乡镇生产性服务业空间集聚特征研究——以江苏省常熟市为例

The Spatial Characteristics of Producer Service Agglomeration in Town The Case of Changshu in Jiangsu Province

以常熟市各乡镇为研究区域,以2007-2011年生产性服务业就业人数为基础数据,运用主成分分析、空间基尼系数、区位商等方法和指标对常熟市各乡镇生产性服务业集聚的整体水平、行业特征及专门化率进行研究。结果表明：常熟市服务业集聚整体差异显著,空间上整体呈现出一种典型的单中心、大梯度等级化集聚发展态势;相对于苏州,常熟市的生产性服务业相对集聚程度不高且趋势不够明显;乡镇之间的生产性服务业内部行业的结构差异均较大,专业化分工比较明显;常熟市整体生产性服务业在苏州市的专业化优势不够明显,地位不够突出;行业中除交通运输、仓储和邮政业以及房地产业的专门化率较高外,其他4个行业的专门化率均很低。

Taking towns of Changshu as the case region,mainly based on Generalized Principal Component Analysis,Spatial Gini-coefficient,Krugeman specialization index and other methods and indicators,this article measured the model of locality distribution,the industrial characteristics,the specialized rate of producer service industry in each town of this region from 2007 to 2011.The results indicate that the general spatial distribution shows itself to be the situation of a typical single center,large gradient-level development trend.Compared with Suzhou,the degree of agglomeration of producer service in Changshu was not very high and its agglomeration trend was not obvious.There are big structure differences among internal sectors in producer service industry and the division of labor based on specialization in each town is distinct.Compared with Suzhou,the whole producer service of Changshu didn＇t have obvious specialization advantages.Among all the producer service industry,the specialization rate of all producer service industry were low except for transportation,warehousing and postal service,as well as the real estate industry.
