cargo and mail throughput,there is a serious output shortage.The efficiency gap between airports is large,and there is a problem of insufficient utilization of resources.
