In the years following reunification, the polycentric German urban system has undergone changes as regards the location of employees in knowledge-intensive business service (KIBS) professions. For the purposes of analysing functional spatial patterns, those spatial patterns exhibiting above-average increases or decreases in the numbers of employees within KIBS professions were identified on the basis of employment data. Correlations in the spatial affinities within service professions of differing compositions were mapped, leading to the identification of four patterns. Based on these patterns, spatial differentiation arising between the various services in the German urban system has been interpreted as functional specialisation. The basis of functional specialisation, with reference to the concept of knowledge bases, is differentiation into the following three service industries: technological services, consulting services and creative services.

KIBS 工人在德国哪里工作？大都市、区域性和工业化腹地 KIBS 就业模式的转变

在重新统一后的几年里，多中心的德国城市体系在知识密集型商业服务 (KIBS) 职业的雇员位置方面发生了变化。为了分析功能空间模式，在就业数据的基础上确定了 KIBS 专业内员工人数出现高于平均水平的增长或减少的空间模式。绘制了不同组成的服务行业内空间亲和力的相关性，从而确定了四种模式。基于这些模式，德国城市系统中各种服务之间产生的空间差异被解释为功能专业化。功能专业化的基础，参考知识库的概念，
