Agglomeration Characteristics and Factors Influencing Business Office Space in Changsha
Abstract
Because business office space is the main functional space of the spatial structure of a city, it is important to explore its spatial layout characteristics to promote efficient use of urban space. Therefore, taking Changsha as an example, this study constructed an explanatory model of the agglomeration phenomenon and ultimately explored the influences of other spatial factors in the city on the agglomeration characteristics of business office space, from the perspective of spatial heterogeneity, based on the business office space POI(Point of Interest) in Changsha and by utilizing standard deviation ellipse analysis, the Getis-Ord Gi* index, and geographically weighted regression analysis. The study produced several interesting results: 1) The business office agglomeration in Changsha mainly has the spatial structure of "one main, one secondary, two belts, and multiple clusters." The central agglomeration has a high degree of overlap with the city's main traffic arteries, with a cross-shaped clustering along the two strips of Wuyi Avenue and Furong Middle Road, leading to the main positive value area in Furong Square. Although there is a tendency for business office space in Changsha to develop to the west of the Xiangjiang River, the strength of development is insufficient, and the main and secondary business districts still lie to the east of the Xiangjiang River. The concentration strength of business office space in the Liugoulong-Guanshaling area has not yet reached the level of the secondary business district. 2) The city is a large collection of multi-factor spaces, and the uneven distribution of various factors causes the influence on the agglomeration of business office space to vary from one region to another. Different influencing factors have either an attracting or inhibiting effect on the agglomeration of business office space. The average degrees of influence are shopping services>hotels>public transport>main roads>parks and green areas>external transport>metro>flats>scenic locations>residential areas. 3) Each influencing factor was characterized as a "center-periphery" influence mode. Influenced by the "business dividend," the clustering of business office space in the center is strongly influenced by the commercial space, metro, main roads, and park green spaces factors, and the coordinated development of these spaces in the core of the city can greatly contribute to enhancing the regional agglomeration economy and the formation of the urban CBD. With increasing distance from the center, the driving effect of the commercial dividend gradually decreases, leading to a decrease in the influence of the four factors and thus causing the business office space in the periphery to be influenced to form clusters mainly by residential space, public transport, and other factors. The study aimed to refine and analyze the factors influencing the location of the business office space layout to promote harmonious development of functional spaces within the city.
