The rapid expansion of high-speed rail (HSR) has significantly improved spatial accessibility and connectivity efficiency, and affected the reallocation of spatial resources and regional economic sustainability. This study examined 40 prefecture-level (or above) cities in the Yangtze River Delta (YRD) region, and explored the evolution process of the HSR service network and its impact on the sustainability of economic development. The research results show that: (1) From the perspective of intercity travel time and service connections from 2009 to 2018, the rapid development of HSR has increased the city’s rail accessibility by about 50%, leading to closer intercity connections. (2) There are obvious regional differences in the effect of HSR on urban functional levels and the intensity of inter-city connections. Compared with 2009, the central cities play a greater role as transportation hubs in 2018, creating a significant Matthew effect of accumulated advantage. (3) The distribution pattern of regional urban intensity index is uneven, and the difference in urban intensity index in 2018 is significantly greater than that in 2009. (4) The evolution of the HSR network has significantly affected regional economic development, especially the development of tertiary industry, and increased the polarization of economic development in the YRD. This research can provide a certain reference for regional sustainable development.

Abstract The rapid development of e-commerce has greatly promoted the development of the modern logistics industry. The application level of e-commerce and the application status of modern logistics largely determine the development of regional economic structure in a region. Under this circumstance, it is particularly important to comprehensively strengthen the research and analysis of the impact of e-commerce and modern logistics on the regional economic structure and scope, and promote the coordinated development between each other. As one of the most developed regions in China, the Yangtze River Delta region has achieved certain achievements in the development of regional logistics industry and e-commerce, and plays an important role in the process of regional integration in the Yangtze River Delta. Therefore, this paper takes the Yangtze River Delta as the research object, and empirically analyses the development status of the logistics industry and e-commerce in the Yangtze River Delta region and its contribution to regional economic growth. On this basis, it puts forward countermeasures to further increase the contribution of the logistics industry and e-commerce in the Yangtze River Delta region to economic growth. This will provide a reference for the construction of a coordinated regional logistics-e-commerce system and the realization of regional economic integration in the Yangtze River Delta region.

<em>The role of high-speed rail network in the metropolitan areas is becoming more and more important, which has become one of the main ways of the city personnel contacts. This paper mainly uses the social network analysis method to revamp the six national metropolitan areas: metropolitan area of the middle reaches of the Yangtze River, metropolitan area of Hachang, metropolitan area of Chengyu, metropolitan area of Yangtze River Delta, metropolitan area of Zhongyuan, metropolitan area of Beibu Gulf make a comparative analysis. The macroscopic and microscopic angles are used to calculate and compare the overall network characteristics, centrality, core-periphery structure and cohesion subgroups. It is mainly due to the fact that the high-speed rail network structure of the six major metropolitan areas needs to be improved. Metropolitan area of the middle reaches of the Yangtze River and metropolitan area of Zhongyuan are relatively good the integrity and the connectivity. Metropolitan area of Yangtze River Delta is the highest utilization rate of resources. Metropolitan area of Hachang is the highest network density. Metropolitan area of Chengyu is outstanding between core and periphery. Metropolitan area of Beibu Gulf network of organizations is broken. Therefore, when layout of high-speed rail infrastructure, we should consider the high-speed rail network resource utilization, balance high-speed rail traffic within the metropolitan areas, thus enhancing the city’s high-speed rail accessibility and convenience.</em>
