Understanding the Regional Integration Process from the Perspective of Agglomeration and Urban Networks: Case Study in Central China

Abstract

Previously, urban planning approaches have tended to convert local agglomeration into network connections to advance urban development. However, is this successful experience learned from developed counties appropriate for developing countries? Scholars hold different opinions on this debate. To answer this question, we need to examine the effects of urban agglomeration in developing countries with a quantitative method. In this paper, we introduced a method of examining network connections from a geospatial perspective to explore the practice and spatial consequences of regional integration using a new concept of “coupling distance” based on metal valence bond theory. Then we applied this method to conduct an empirical case study of the urban agglomeration in the middle reaches of the Yangtze River region in China. We found that: (1) the real integration scale of the investigated urban areas was less than one-fourth the planned area, as most of interactions between cities are local, although we see the positive facilitation of urban networks on cross-provincial integration. (2) In terms of spatial consequences, the study area demonstrated phenomena of “agglomeration shadows”, “enclaves” and “inverse integration”. Specifically, these “agglomeration shadows” were all in their province’s geometric centers, which seemed to have suffered a “central position curse”. (3) Both “enclaves” and “inverse integration” call for a readjustment of government-led regional integration planning. Differently, the former has a positive attitude towards integration while the latter holds the opposite attitude. This study hopes to provide operationalizing methods and guidelines for planners and decision makers in the field of regional integration planning.

Spatial structure and influencing factors of regional city supply networks in manufacturing: A case study of Shandong, China

“…Network connections among cities are the development trend in urban areas (Wang et al, 2022). With the improvement of information and communication technology and transportation infrastructure, the rigid "major city-hinterland" spatial hierarchy dominated by the central place theory is gradually dissipating.…”

The Identification and Dynamics of Urban Shadow Areas from the Perspective of People Flows—A Case Study of Nanjing

“…Some studies have emphasized the policy constraints on the development of shadow areas from core cities [22,29] and the functional division of labor between the shadow area as well as its immediately adjacent core city or core area [7]. Meanwhile, other studies put industrial structures [29], the characteristics of people's daily activities [6], regional integration strategies [15], and network externalities [32,33] as the key points.…”

Regional Integration from within: Transition to the Greater Nairobi Metropolitan Region in Kenya from the Perspective of Metal Valence Bond Theory

“…Hence as far as the Greater Nairobi Metropolitan Region is concerned, the metal valence bond theory provides a strong similitude for investigating interactions in the four-city system (Nairobi, Machakos, Kajiado, and Kiambu), both externally and internally. The level of exchange shows the intensity of interaction due to different dynamic and interactive relationships through the element (city/town) allocation formed by the towns in the metropolitan region (Wang, Zhang, Zang, & Duan, 2022). These four towns would meaningfully combine to form a formidable matching model that is influenced by their various demands or capabilities.…”
