Thus, we performed attribution analysis on the spot prices in the Japanese wholesale electricity market by a linear multiple regression model with economical and physical parameters in electricity trades as predictor variables. The analysis shows that the standardized partial regression coefficients as the incidence degree to the spot prices are statistically significant. Furthermore, the week variation, the deepest snowfall and the CIF fuel price are determined as the variation factors of the spot prices at the rate of incidence degree of 40%, 30%and 20%, respectively. It is concluded that the analysis using the proposed model provides the major variation factors and their incidence degree to the spot prices.","subitem_description_type":"Other"}]},"item_10002_publisher_30":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"秋田大学工学資源学部"}]},"item_10002_source_id_27":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13457241","subitem_source_identifier_type":"ISSN"}]},"item_10002_source_id_35":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AA11410906","subitem_source_identifier_type":"NCID"}]},"item_10002_version_type_37":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"中嶋, 明宏"}],"nameIdentifiers":[{"nameIdentifier":"2544","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"佐藤, 正志"}],"nameIdentifiers":[{"nameIdentifier":"2545","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"吉村, 昇"}],"nameIdentifiers":[{"nameIdentifier":"2546","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nakajima, Akihiro","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"2547","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sato, Masashi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"2548","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yoshimura, Noobru","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"2549","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":"2017-02-16"}],"displaytype":"detail","filename":"koushi28a.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"koushi28a.pdf","url":"https://air.repo.nii.ac.jp/record/722/files/koushi28a.pdf"},"version_id":"1c12e3ff-f44b-4b0c-9907-2886a4772a59"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"卸電力","subitem_subject_scheme":"Other"},{"subitem_subject":"取引市場","subitem_subject_scheme":"Other"},{"subitem_subject":"スポット価格","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":"日本卸電力取引市場におけるスポット価格の要因分析","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"日本卸電力取引市場におけるスポット価格の要因分析"}]},"item_type_id":"10002","owner":"3","path":["641"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-01-29"},"publish_date":"2008-01-29","publish_status":"0","recid":"722","relation_version_is_last":true,"title":["日本卸電力取引市場におけるスポット価格の要因分析"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-07-25T11:17:33.249310+00:00"}
