Technological diversification is that the technology of the firm spans over more than one technology. In recent years, technological diversification has been widely known as another side of diversification strategy of the firm.\n　Previous study about business diversification strategy indicates that the Japanese firms have performed business restructuring after the second half of the 1990s. This fact highlights the necessity of empirical study about the technological diversification of them. 　In order to examine this subject, this study takes up the process of long-term changes of technological diversification in Japanese electronics firms using the patent data from 1987 to 2006. As a result of statistical analysis, it is shown that the overall quantitative expansion of technological development activities have progressed steadily in Japanese electronics firms. On the other hand,　these firms have focused their technological portfolio after the\nsecond half of the 1990s.　These empirical results provide the fact that reexamination of\ntechnological portfolio was performed in many firms when business reorganization was progressed in Japanese firms around 2000.","subitem_description_type":"Abstract"}]},"item_2_description_7":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"滋賀大学経済学部研究年報, 第19巻, pp. 105-115","subitem_description_type":"Other"}]},"item_2_full_name_2":{"attribute_name":"著者(ヨミ)","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{"name":"タケナカ, アツオ"}]}]},"item_2_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{"name":"Takenaka, Atsuo"}]}]},"item_2_publisher_35":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"滋賀大学経済学部"}]},"item_2_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN1047649X","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1341-1608","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"竹中, 厚雄"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-09-13"}],"displaytype":"detail","filename":"06研究年報Vol.19-竹中.pdf","filesize":[{"value":"771.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"06研究年報Vol.19-竹中.pdf","url":"https://shiga-u.repo.nii.ac.jp/record/8878/files/06研究年報Vol.19-竹中.pdf"},"version_id":"238fc816-16d3-4947-bd71-191ed0c895d8"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"日本企業における技術の多角化のプロセス","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"日本企業における技術の多角化のプロセス"}]},"item_type_id":"2","owner":"1","path":["943"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-12-17"},"publish_date":"2012-12-17","publish_status":"0","recid":"8878","relation_version_is_last":true,"title":["日本企業における技術の多角化のプロセス"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T20:02:25.326115+00:00"}
