| Outline of Final Research Achievements |
This study investigated technology fusion-type patents from the viewpoint of the network structure of citation or co-occurrence of classifications. Accessory parts manufacturers have technology fusion networks where (1) there are many fusion relationships in proportion to the number of technology elements; (2) while some technology elements have fusion relationships with a variety of other elements, most technology elements have few fusion relationships; (3) while some elements are applied both as core technologies and as auxiliary technologies related to them, most elements are applied only either as core or auxiliary technologies in technology fusion-type research and development; (4) each technology element does not tend to be combined with a variety of other elements; and (5) a technology element does not tend to be repeatedly combined with the same element in research and development.
