中国经济社会发展进入新发展阶段，意味着交通运输由高速发展全面转向高质量发展。从发展定位、功能作用、主要矛盾、发展重点、供给能力、服务水平、技术条件、制度体系等维度研判，交通行业生产力水平已经取得系统性突破，步入了由交通大国向加快建设交通强国进军的阶段性跨越。指出新时代背景下，交通运输迈向高质量发展呈现新的宏观特征，体现在：交通运输供需基本面持续旺盛，具备抢占科创高地的比较优势，客货运输需求呈现分布广尺度、结构复杂性和层次多样性，资源、资金等要素投入趋紧，新发展格局下运输格局变化不确定性加大，基本国情决定了运输结构性问题将长期存在。提出在新的起点上推进交通运输发展，必须坚持系统观念，加快建设综合立体交通网，全面提升网络效率和服务品质，推进交通运输绿色循环低碳转型，创新发展智慧交通数字交通，全方位提升全球资源配置能力，以促进共同富裕为使命建设人民满意交通。

China's economic and social development has entered a new stage of development, and the transportation has changed from the high-speed development to the high-quality development. From the perspective of the development orientation, the functions, the main contradicting problems, the development priorities, the supply capacity, the service level, the technical conditions, the institutional system and other related issues, the productivity level of the transportation industry has made a systematic breakthrough and stepped into a phased leap from a large transportation country to a powerful transportation country. In the new era, the sustainable development of the transportation presents new macro characteristics, which are reflected in the following aspects: strong supply and demand fundamentals of the transportation with comparative advantage of scaling the highland of scientific and technological innovation; a wide scale distribution, the structural complexity and the hierarchical diversity of the demand for passenger and freight transportation; a high demand for resources, funds and other elements; and an increased uncertainty of transportation pattern changes under the new development pattern. Under the basic national conditions, the structural problems of transportation will exist for a long time. To promote the sustainable development of transportation at a new starting point, we must adhere to the system concept, accelerate the construction of a comprehensive three-dimensional transportation network, comprehensively improve the network efficiency and service quality, promote the green, circular and lowcarbon transformation of transportation, innovate and develop intelligent transportation and digital transportation, promote the open development of transportation in an all-round way, and build a transportation that is satisfactory to the people with the mission of promoting common prosperity.
