Cost-reducing innovation uses two types of technologies; the firm specific technology and the complementary technology. We examine the efficiency of firms'choices of technology types when firms cooperate with respect to the complementary technology. The main findings are as follows. In the industry with the higher (lower) technological complementarity, firms overinvestment (underinvest) in the firm specific technology and underinvestment (overrinvest) in the complementary technology. In the industry with the higher technological complementarity, firms tend to gain more profits when the degree of product differentiation is high. The opposite may occur when the degree of product differentiation is low.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"27234","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kinokuni, Hiroshi"}]},{"nameIdentifiers":[{"nameIdentifier":"27235","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Shinkai, Tetsuya"}]}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学社会科学研究所"}]},"item_4_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00108966","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03873307","subitem_source_identifier_type":"ISSN"}]},"item_4_subject_15":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"300","subitem_subject_scheme":"NDC"}]},"item_4_text_21":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_text_value":"Institute of Social Science, The University of Tokyo"}]},"item_4_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"立命館大学経済学部"},{"subitem_text_value":"関西学院大学経済学部"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"紀國, 洋"}],"nameIdentifiers":[{"nameIdentifier":"27232","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"新海, 哲哉"}],"nameIdentifiers":[{"nameIdentifier":"27233","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-06-08"}],"displaytype":"detail","filename":"shk061002007.pdf","filesize":[{"value":"936.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"shk061002007.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/17053/files/shk061002007.pdf"},"version_id":"ce3f1925-33b7-4b5c-8470-d9128347c1b8"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"研究開発","subitem_subject_scheme":"Other"},{"subitem_subject":"補完的技術","subitem_subject_scheme":"Other"},{"subitem_subject":"企業特殊的技術","subitem_subject_scheme":"Other"},{"subitem_subject":"製品差別化","subitem_subject_scheme":"Other"},{"subitem_subject":"クロスライセンス","subitem_subject_scheme":"Other"}]},"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":"製品差別化複占市場における技術選択と技術補完性(<特集>研究開発戦略・特許制度と産業組織)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"製品差別化複占市場における技術選択と技術補完性(<特集>研究開発戦略・特許制度と産業組織)"}]},"item_type_id":"4","owner":"1","path":["918","919"],"pubdate":{"attribute_name":"公開日","attribute_value":"2011-06-01"},"publish_date":"2011-06-01","publish_status":"0","recid":"17053","relation_version_is_last":true,"title":["製品差別化複占市場における技術選択と技術補完性(<特集>研究開発戦略・特許制度と産業組織)"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T03:55:54.194533+00:00"}
