Robustness Study Of Air Cargo Network In Central And Southern China Region Based On Complex Network Theory

As an important node in the aviation network,air cargo network is an important channel for national and regional participation in international competition and economic exchanges with the whole world.And as an important strategic component of regional economic integration,air cargo network can not only satisfy the increasing air transport demand in our country,but also can promote our country's international competitiveness of a civil aviation enterprise.With the development of economy,the range of air cargo network radiation is becoming more and more extensive,and the structure is becoming more and more complex.Accordingly,the corresponding risks also come with it.Therefore,the basis of managing and constructing the aviation network is understanding and running the air cargo network better.Civil aviation cargo of central south area throughput of more than 1/4 national cargo throughput,which volume is huge,therefore,the study of air cargo network in the region can better manage and avoid risks.Based on the Complex Network Theory,this paper chose central and southern areas of civil aviation as research object and carry out an empirical study of Chinese central and southern region air cargo network structure from aspects as follows: network structure characteristics,hub centralization level and network robustness.It shows that central and southern areas of civil aviation is a small world network,airport value and cargo throughput and flights are positively related,which indicates larger airports are more frequent with adjacent airports,the cargo throughput is also greater.And through the analysis of the centralization level,it is concluded that the central degree of Haikou Meilan airport is the highest.After simulation of central and southern areas of civil aviation air cargo network robustness,it finds that the risk of paralysis facing air cargo network under deliberate attack is greater than that of random attack and we put forward some suggestions for improvement.Research on network structure,centralization level and network robustness are of certain theoretical and practical significance for people to understand the structure characteristics of air cargo network,analyze the change of network,and guide the operation and management of aviation network.
