| 摘 要： | 中国城市群从区域向空间网络的转变,成为城乡统筹发展功能的主体地域单元。基于“交通—产业”的耦合视角,以京津冀城市群为研究区域,选取北京、天津、石家庄、唐山作为城市群发育的辐射中心,结合空间网络分析、引力模型、多层次空间结构MSS-Tree算法,测度识别京津冀城市群空间结构及现状发育范围。结果发现：①京津冀城市群还不成熟,辐射中心周边的辐射发育区“岛、洞”现象明显,表现为连片分布的大城市阴影区;其中北京市周边缺乏成熟副中心,天津市受到北京极化作用影响,辐射区大幅萎缩;石家庄、唐山辐射区发育不足,需首先加强自身经济建设;②交通、产业辐射发育范围重合度较低,交通的先导作用加速了中小城镇生产要素流失,形成环京津贫困带。据此提出了自下而上整合、由内向外扩展的地区发展策略建议。 |

| Abstract: | The interaction of production factors among cities plays a significant role in the spatial expansion of urban agglomerations. Meanwhile, it drives the change of urban agglomerations from a single-level flat regional space into a multi-level network system. The shift of Chinese urban agglomerations from segregated regions to spatial networks has become the focus of academic research in recent years. Studies have advanced an argument that the relations of traffic and industry between each city-pair not only provide internal dynamics for the spatial expansion and hierarchical organization of urban agglomeration, but also describe the development state of urban agglomeration. Based on the perspective of coupling relationship between traffic and industry, this study identified the multi-level spatial structure and development scope of the Beijing-Tianjin-Hebei urban agglomeration by spatial network analysis, gravity model, and Multi-level Spatial Structure Tree (MSS-Tree), using socioeconomic data, traffic volume data, and enterprise network data. We first selected the municipal districts of Beijing, Tianjin, Shijiazhuang, and Tangshan cities as four radiation centers based on the result of comprehensive strength calculated by factor analysis. Then we combined the gravity model with the MSS-Tree algorithm, and the result shows that continuity, hierarchy, and difference coexist in the theoretical spatial structure of the urban agglomeration. Meanwhile, we applied traffic volume data and enterprise network data to the MSS-Tree algorithm, and the result shows that current spatial structure presents the characteristics of fragmentation, hollow, and jumping, which is quite different from the theoretical structure. According to the comparison between the current scope and the theoretical scope, the current development scope is smaller, and there is obvious an "island and cave" phenomenon in the radiation area of radiation centers, which show contiguous distribution of metropolitan shadow areas. For the four radiation centers, there is a lack of mature sub-centers around Beijing; the spatial scale of radiation area around Tianjin is shrinking greatly because of the polarization effect of Beijing; and the radiation areas around Shijiazhuang and Tangshan are poorly developed, indicating that the two cities need to strengthen their own economic construction. Further, the comparison between traffic and industry radiation areas reveals the phenomenon that traffic develops first while industry lags behind. The unbalanced coupling relationship between traffic and industry leads to low coincidence degree in radiation areas of these two factors. The leading role of traffic accelerates loss of production factors from small or medium-sized cities, thus forms the poverty belt around Beijing and Tianjin. From the perspective of traffic-industry coupling relationship, this study explored the existing problems and their mechanism, which is significant for efficient synergy in the spatial development of urban agglomerations. Finally. Based on the perspective of local government, this article proposed regional development strategies of integration from bottom to top and expansion from inside to outside. |
