Core Viewpoint - The opening of the Guang-Zhan high-speed railway significantly enhances connectivity in the Guangdong-Hong Kong-Macau Greater Bay Area, reducing travel time between cities and promoting economic collaboration and development in the region [1][2][6]. Group 1: Infrastructure Development - The Guang-Zhan high-speed railway, with a design speed of 350 km/h, shortens the travel time from Guangzhou to Zhanjiang to under 1.5 hours, integrating the western Guangdong region into the Greater Bay Area's "one-hour living circle" [1][5]. - By the end of the 14th Five-Year Plan, Guangdong's railway mileage is expected to reach 6,500 kilometers, with high-speed rail extending to 3,600 kilometers, increasing the number of cities connected by 350 km/h high-speed rail to 17 [1][6]. Group 2: Economic Impact - The high-speed railway is expected to enhance the efficiency of the flow of people, goods, capital, and information, fostering regional collaboration and economic growth in the Greater Bay Area [2][6]. - The opening of the Guang-Zhan high-speed railway is anticipated to significantly boost Zhanjiang's position as a hub city in western Guangdong, facilitating the integration of high-end resources such as capital and technology [6][8]. Group 3: Regional Connectivity - The railway enhances the connectivity between the Greater Bay Area and other economic zones, including the Hainan Free Trade Port and the Beibu Gulf city cluster, promoting coordinated regional development [8][9]. - The completion of the Guang-Zhan and Shan-Shan high-speed railways will create a seamless transportation network, allowing for efficient travel between major cities and contributing to the formation of a "three-hour economic circle" along the coast [9][10]. Group 4: Future Prospects - Future plans include over 30 railway and intercity lines in the Greater Bay Area, aiming for an operational mileage exceeding 5,000 kilometers, which will facilitate a one-hour transportation circle within the area and a 1.5-hour circle to other provincial cities [7][9]. - The development of the high-speed rail network is expected to reshape the economic landscape of Guangdong, enhancing its competitiveness on a global scale and contributing to the establishment of a world-class urban agglomeration [10].
