In contrast to recent studies showing that R&D investment results in a large cost differential between firms, thereby leading to firm agglomeration, we find that licensing activities following R&D investment always lead to the maximum differentiation between firms and the mitigation of price competition. We also show that licensing activities induce the socially optimal effort level of R&D activity.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"27220","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Matsushima, Noriaki"}]},{"nameIdentifiers":[{"nameIdentifier":"27221","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Matsumura, Toshihiro"}]}]},"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":"大阪大学社会経済研究所"},{"subitem_text_value":"東京大学社会科学研究所"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"松島, 法明"}],"nameIdentifiers":[{"nameIdentifier":"27218","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"松村, 敏弘"}],"nameIdentifiers":[{"nameIdentifier":"27219","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":"shk061002004.pdf","filesize":[{"value":"570.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"shk061002004.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/17050/files/shk061002004.pdf"},"version_id":"9e3f5385-1d01-4ee8-87c7-4c809859b35d"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"立地モデル","subitem_subject_scheme":"Other"},{"subitem_subject":"ライセンス契約","subitem_subject_scheme":"Other"},{"subitem_subject":"研究開発投資","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":"ライセンス契約と製品差別化戦略(<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":"ライセンス契約と製品差別化戦略(<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":"17050","relation_version_is_last":true,"title":["ライセンス契約と製品差別化戦略(<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":"2022-12-19T03:55:54.495632+00:00"}
