摘要
运用多种运输方式下的基础设施地理空间数据和OD流量大数据,识别西部陆海新通道主要港口潜在腹地和真实腹地的空间格局,评价两类腹地的空间匹配关系。结果表明:(1)西部陆海新通道主要港口两类腹地的范围大致相同,腹地内部竞争力的空间分布存在差异;(2)西部陆海新通道主要港口的潜在腹地覆盖范围较广但竞争力不强,通道对于时间价值更高的货物更具吸引潜力;(3)西部陆海新通道主要港口的真实腹地覆盖范围在运输方式间存在显著差异,公路腹地与港口邻近而铁路腹地与港口分离;(4)交通基础设施质量和运输服务水平是影响两类腹地匹配关系的重要因素,大能力运输通道匮乏导致广西和通道西侧的运输供给能力较弱,班列竞争力不足制约了川渝地区的通道运输份额。未来,应提高西部陆海新通道建设的供需匹配针对性,拓展建设中缅印度洋新通道,以进一步保障我国海外战略性关键资源的供应安全。
With the support of infrastructure geospatial data and OD traffic big data under multiple modes of transportation,the spatial pattern of the potential hinterland and the real hinterland of the main ports of the New Western Land-Sea Corridor is identified,and the spatial matching relationship between the two types of hinterland is evaluated.The results show that:(1)The scope of the two types of hinterlands of the major ports of the New Western Land-Sea Corridor is roughly the same,and there are differences in the spatial distribution of competitiveness within the hinterland;(2)The potential hinterland coverage of the major ports of the New Western Land-Sea Corridor is wide but the competitiveness is weak.The corridor has more attractive potential for freight with a higher value of time;(3)The real hinterland coverage of major ports in the New Western Land-Sea Corridor has significant differences between modes,with highway hinterland being adjacent to ports and railway hinterland being separated from ports;(4)The quality of transportation infrastructure and the level of transportation services are important factors affecting the matching relationship between the two types of hinterlands.The lack of large-capacity transportation infrastructure leads to weak transportation supply capabilities in Guangxi and the west side of the corridor.The lack of competitiveness of trains restricts the share of corridor transportation in the Sichuan and Chongqing regions.In the future,the supply and demand matching of the construction of the New Western Land-Sea Corridor should be improved,and the construction of the China-Myanmar Indian Ocean New Corridor should be expanded to further ensure the supply security of my country’s overseas strategic key resources.
