摘　　要：在核心–边缘理论的框架下,基于“极化”与“扩散”的研究视角,以蚌埠为例,对其从省域核心城市到边缘城市的变迁进程、阶段特征及内在机制进行系统研究。研究结果显示:①交通、工业、创新3个维度核心地位的建立是蚌埠“核心”崛起的动力来源与表征,遵循了“核心”形成的理论路径;②城市的边缘化主要表现为战略、交通地位下降以及工业、创新维度的“核心”竞争力下滑;③“核心”的边缘化以及“边缘”锁定的动因源于政策的倾斜与市场经济自发的不均衡性,其中政策力量起主导作用;同时边缘化与城市收缩的不断累积形成负向反馈,削弱了“核心”的扩散效应;④创新提出“核心”逆向演替的本土化理论解释,即政策力量成为核心–边缘结构的主导机制,能够强化“核心”的极化作用并引导“核心”发挥扩散效应,但市场机制对于扩散效应的具体实施结果具有决定性作用。The traditional core-periphery theory mainly focuses on how the edge develops to the core.However,the core can also develop inversely to the edge in practice.This research takes Bengbu as an example to study systematically the process and internal mechanism from provincial core city to the marginal city under the theory of core-periphery theory basing on the research aspect of"polarization"and"diffusion".The result shows that:1)The external characteristics of the rise of the"core"of Bengbu is manifested in the transportation hub location where the Jinpu Railway and the Huaihe River water transport meet,and the internal characteristics are manifested in the economic status of the core city of industrial development in Anhui Province and the innovation resource agglomeration advantages of the core city of the Hewubeng National Independent Innovation Demonstration Zone.At the same time,the above three dimensions are also the power force for the rise of the"core"of Bengbu,following the theoretical path of the formation of the"core"under the framework of the traditional core-periphery theory.2)The external characteristics of Bengbu's"marginalization"are mainly manifested in the marginal location of strategic virtual areas such as the regional integration of the Yangtze River Delta,the Hefei metropolitan area,and the Anhui River urban belt,as well as the superposition effect of the decline of the status of railway transportation hubs and the spatial scarcity of land and water transportation hubs.And the internal characteristics are mainly manifested in the insufficient momentum of economic development in the industrial dimension,as well as the resulting outflow of resources and factors,and the lack of innovation power.3)The marginalization of''core''and the motivation of''marginalization''locking is originated from the inclination of policies and the spontaneous imbalance of the market economy.Among them,policy force plays a leading role,through the subjective initiative choice of core cities,and changes the path of re
