Definitely western Guangdong. First of all, the three cities of Zhanjiang, Maoming and Yangjiang in western Guangdong are connected to Guangxi Beibu Gulf in the west, Hainan &”;Free Trade Province&”; in the south and Greater Bay Area in the east; It has a certain industrial base, enough plain and hilly area, enough development space and a large input-output ratio; With convenient transportation and excellent seaport, it is promising to develop marine economy in the face of the Great South China Sea. With the construction of the Shenmao Railway and the Shenzhong Passage, and the opening of the Hong Kong-Zhuhai-Macao Bridge, it is more convenient for Zhanmaoyang to connect with Zhudong, which is helpful to undertake the westward transfer of Greater Bay Area&;s traditional manufacturing industry. The three cities in western Guangdong have a large population and a large jurisdiction area; Zhanjiang has become the sub-center of western Guangdong. Driven by the western city of Pearl River, Zhanmaoyang has the opportunity to become a new economic growth point and breakthrough in Guangdong. Secondly, the Chaoshan three cities in eastern Guangdong have natural seaports and good geographical conditions, but the docking with Greater Bay Area is not as good as Zhanmaoyang. Although the three cities of Chaoshan are connected to Fujian in the east, the south of Fujian and the west of Fujian do not belong to the Yangtze River Delta, so they can&;t enjoy the development opportunities brought by the integration of the Yangtze River Delta, and they can&;t afford to drive Chaoshan without taking back the manufacturing industry. The state has given Shantou 30 years, and Shantou has now become the sub-center of eastern Guangdong, but the livable Shantou is not a struggling Shantou. Shantou has not developed and cannot move Chaozhou Jieyang. How many years does Shantou still want to waste? Third, the mountainous area in northern Guangdong has inconvenient transportation and few plains and hills, which is not convenient for the construction of industrial parks. The landing and development of large-scale manufacturing projects are very difficult, and the urbanization construction is fragmented and unsystematic; And then to the north, docking the underdeveloped areas in Guangxi, Hunan and Jiangxi, we can&;t make progress and common development together. Therefore, the problem of low input-output ratio is common in cities in northern Guangdong, which is only suitable for developing agriculture and tourism. Generally speaking, the three cities of Zhanmaoyang have many development opportunities: Hainan has become a free trade province, and the central government is making great moves. Hainan&;s development is beneficial to Zhanmaoyang, and the cross-sea bridge is not a dream; Guangdong-Hong Kong-Macao Greater Bay Area radiates outward, and Zhan Maoyang will benefit the most; Zhanjiang is the main seaport in the southwest and the west, connecting with the Maritime Silk Road. Zhanjiang has a complete railway from west to north to east, and it is entirely possible to become a transportation hub in western Guangdong, and further become a major manufacturing and shipping city. Of course, Zhan Maoyang needs the strong support of Guangdong provincial government, Guangzhou and Shenzhen, giving Zhan Maoyang a fulcrum, and they will surely incite Guangdong.
