Abstract:

Based on the new trends of urbanization in the world and China as well as Japan's construction of the high-speed transportation network between Tokyo and Osaka metropolitan areas, this paper focuses on strategic layout issues and the development of the state transportation network in the future China. The paper recognized that the world urbanization is manifested in three characteristics: development of global cities and global city-regions,re-prosperity of metropolitan areas and urban giantization and new mega-regions. In Japan, three major metropolitan areas (Tokyo, Osaka and Kyoto) are undergoing polarization development. While implementing the functional restructuring of the Tokyo metropolitan area for industrial development, two new territorial development plans have been launched for the construction of the world’s largest super-mega-region. In China 2018, the total population has peaked and entered a downward channel. However, China’s urbanization process is still in an accelerated period. In the near future, the national urban system will develop from the current “three verticals development axes and two horizontals development axes” to the “four vertical development axes and five horizontal development axes”. On the whole, in the future, although the demand for infrastructure will be at a standstill stage, the infrastructure construction based on large traffic will be splendid in some national strategic zones and potential growth zones, as well as for meeting development of new technologies such as 5G, self-driving cars, et al. These regions maybe become new highlight areas such as the Yangtze (changjiang) River Economic Belt, the Guangdong, Hong Kong and Macao Bay area, the Yangtze River Delta Higher Quality Development Integration Zone, the Beijing-Tianjin-Hebei Urban Agglomeration toward the Beijing World City Construction, Northeast China and Shandong Province. Based on new trends of urbanization, China's transportation network strategic should focus on following three aspects: 1) the state transportation networks should be encrypted in some national strategic zone; 2) Planning and construction of the driverless highway in advance; 3) Pay attention to the development of transportation infrastructure to stimulate the development of potential growth zones. For example, the eastern and western high-speed passages in the Northeast, the high-speed traffic interconnection between Shandong and Jiangsu, Henan and Hebei, and Northeast China. In addition, some other high-speed traffic lines have also become more and more important for the development of the Central China and the western China, for example, the line between Urumqi and Kashgar, Yinchuan-Lanzhou-Xining, Xining-Chengdu, Chongqing-Guiyang-Nanning-Qinzhou, Chengdu-Lhasa, Kunming-Baoshan, Yinchuan-Xi'an-Wuhan-Nanchang-Fuzhou-Taipei, Hefei-Nanchang-Zhangzhou, etc..
