Under this situation, it is necessary for electric power companies to improve their management efficiency in order to survive in a competitive market. This study examines management efficiency of vertically integrated electric companies, which consist of several divisions, such as generation, transmission, distribution and so forth. Previous studies mainly focused on efficiency of only a specific division independently. However, we should evaluate firm-level management efficiency based on divisional efficiencies, because these divisions are closely linked each other. For measuring firm-level efficiency, we apply a network DEA model that considers a streamlined relationship among divisions under vertical integration. Furthermore we newly proposed a constrained network DEA model to obtain more practical efficiency index.","subitem_description_type":"Abstract"}]},"item_12_description_8":{"attribute_name":"分野","attribute_value_mlt":[{"subitem_description":"総合政策 / Multi Disciplinary policy studies","subitem_description_type":"Other"}]},"item_12_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"6126","nameIdentifierScheme":"WEKO"}],"names":[{"name":"筒井, 美樹","nameLang":"ja"}]},{"nameIdentifiers":[{"nameIdentifier":"6127","nameIdentifierScheme":"WEKO"}],"names":[{"name":"刀根, 薫","nameLang":"ja"}]}]},"item_12_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24545/00000973","subitem_identifier_reg_type":"JaLC"}]},"item_12_publisher_12":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"GRIPS Policy Research Center ","subitem_publisher_language":"en"}]},"item_12_relation_16":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://ideas.repec.org/p/ngi/dpaper/07-03.html"}],"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://ideas.repec.org/p/ngi/dpaper/07-03.html","subitem_relation_type_select":"URI"}}]},"item_12_text_10":{"attribute_name":"発行年","attribute_value_mlt":[{"subitem_text_value":"2007-07"}]},"item_12_text_5":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"電力中央研究所 / Central Research Institute of Electric Power Industry"},{"subitem_text_value":"政策研究大学院大学 / National Graduate Institute for Policy Studies"}]},"item_12_version_type_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_1693541285410":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicIssueDates":{"bibliographicIssueDate":"2007-07-01","bibliographicIssueDateType":"Issued"},"bibliographicVolumeNumber":"DP07-03","bibliographic_titles":[{"bibliographic_title":"GRIPS Discussion Papers","bibliographic_titleLang":"en"}]}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"TSUTSUI, Miki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"TONE, Kaoru","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","filename":"DP07-03.pdf","filesize":[{"value":"155.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"DP07-03.pdf","url":"https://grips.repo.nii.ac.jp/record/973/files/DP07-03.pdf"},"version_id":"1591d729-2901-48b5-b9ae-2f4ca447a520"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Network DEA","subitem_subject_scheme":"Other"},{"subitem_subject":"electric utilities","subitem_subject_scheme":"Other"},{"subitem_subject":"vertical integration","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"technical report"}]},"item_title":"Application of Network DEA Model to Vertically Integrated Electric Utilities","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Application of Network DEA Model to Vertically Integrated Electric Utilities","subitem_title_language":"en"}]},"item_type_id":"12","owner":"16","path":["16"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2007-07-01"},"publish_date":"2007-07-01","publish_status":"0","recid":"973","relation_version_is_last":true,"title":["Application of Network DEA Model to Vertically Integrated Electric Utilities"],"weko_creator_id":"16","weko_shared_id":-1},"updated":"2023-11-20T08:56:46.444680+00:00"}
