中文摘要：

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。
