中国修地铁最慢的城市，就它了

Core Viewpoint - Dongguan's long-awaited Metro Line 1 has finally opened, marking a significant milestone for the city and its integration with the Greater Bay Area, yet the city's metro construction lags behind its economic status and that of similar cities [2][3]. Summary by Sections Metro Line Development - Dongguan's Metro Line 1 has been in development for over ten years and has now reached a total length of 95.2 kilometers, but the city still trails behind peers like Suzhou, Foshan, and Wuxi in metro construction [2]. - The opening of Line 1 is crucial for the interconnectivity between Guangzhou and Shenzhen, enhancing the overall transportation network in the Greater Bay Area [2]. Economic Context - Dongguan is recognized as a significant city with a robust economic growth trajectory, particularly in sectors such as smartphones, industrial robots, and new energy batteries [3]. - Despite its economic stature, Dongguan's metro construction is notably slow, with only two lines operational in nine years, highlighting a mismatch between its economic capabilities and infrastructure development [2][3]. Challenges in Metro Construction - The natural conditions in Dongguan, characterized by a complex geological environment, pose significant challenges for metro construction, including issues related to subsidence and groundwater [4]. - The city's governance structure, which is a "direct management" model without districts, complicates unified planning and decision-making for metro projects, leading to inefficiencies [6][7]. Financial Constraints - Dongguan's financial autonomy is limited, with a significant portion of tax revenue allocated to central and provincial governments, restricting local funding for large infrastructure projects [8]. - The total investment for Line 1 is approximately 379.8 billion yuan, with the government required to contribute 40%, leading to substantial long-term financial pressure due to reliance on loans and public-private partnerships [8]. Governance and Future Outlook - The current governance model has both advantages and disadvantages, allowing for local autonomy but lacking in coordinated city-wide planning, which is essential for large-scale projects like metro construction [9]. - There is a need for Dongguan to find a balance between local development autonomy and centralized planning to improve infrastructure development and address the slow pace of metro construction [9].
