(1)両技術問の補完性が強い時, 技術開発を行う企業は決して技術AあるいはBだけを開発することはない. 一方, この補完性が弱い時, 技術AあるいはBのみが開発される可能性が生じ, 補完性が弱くなればなるほど, 更なる技術の開発を企図しない傾向が強くなる. (2)補完性が強い時, 開発費用が低水準でなければ, クロスライセンス契約は結ばれないが, 補完性が弱い時, 開発費用の水準が中程度であっても, クロスランセンス契約が結ばれる. しかも, 補完性が弱く場合なればなるほど, 開発費用がより高水準であってもクロスライセンス契約が結ばれる傾向が高まる.","subitem_description_type":"Abstract"},{"subitem_description":"Our paper aims at investigating technology choice without cross-licensing and possibility of cross-licensing agreement by constructing the duopolistic model where complementary cost-reducing technologies (technologies A and B) can be developed. Our model is regarded as an amalgam of Mills and Smith (1996)'s model and González-Maestre (2008)'s one. Our main results are as follows: (1) If the degree of complementarities between two technologies is strong, then both firms do not develop technologies A or B solely; otherwise, then they may do so. Note that in the case where the degree is quite weak and the level of development cost is medium, they develop one of two technologies solely. (2) An increase in the degree of complementarities tends to deteriorate the cross-licensing agreement. Especially, two firms disagree cross-licensing when the degree is strong and development cost is not low.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"27229","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Ohkawa, Takao"}]},{"nameIdentifiers":[{"nameIdentifier":"27230","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Shinkai, Tetsuya"}]},{"nameIdentifiers":[{"nameIdentifier":"27231","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Okamura, Makoto"}]}]},"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"},{"subitem_text_value":"広島大学大学院社会科学研究科"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"大川, 隆夫"}],"nameIdentifiers":[{"nameIdentifier":"27226","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"新海, 哲哉"}],"nameIdentifiers":[{"nameIdentifier":"27227","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"岡村, 誠"}],"nameIdentifiers":[{"nameIdentifier":"27228","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":"shk061002006.pdf","filesize":[{"value":"904.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"shk061002006.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/17052/files/shk061002006.pdf"},"version_id":"129cd016-0c5c-4282-a504-818e7726221a"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"補完的技術","subitem_subject_scheme":"Other"},{"subitem_subject":"技術選択","subitem_subject_scheme":"Other"},{"subitem_subject":"費用削減技術","subitem_subject_scheme":"Other"},{"subitem_subject":"クロスライセンス","subitem_subject_scheme":"Other"},{"subitem_subject":"クールノー複占","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":"補完的技術における技術選択とクロスライセンス契約(<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":"補完的技術における技術選択とクロスライセンス契約(<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":"17052","relation_version_is_last":true,"title":["補完的技術における技術選択とクロスライセンス契約(<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":"2022-12-19T03:55:54.329986+00:00"}
