Core Viewpoint - The establishment of efficient intercity transportation networks is crucial for economic integration and cultural collaboration, serving as a key driver for coordinated urban development. The recent completion of the Suichuan to Dayu Expressway significantly enhances connectivity between Ganzhou and the Guangdong-Hong Kong-Macao Greater Bay Area, reducing travel time to 4 hours and facilitating trade and personnel movement [1][2]. Transportation Network Development - The Suichuan to Dayu Expressway, costing 24.45 billion yuan and spanning 127 kilometers, is part of a broader strategy to enhance transportation links between Jiangxi and Guangdong, with 7 cross-province expressways completed to date [1][5]. - Jiangxi and Guangdong have the highest density of expressways in the country, averaging one expressway every 50 kilometers, with plans for complete coverage of expressways in border counties [4][5]. Economic and Industrial Collaboration - The improved transportation network has led to deeper industrial collaboration between Guangdong and Jiangxi, exemplified by the "Bay Area R&D + Jiangxi Manufacturing" model, which has attracted major companies like Gree and BYD to invest in Jiangxi [1][11]. - In 2024, Jiangxi utilized 334.516 billion yuan from Guangdong enterprises, accounting for 30.52% of its total external project funding, highlighting the strong economic ties [11]. Population and Labor Mobility - The enhanced transportation infrastructure has significantly increased labor mobility, with 2.3 million workers from Jiangxi in Guangdong, and over 50,000 enterprises from Jiangxi operating in Guangdong [7]. - In 2024, Ganzhou is expected to receive 113 million domestic tourists, with 70% coming from Guangdong, indicating strong interprovincial tourism and economic interaction [7]. Future Developments - Plans for the Ganzhou-Guangzhou High-Speed Railway aim to further integrate Jiangxi into the "railway-based Greater Bay Area," enhancing connectivity and economic opportunities [8]. - The ongoing development of expressways and high-speed rail is expected to create a "dual-channel" transportation layout, facilitating even greater economic collaboration between the regions [8].
