Abstract
Collaboration is one of the important elements of the sixth industrialization. In this paper, cases of the sixth industrialization of the fishing sector are examined to clarify economic principles embedded in the partnerships. A literature review on economic and business theories is conducted to derive economic principles that are associated to functionality in business partnerships. Six theoretical patterns of collaboration are derived from a matrix of characteristics and contents of collaboration. The case studies of six successful cases of the sixth industrialization of the fishing sector that correspond to each pattern show that the collaboration bring about benefits to participated individual economic agents and further provide a secondary benefit as a system. It is concluded that it is not a single economic principle that produces such positive effects of collaboration, but the economics of collaboration is produced by a combination of diverse economic principles in a complex manner.
