Abstract: From the perspective of transportation infrastructure construction, this paper measured the Gini coefficient of transportation in the east, central, west regions in China, evaluated the fairness of transportation, and studied the relationship between transportation fairness and regional economic development by establishing a coupling coordination model. The results showed that the Gini coefficient of transportation in the whole country and the three regions of east, central and west showed that a general downward trend, which is in the stage of highquality development with middle average to high average degree; the coupling and coordination development of the two systems are well developed, but the coupling and coordination of the western region is still backward.

Key words: transportation equity, Gini coefficient, regional economic development, coupling coordination degree

摘要： 从交通运输基础设施建设角度出发，测算我国及东、中、西三大区域的交通运输基尼系数，评价其公平性。建立耦合协调度模型，研究交通运输公平性与区域经济发展之间的关系，并利用2003—2017年的省际数据实证分析。结果表明，全国及东、中、西三个区域的交通运输基尼系数整体呈下降趋势，处于从比较平均向高度平均过渡的优质发展阶段；交通运输公平性和区域经济发展两系统的耦合协调性发展势态良好，但西部地区的耦合协调性仍然落后。
