As the dominant industry in the post-industrial society , the agglomeration of service industry has become a new hot spot in the research fields of economic geography , industrial economics and urban economics . At present , research mainly focuses on four aspects : comparison with manufacturing agglomeration;space distribution of agglomeration , including overall space design and distribution;causes of agglomeration , such as the collective study process , social factors , co-agglomeration and so on , and effect of agglomeration . These studies have provided a frame of reference for the coordinated development of the secondary and tertiary sectors through adjustment of space structure and development of service industry agglomeration . On the other hand , there is an urgent need to study issues like how to construct an analytical framework for service industry agglomeration based on new economic geography theory , how to measure the degree of agglomeration , and how to advance the interactive development of service agglomeration and regional economies .
