With the development of science and technology, the deep integration of products and technologies has made modularity in the field of industrial products has achieved good results, from IBM-360 computer to Volkswagen's MQB platform can be seen, in various industrial fields, the research and practice of modular production network has become one of the focuses of industrial upgrading. Based on the current research needs, the existing modularization literature is reviewed from three aspects: industrial modularization, industrial cluster modularization and modular production network.
