哈长城市群核心-外围结构及发展阶段判断研究

以哈长城市群为例,从“核心-边缘”理论视角出发,将哈长城市群空间结构划分为核心区和外围区,然后运用模糊综合评价法,分析评价哈长城市群发育程度,判断哈长城市群发展阶段水平,并探讨哈长城市群成长策略。研究结果表明：哈长城市群空间结构具有“3核心-外围区”空间结构特征,发展阶段处在雏形发育的末期阶段。哈长城市群需要加强中心城市建设,促进人口与经济要素集聚,加强区域经济合作和区域基础设施建设,促进城市群的一体化发展。

The Core-Periphery Structure and the Growth Stage of Harbin-Changchun Urban Agglomeration

The growth of urban agglomeration has periodical characteristics and regular pattern, and it develops unevenly in spatial structure at beginning stage, which manifests a core-periphery structure. Harbin-Changchun urban agglomeration is one of the key urban agglomerations that is listed in state-level urbanization planning, so it is of great significance to analyze its spatial structure and measure its growth stage for the practical works. From the perspective of the core-periphery theory, this article divides Harbin-Changchun urban agglomeration into the core area and the peripheral area, then the article uses fuzzy comprehension evaluation method to set up the evaluation index system and the evaluation index standard to evaluate the growth degree and stage of Harbin-Changchun urban agglomeration. Finally, the article discusses the strategic policies for constructing Harbin-Changchun urban agglomeration. The result of the research indicates that the growth of Harbin-Changchun urban agglomeration has the characteristic of 3-core-periphery spatial structure. The core area includes 22 districts and the peripheral area includes 83 districts and counties. Harbin-Changchun urban agglomeration is in the later stage of its embryonic growth stage and urban system is immature. The core area is mainly agglomeration while radiation effect is not strong. The industrial structure in the peripheral area is characterized by convergence, the inter-city accessibility and informatization level are low, the infrastructure is not developed enough, and the development of the export-oriented economy is not sufficient. Regional development in the urban agglomeration is uneven. It is necessary for the core area of Harbin-Changchun urban agglomeration to continue to strengthen Harbin and Changchun as regional central cities and enhance the construction of the central cities. It is also necessary for the peripheral area to be deeply involved in their core area’s economy, improve connectivity with central cities, strengthen regional cooperation, and promote coordinated regional development.
