Ministry of Finance, Ministry of Transport: Hub cities should focus on clearly defining the key categories of goods with large circulation scale or strong strategic support on the main skeleton of the national comprehensive three-dimensional transportation network in the local area.

Key hub cities should focus on clarifying the key types of goods in the local area that have a large circulation scale on the main framework of the national comprehensive multi-dimensional transportation network or play a strong role in supporting national strategies. Around the key types of goods, the industrial chain and trade chain should be combed to analyze the comprehensive transportation demand. Following the principle of "what is lacking, what should be supplemented", efforts should be coordinated to promote the "hard connection" of various transportation modes infrastructure and equipment on major channels, the "soft connection" of rules and standards and services, and the establishment of a sound integrated operation mechanism. Specifically, focus should be placed on filling the gaps in the weak links of the comprehensive transportation chain, strengthening the construction and information sharing of multimodal transport facilities and standards, and implementing tailored measures to enhance the multimodal transport function and development efficiency of major freight nodes.
