甘肃省区域空间格局形成机制与发展战略

Formation mechanism and development strategy of regional spatial pattern of Gansu Province

区域空间格局及其形成机制对制定空间发展战略具有理论意义。以甘肃省为例,根据2000、2010年和2020年甘肃省统计资料,运用引力模型和断裂点模型识别区域空间格局,基于地理探测器分析形成机制,进而提出空间发展战略。结果表明:甘肃省空间格局分别为河西走廊一体化发展区、陇中同城化发展区和陇东南协同发展区三大分区。区域空间格局形成的演化机制因地理尺度的差异而不同,2000—2020年人口发展和经济水平对区域空间格局的形成一直发挥着基础性作用,政策调控则发挥着关键性作用,因子间的共同交互作用推动甘肃省空间格局的形成。从三大分区层面提出河西走廊一体化发展区形成“一轴、四圈”、陇中同城化发展区形成“一核牵引、五极并进”、陇东南协同发展区形成“四极”平行发展的新发展空间思路;省域层面提出“手指形”高质量空间发展战略,促使甘肃省由增长极模式和点-轴模式的发展阶段转向区域网络极核模式。

Analysis of the formation of regional spatial patterns has theoretical significance for the formulation of high-quality spatial development strategies.Regional spatial patterns map the economic development relations between regions that affect the level and efficiency of regional economic development.Regional spatial pattern research can greatly enrich the theory of coordinated development in the new era.Taking the Gansu Province of China as an example,this study uses gravity and breaking point models to identify the province’s regional spatial pattern,geographic detectors to analyze the pattern’s formation mechanism and proposes a high-quality spatial development strategy.The results showed that:the spatial pattern of Gansu Province is identified as comprising three sub-regions:an integrated development zone in Hexi Corridor,an urban development zone in central Gansu Province,and a coordinated development zone in southeast Gansu Province.The factors influencing the formation of regional spatial patterns and the related evolutionary mechanisms vary across different geographical scales.Population and economic factors have always played a fundamental role in the formation of regional spatial patterns,while policy factors also play a key role.The interaction of these factors promotes the formation of Gansu’s spatial pattern.The study proposes that the integrated development zone in Hexi Corridor should form one axis and four circles,the urban development zone in central Gansu Province should form one-core traction and five poles that advance in parallel,and the coordinated development zone in southeastern Gansu Province should form a four-pole parallel development.At the provincial level,a“finger-shaped”high-quality spatial development strategy has been proposed,which has prompted Gansu Province to shift from the development stage of the growth pole model and the point-axis model to the regional network-pole core model.The study provides a theoretical reference for the construction of a one-core,three-zone development pattern for Gansu Province,and it thus contributes to achieving high-quality provincial development and laying the foundation for the fulfillment of common prosperity.
