There are three main reasons why Guangzhou will not build a subway to Qingyuan in 20 years: First, the current development direction of Guangzhou-Qingdao integration is to develop towards their respective division of labor, and part of Guangzhou&;s production capacity will be transferred to Qingyuan to boost Qingyuan&;s economic development. At present, the traffic from Guangzhou to Qingyuan is also very convenient. There are lines such as Guangqing, Guangle and Beijing-Zhuhai on the expressway. At present, there is a ring expressway network in the Pearl River Delta, such as Foqingcong, which is under construction. In addition, there are many national and provincial highways connecting Guangqing and Qingyuan. It can be said that the current highway construction between Guangqing and Qingyuan can meet the current needs. Second, in terms of intercity rail transit, the first phase of Guangqing Light Rail has been completed, and it is very convenient for Qingyuan to enter Guangzhou Huadu and White Airport. The second phase of Guangzhou-Qingdao Intercity will also be built, which will go directly to Guangzhou Railway Station, and the access time between Guangzhou and Qingdao will be greatly shortened in the future. In addition, the Beijing-Guangzhou high-speed railway connects Guangzhou and Qingyuan, and there are many pairs of trains going back and forth every day, which can meet people&;s needs. Third, the subway is a city&;s internal construction, which is different from intercity. The subway construction in both places requires that both of them must meet the subway construction standards. Guangzhou subway construction can be completed until the handover of Guangzhou-Qingyuan, but it must be approved by the State Council. the State Council needs to evaluate whether Qingyuan meets the standards for opening subways before Qingyuan can be built. Obviously, Qingyuan can&;t meet the standards for direct subway construction at present. Some people will mention the Guangfo subway. In fact, the Guangfo subway is established in two different cities, and the Foshan section of the Guangfo subway is Foshan Metro Line 1. The Guangzhou Metro Line 7, which goes directly to Shunde, was built with the approval of the State Council. In the early days, in order to build urban rail transit through Guangzhou, Nanhai could only lower the standard and build trams with right of way, but this kind of trams can be said to be subway-like, which is also very convenient. Based on the three reasons, it can be said that Qingyuan can&;t do Foshan financially at present, and it is impossible to build natural subways and similar subways.
