Driven by the regional integration, intercity economic complementarity and cooperation are enhanced in the context of megalopolization. Due to the increasing interaction and intensified connection between cities, this study attempts to investigate the impact of megalopolization on intercity human mobility from the perspective of complementary employment composition. The variation of differences in the composition of employment by industry sector between cities is identified through socioeconomic statistics in the recent decade. By using passenger flow data generated from ticket sales records, this study explores how economic complementarity affects high-speed rail (HSR) volume considering spatial dependence in megalopolises. The results show that HSR volume tends to be higher between cities with more distinct employment composition, and it is consistent with the existing studies that population size and economic output are positively correlated to the HSR passenger demand. Finally, the implication of different economy planning strategies is assessed to further highlight the interdependence between regional economic patterns and transportation activities.

在区域一体化的推动下，城市间经济互补与合作在大都市化背景下得到加强。由于城市之间的互动越来越多，联系越来越紧密，本研究试图从互补就业构成的角度研究大都市化对城市间人口流动的影响。近十年来，通过社会经济统计数据确定了城市之间按行业部门划分的就业构成差异的变化。通过使用从售票记录生成的客流数据，本研究探讨了经济互补性如何影响考虑到大都市空间依赖性的高铁 (HSR) 运量。结果表明，高铁运量在就业构成更明显的城市之间往往更高，与现有研究一致，人口规模和经济产出与高铁乘客需求呈正相关。最后，评估不同经济规划策略的含义，以进一步突出区域经济模式与交通活动之间的相互依存关系。
