大都市中心区生产性服务业集群的空间溢出——以广州市天河区为例

空间溢出对产业集群形成发展具有重要意义。但空间溢出对生产性服务业集群的影响机制并不清楚。本文基于1 km×1 km网格和2013年广州市中心区——天河区的企业经济普查数据,采用空间数据分析技术,识别生产性服务业集群,分析集群特征,探测集群溢出类型。结果发现:(1)生产性服务业集群区位指向大城市中心区的核心地域,具有五种集群类型分异,空间呈不完全耦合。(2)生产性服务业集群空间规模受Jocobs型和MAR型两种溢出调控,在MAR型溢出作用下的集群空间规模相对较小。(3)信息服务业集群的溢出为负效应说明溢出作为一种潜在利益,在转化为集群优势的过程中存在过滤效应。

ANALYSIS OF THE SPILLOVER EFFECT OF PRODUCTIVE SERVICES CLUSTER IN CENTRAL METROPOLITAN AREA: TAKING TIANHE DISTRICT OF GUANGZHOU AS AN EXAMPLE

The spatial spillover is the combination of the knowledge spillover, the market spillover and other forms of spillover in a geographical space. It is of great significance to the formation and development of the industrial cluster. Nevertheless, the mechanism of its effects on the industrial cluster is still not very clear. Therefore, it is necessary and applicative to analysis the industrial cluster of the productive services at the central metropolitan area from the perspective of spatial spillover. In this paper, a grid of 1km×1km-fishnet created in the software of ArcMap is applied to identify the location of 28,134 firms of the productive services in the study area of Tianhe district, central Guangzhou city of China. Industrial cluster are detected, the characteristics of the cluster are analyzed and the spatial spillover effects are explored using spatial data analysis method and spatial regression model. Hot spot analysis and spatial outlier analysis are deployed on the whole productive services and it's 6 sub-sectors, which are the information services, the modern commercial and trade, the financial services, the professional services, the technological services and the cultural and creative industry. The result shows that industrial cluster of the productive services tend to emerge at the central area of the big city, with 5 types been detected. It's also found that cluster of the 6 sub-sectors of the productive services diverse in spatial pattern, their spatial distribution and forms appear imperfect match with each other as a result from the specialization at the same time the diversification respectively.
