| With the rapid development of civil aviation transportation in China,the demand of air travelers is gradually increasing,and the airport density is constantly increasing.Under the background of the rapid social and economic development in our country,the comprehensive traffic between the cities in the region has been developing continuously,promoting the formation of a metropolitan area.Airport land transport continues to improve and expand to multi-airport system based on the regional metropolitan system prototype in China initially formed.Civil aviation transport network constructed with hub airports as the air transport and metropolitan area are constantly complicated.The competition in airports is also transformed from competition among airports in different regions to competition between airports and airports in the same area.competition.Regional and market characteristics determine the degree of competition and synergy in multi-airport systems.The effective competition and coordination among multiple airports in the region is the key to realize the efficient operation of multi-airport system.The scientific and rational positioning of airport functions is the starting point to realize multi-airport system operation.Airport functional orientation is mainly determined by the choice of airport passenger behavior.The behavior of air passenger airport selection is affected by many factors,which are embodied in the comprehensive competitiveness of the airport.However,its performance in the field of space geography is the airport radiation field.Therefore,from the perspective of passenger choice behavior,it is an important way to solve the functional orientation to construct the comprehensive competitiveness of the airport and analyze the airport competition effect in the study area.In this paper,using the theory of space interaction and competition destination model,the introduction of Co-integration coefficient reflects the influence of the market environment on the airport radiation field and builds a new model of multi-airport radiation range based on the Wilson model.Based on the sensitivity analysis of the influence of Co-Incident Coefficient(Co-Incident Coefficient)on the radiation field of the airport in the region,the co-opetitive strategies in different environments are suggested for airports with overlapping radiation coverage from the perspective of multi-airport synergy.Based on the established analytical model,taking the 14 airports in the Yangtze River Delta multi-airport system as an example,the relevant data of 2016 are selected to study the multi-airport radiation field in the Yangtze River Delta region and its sensitivity to changes in the co-occurrence intensity.The results show that there are five airports in the Yangtze River Delta multi-airport system with high radiation intensity.The radiation fields of Shanghai Hongqiao Airport,Ningbo Lishe Airport and Hangzhou Xiaoshan Airport overlap.Considering the synergetic problem of multiple airports,the changing trends of the elastic values of the three airports are observed.At the same time,the co-opetition relationships among the three airports in the system are analyzed for different competing effects. |
