环南海区域跨境航空网络空间结构演化

本研究收集2000、2010、2018年环南海区域各国家/地区间国际机场的跨境客运、货运航线和航班数目,探究近20年该区域跨境航空客运和货运网络的整体结构与空间格局演化特征,并综合客运和货运网络分析枢纽机场体系演化。研究发现：①该区域跨境航空网络的整体结构具有覆盖范围扩大、“小世界”效应明显和“无标度”特征显著的特点,但客、货运网络的演化存在差异。②该区域跨境航空客运网络具有明显的轴—辐组织结构特征,并呈现“多核心化”的演化趋势,而货运网络中以香港、新加坡为枢纽的轴—辐组织结构与局部性的“点—点”航空货运联系并存,尚未形成全局性的轴—辐组织结构。③该区域的区域客、货运枢纽机场发展呈现综合化、专业化趋势,香港（HKG）和新加坡（SIN）长期以来保持优势地位。

SPATIAL STRUCTURE EVOLUTION OF INTERNATIONAL AIR NETWORK IN THE SOUTH CHINA SEA REGION

The globalization process promotes the formation of a city network in which each city connects with and evolves upon interactive flows. International airlines and flights undertake cross-boundary flows of both social elite as the carriers of capital and innovation and goods with high added value. On this basis, international airlines and flights are key aspects in revealing the interactions among high-level cities and thereby becoming a subject of intense research on city networks. Applying social network and ArcGIS analysis based on a collection of data on international passenger and cargo airlines and flights within the South China Sea region in 2000, 2010, and 2018, this study examines the network structure and spatial pattern evolutions of both international air passenger and cargo networks in this transnational region. Taking air passenger and cargo networks together, Hong Kong (HKG) and Singapore (SIN) have been the two transnational airport hubs all through the 2000-2018 period, while Shanghai (PVG), Shenzhen (SZX), Taipei (TPE), and Bangkok (BKK) have emerged as the new transnational passenger and cargo airport hubs recently. Meanwhile, Singapore (SIN) has strengthened its role in the passenger network along with Kuala Lumpur (KUL), Guangzhou (CAN) and Macau (MFM), whereas Hong Kong (HKG) has played an increasingly important role in the cargo network with Chongqing (CGK), Ho Chi Minh (SGN) and Hanoi (HAN).
