Specifically, it compares the profit structures of rice farming on paddy farms with organic, environmentally friendly, and conventional rice farming methods to test working hypotheses based on previous research. Inverse-probability-of-treatment weighting combined with generalized boosted models was applied to estimate the propensity score weights of a sample of paddy farms collected from the Farm Management Survey. Results showed that organic farms have a higher unit value of rice compared with conventional farms; however, they also incur higher expenditures. Conversely, environmentally friendly farms have a high unit value of rice; however, their expenditures are not higher. Nevertheless, the results indicated that the profit structures, particularly in organic farms, differ across farm scales and locations.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10001_identifier_registration":{"attribute_name":"identifier_registration","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.34444/0002000103","subitem_identifier_reg_type":"JaLC"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"農林水産省 農林水産政策研究所","subitem_publisher_language":"ja"}]},"item_10001_source_id_11":{"attribute_name":"item_10001_source_id_11","attribute_value_mlt":[{"subitem_source_identifier":"AA11614280","subitem_source_identifier_type":"NCID"}]},"item_10001_source_id_9":{"attribute_name":"item_10001_source_id_9","attribute_value_mlt":[{"subitem_source_identifier":"1346-700X","subitem_source_identifier_type":"PISSN"}]},"item_10001_version_type_20":{"attribute_name":"出版タイプ","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":"日田, アトム","creatorNameLang":"ja"},{"creatorName":"ニッタ, アトム","creatorNameLang":"ja-Kana"},{"creatorName":"NITTA, Atomu","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"177","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"70967629","nameIdentifierScheme":"e-Rad_Researcher","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=70967629"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2025-03-24"}],"displaytype":"detail","filename":"250324_sk2501_01.pdf","filesize":[{"value":"611 KB"}],"format":"application/pdf","license_note":"Copyright © 農林水産省 農林水産政策研究所\nPolicy Research Institute, Ministry of Agriculture, Forestry and Fisheries, Japan","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"250324_sk2501_01.pdf","url":"https://primaff.repo.nii.ac.jp/record/2000103/files/250324_sk2501_01.pdf"},"version_id":"afcacb51-e643-4c6d-bd7d-d1bd84ceac84"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"稲作","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"有機栽培","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"特別栽培","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"収益構造","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"rice farming","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"organic farming","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"environmentally friendly farming","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"profit structure","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"item_resource_type","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"稲作における有機栽培及び特別栽培の収益構造 ―『営農類型別経営統計（個別経営）』個票を用いて―","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"稲作における有機栽培及び特別栽培の収益構造 ―『営農類型別経営統計（個別経営）』個票を用いて―","subitem_title_language":"ja"},{"subitem_title":"Profit Structures of Organic and Environmentally Friendly Rice Farming Methods in Japan: Evidence from Farm-Level Data","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"4","path":["1742858856721"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2025-03-24"},"publish_date":"2025-03-24","publish_status":"0","recid":"2000103","relation_version_is_last":true,"title":["稲作における有機栽培及び特別栽培の収益構造 ―『営農類型別経営統計（個別経営）』個票を用いて―"],"weko_creator_id":"4","weko_shared_id":-1},"updated":"2025-03-25T04:35:02.760088+00:00"}
