Abstract: The connotation of service modularization contains three levels: service system, service organization and service industry. The results of the relative studies are all focused around the four main lines of service system modularization, services product modularization, service industry modularization and service organization modularization. There are more qualitative empirical and conceptual researches，but less quantitative researches. Therefore，to analyze service modularization from the multidimensional perspective of both macro and micro industrial organization with both the qualitative and quantitative research methods will be the general direction of future researches.

Key words: industrial organization；service modularization；research perspective；research review
