This finding suggests that the SMD system's alleged district-level effect on producing two-candidate competition is weaker if subnational-level politicians, who have strategic interactions with national-level politicians, are elected under a more proportional electoral system. Our findings suggest that the degree of subnational-level partisan fragmentation determines the degree of bipartism in a national legislature.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"107647","nameIdentifierScheme":"WEKO"}],"names":[{"name":"HORIUCHI, Yusaku"}]},{"nameIdentifiers":[{"nameIdentifier":"107648","nameIdentifierScheme":"WEKO"}],"names":[{"name":"NATORI, Ryota"}]}]},"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_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":"オーストラリア国立大学クローフォード経済政治研究大学院"},{"subitem_text_value":"関西大学総合情報学部"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"堀内, 勇作"}],"nameIdentifiers":[{"nameIdentifier":"107645","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"名取, 良太"}],"nameIdentifiers":[{"nameIdentifier":"107646","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":"2017-06-26"}],"displaytype":"detail","filename":"KJ00005386538.pdf","filesize":[{"value":"1.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00005386538.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/17147/files/KJ00005386538.pdf"},"version_id":"5a564a44-c8b2-4c5c-93ca-27efb9684a2a"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"選挙制度改革","subitem_subject_scheme":"Other"},{"subitem_subject":"並立制","subitem_subject_scheme":"Other"},{"subitem_subject":"都道府県議会議員選挙","subitem_subject_scheme":"Other"},{"subitem_subject":"M+1の法則","subitem_subject_scheme":"Other"},{"subitem_subject":"空間競争モデル","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":"二大政党制の実現を阻害する地方レベルの選挙制度(<特集>選挙制度改革後の政党政治)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"二大政党制の実現を阻害する地方レベルの選挙制度(<特集>選挙制度改革後の政党政治)"}]},"item_type_id":"4","owner":"1","path":["943","945"],"pubdate":{"attribute_name":"公開日","attribute_value":"2009-11-06"},"publish_date":"2009-11-06","publish_status":"0","recid":"17147","relation_version_is_last":true,"title":["二大政党制の実現を阻害する地方レベルの選挙制度(<特集>選挙制度改革後の政党政治)"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T03:55:58.642190+00:00"}
