我国省域副中心城市的理论与实践均兴起于湖北,而后逐步推向全国。在回溯省域副中心城市提出的理论与实践背景、推广过程,分析其发展动因、功能特点与政策支持机制的基础上,提出发展壮大省域副中心城市的政策建议,即抓住机遇,优化省域副中心城市布局,加大政策支持力度,赋予其更大的经济社会管理权限,完善基础设施和服务功能,构建现代化产业体系,以副中心为龙头建设城市群、都市圈,增强其辐射能力,推进省域治理体系和治理能力现代化。

The theory and practice of sub-provincial central cities originated in Hubei Province and subsequently spread nationwide. Based on a review of the theoretical and practical backgrounds and the promotion process of provincial sub-central cities, as well as an analysis of their development motivations, functional characteristics, and policy support mechanisms, this paper proposes policy recommendations for the development and expansion of provincial sub-central cities. Specifically, it suggests seizing opportunities, optimizing the layout of provincial sub-central cities, increasing policy support, granting them greater economic and social management powers, improving infrastructure and service functions, building a modern industrial system, and leveraging sub-central cities as the leaders to construct urban agglomerations and metropolitan areas, thereby enhancing their radiation capabilities and promoting the modernization of provincial governance systems and governance capacities.
