根据2001、2005、2009、2013年广东省21个地级市服务业发展数据,基于改进的空间引力模型,构建服务业外向功能量、城市流强度、服务业空间联系量、接受辐射水平、服务业发展潜力等指标,综合考察广东省市级服务业集聚水平、服务业质量、空间联系与空间结构的时空演化过程。通过比对发现,广东省市级服务业发展潜力、城市流强度与空间联系强弱在空间上存在显著的耦合关系,且空间联系的紧密程度对地区服务业空间结构的时空演化有显著推动作用,随着空间联系的逐步增强,广东省服务业空间结构的复杂程度也在逐步提高,由期初的“行政—特区”双核结构逐步演化为“多核”并最终过渡到复杂的网络结构。研究发现,服务业集聚水平、服务业空间联系与城镇化水平在区域分布上实现完美的空间拟合,都主要集中分布于珠三角城市区域。这表明服务业集聚水平与服务业空间联系程度是城镇化发展的重要驱动因素,服务业集聚程度的提高以及服务业空间联系的加深有助于加速推动区域间人口、信息、资本等资源要素的流通,主导并推动地区城镇化进程向前发展。
Based on the data of service development of 21 prefecture-level cities in Guangdong in 2001, 2005, 2009 and 2013 and based on the improved model of space gravity, this paper constructs the service export-oriented function, urban flow intensity, service space connection, radiation level acceptance, Industry potential and other indicators, a comprehensive study of Guangdong Province-level service industry agglomeration level, service quality, spatial relations and spatial structure of the temporal evolution. Through the comparison, it is found that there is a significant coupling relationship between the development potentiality of city-level service industry in Guangdong Province and the strength of urban flow and the strength of spatial connection in space, and the closeness of spatial connection has a significant role in promoting the spatial and temporal evolution of the spatial structure of service industry in Guangdong. With the gradual increase in spatial relations, the complexity of the service space structure in Guangdong Province is gradually increasing. From the beginning of this period, the dual-core structure of administration-special district gradually evolved into a multi-core system and finally the transition to a complex network structure. The study found that the level of service industry agglomeration, service space and urbanization in the region to achieve a perfect spatial distribution fitting, are mainly concentrated in the Pearl River Delta urban area. This shows that the level of service agglomeration and service space connection is an important driving factor for the development of urbanization. The increase of agglomeration of service industry and the deepening of the spatial connection of service industry help to speed up the promotion of resource elements such as population, information and capital among regions Circulation, dominance and promote the progress of urbanization in the region.
