兰州市生产性服务业空间集聚特征研究

Study on Spatial Agglomeration Characteristics of Producer Services in Lanzhou City

生产性服务业是我国近年来经济发展的主要方向,其集聚能促进三次产业加速融合、协同发展,对城市等级体系重构和城市内部空间塑造具有重要影响。基于兰州市三次经济普查数据,运用区位商、空间基尼系数、赫芬达尔指数、EG指数等方法,对兰州市生产性服务业空间集聚特征进行了研究。结果表明:兰州市生产性服务业具有集聚特性,但仍处于集聚的初级阶段,空间上呈单中心集聚结构;区域集聚程度与行业间集聚程度存在差异,各研究单元发展程度层次不齐;区位因素、集聚效益、政策导向和工业发展需求是影响兰州市生产性服务业空间分布的原因。

Producer services was the main direction of economic development in China in recent years,the concentration of producer services could promote the integration of three industries,coordinated development. It had an important influence on the reconstruction of urban hierarchy system and the shaping of urban interior space. Based on the three economic census data of Lanzhou,this paper used the methods of location quotient,spatial Gini coefficient,Herffendal index and EG index. The characteristics of spatial agglomeration of producer services in Lanzhou were studied. The results showed that the producer services in Lanzhou had the characteristics of agglomeration,but they were still in the primary stage of agglomeration,with a single-center agglomeration structure in space. There was a difference between regional agglomeration degree and inter-industry agglomeration degree. The spatial distribution of producer services in Lanzhou was influenced by location factor,agglomeration benefit,policy orientation and industrial development demand.
