分類是研究的第一步，服務業的管理必須基於有意義的分類，才可能提出
規範性的結論。此外，服務業的無形產出，必須透過細緻的服務傳送系統
設計來傳遞給顧客。因此服務業的研究首要工作，在從抽象的層次中提出
對服務業無形特性的有效分類。經由文獻檢討及實務觀察，本文提出三項
服務業的產出分類構面：經濟性、社會性及心理性利益，稱之為服務核心
。以此三構面將台北市的服飾零售業分為四種類型：經濟心理性、心理性
、混雜性及經濟性零售店。除了對每一類零售店績效較佳者相互間比較、
以凸顯類型的差異外，並針對每一類型零售店內的各樣本，以迴歸及類神
經網路求得影響績效最重要的服務傳送系統項目，最後並提出相關的建議

Classification is the first step for research.
Normative suggestions cannot be provided unless meaningful
classification is available in service management. Meanwhile,
intangible output in service organizations usually is
transferred to customers through delicate service delivery
system. Therefore the primary task in service management
research is to devise efficacious, theoretical
classifications to govern inherent intangibility in service
management. Through literature review and field study, this
paper proposed three classifying dimensions for fashion
retailing, which were termed service cores consisting
of economic, social, and psychological benefits. Based on
these three dimensions, four types of retailing firms were
derived with clustering analysis. Between groups, better
performers were extracted to compare with each other, which
demonstrated the significance of differences between these
four retailing types. Within groups, multiple regression and
neural network analyses were employed to determine important
factors in service delivery system. Relevant suggestions and
discussions were given to conclude the findings.
