中文摘要：

大多数机场亏损严重,设施资源闲置浪费现象突出等问题引发了长三角机场建设密度是否过高的争论.基于这种背景,本文通过解析系统协调发展机理,在耦合度、协调度和综合发展指数模型基础上,构建了复合系统耦合协调发展度评价模型,并对长三角多机场复合系统进行了实证分析.结果表明：长三角多机场复合系统中,耦合协调发展度较高的机场占75%,耦合协调发展度与机场等级存在较强关联性;机场规模等级越高,其与经济的耦合协调发展度越好,大型综合枢纽机场普遍高于中小型机场;地区经济发展水平的高低是影响机场区域耦合协调发展程度的重要因素,经济发展水平越好的地区,机场与经济的耦合协调发展度越高.

英文摘要：

Most airports serious loss and stressed waste of facility resources and other issues lead to the controversy of whether the Yangtze River Delta airport construction density is too high. Based on this background, this paper analyzes the mechanism of system coordinated development, after constructing the degree of coupling, coordination degree and integrated development index model, composite system coupling coordinated development degree evaluation model is investigated with the Yangtze River Delta multi-airport and economic system as case study. The results show that a high degree of coordinated development of airports accounted for 75%, coupled with airports there is a strong correlation between coordinated development degree and airport scale. The airport with higher size has better coordination with economic development.Large-scale integrated hub airports is generally higher than the small airports. The level of economic development is an important factor affecting the degree of coupling coordinated development, the better the level of regional economic development, the airport and the economy more coordinated development degree coupling high. The region of better economic development level has higher coupling coordinated development degree between airport and economy.
