摘　　要：在总结和借鉴国内外就业中心界定和识别方法的基础上,针对特定群体之特性,优补了特定群体的就业中心的界定,修正了现有识别方法,并进一步进行了效果检验。首先,在中心界定上,依照“整体之一部分”原则,参照特定群体与城市整体在人口构成和影响能力的差异,在现有就业中心定义的基础上对特定群体的就业中心进行了细化分类。其次,在识别流程上,从细化类型和降低门槛两方面考虑,在原有就业中心识别过程中增加了必要环节、增补了适当方法。最后,在识别效果上,以南京主城区外来务工人员就业中心识别为例,对比了修正前后方法的识别结果。结果显示,一方面,修正后的方法可以更细化、精准的识别出特定群体的就业中心,能更加突出特定群体与城市总体的宏观关联,有助于更深入地挖掘特定群体的就业空间结构特征;另一方面,结合跨时间的动态对比研究,修正后的方法还可为特定群体就业中心的变动特征和动力机制挖掘提供技术型基础。Based on the definition of employment center and related identification methods in China and foreign countries,in view of the characteristics of specific population groups,this paper redefines the concept of employment center of specific groups,modifies the existing identification methods,and checks the validity.Firstly,in terms of redefining the employment center,following the principle of“part of a whole”,this paper takes into consideration the differences in population composition and influence between the specific groups and the overall urban population,and subdivides the employment centers of specific groups on the basis of the existing definition.Secondly,in terms of the identification process,the original identification methods for employment centers are modified to work with specific groups from two perspectives:subdivision and lower threshold.Thirdly,in terms of verification,the paper takes the employment centers of migrant workers in the main city of Nanjing as an example and compares the results of identification methods before and after modification.The results show that,on the one hand,the modified method can be more detailed and accurate in identifying the employment centers of specific groups and highlighting the macro correlation between specific groups and the overall urban population,which is helpful in further exploring the structural characteristics of employment space of specific groups;on the other hand,in combination with the dynamic comparative study,the modified method can provide a technical basis for exploring the changing characteristics and driving mechanism of employment centers for specific groups.
