Under the market structureconduct-performance (SCP) paradigm, the Herfindahl index suggests that the degree of competition in the JNLI industry has decreased remarkably since 2001. However, assumptions about the market performance of the JNLI industry (degree of competition and cost efficiency) based on the SCP paradigm have incited criticism, as this model presumes market performance from market structure, and in most cases, direct estimation of market performance is not performed. Therefore, this paper aims to directly estimate market performance using the Lerner index and cost efficiency. The results of the present analysis suggest that the IBL revision and the JFBB stimulated the first stage of competition in the JNLI industry."},{"subitem_description":"本論文では、産業組織論的観点から損害保険産業の競争度及び費用効率性を推定し、保険業法および金融ビッグバン以降の規制緩和の影響を評価した。ハーフィンダール指数を見ると，市場構造・行動・成果仮説のもとでは、損害保険産業の競争度は2001 年から著しく低下していることが示唆された。しかし、市場構造・行動・成果仮説には、直接的に市場成果を捉えるのではなく、市場構造から間接的に市場成果を捉えているに過ぎないという批判があることから、損害保険産業の市場成果(競争度および費用効率性) を直接的に推定し、保険業法および金融ビッグバン以降の規制緩和の影響を評価しようと試みた。分析の結果、保険業法改正・金融ビッグバンはその後の状態から判断すると初期段階の競争状態を作り出した可能性が高いことが明らかとなった。"}]},"item_6_description_40":{"attribute_name":"資源タイプ(DSpace)","attribute_value_mlt":[{"subitem_description":"Working Paper","subitem_description_type":"Other"}]},"item_6_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15099/00002080","subitem_identifier_reg_type":"JaLC"}]},"item_6_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"FACULTY OF ECONOMICS UNIVERSITY OF TOYAMA"}]},"item_6_relation_41":{"attribute_name":"シリーズ","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"Working Paper / No.240"}]}]},"item_6_version_type_16":{"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":"姉崎, 正起子"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"本間, 哲志"}],"nameIdentifiers":[{},{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-02-15"}],"displaytype":"detail","filename":"240re3_Homma.pdf","filesize":[{"value":"1.5 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"240re3_Homma.pdf","url":"https://toyama.repo.nii.ac.jp/record/2086/files/240re3_Homma.pdf"},"version_id":"844e63a3-fb1c-4bca-99a8-b0da6cd27b5e"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"損害保険産業","subitem_subject_scheme":"Other"},{"subitem_subject":"ラーナー指数","subitem_subject_scheme":"Other"},{"subitem_subject":"費用効率性","subitem_subject_scheme":"Other"},{"subitem_subject":"保険業法","subitem_subject_scheme":"Other"},{"subitem_subject":"金融ビッグバン","subitem_subject_scheme":"Other"},{"subitem_subject":"Japanese Non-Life Insurance Industry","subitem_subject_scheme":"Other"},{"subitem_subject":"Lerner Index","subitem_subject_scheme":"Other"},{"subitem_subject":"Cost Efficiency","subitem_subject_scheme":"Other"},{"subitem_subject":"Insurance Business Law","subitem_subject_scheme":"Other"},{"subitem_subject":"Japanese Financial Big Bang","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":"technical report","resourceuri":"http://purl.org/coar/resource_type/c_18gh"}]},"item_title":"損害保険の産業組織に関する実証的研究 : 競争度及び費用効率性の推定と規制の評価","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"損害保険の産業組織に関する実証的研究 : 競争度及び費用効率性の推定と規制の評価"}]},"item_type_id":"6","owner":"3","path":["407"],"pubdate":{"attribute_name":"公開日","attribute_value":"2009-09-25"},"publish_date":"2009-09-25","publish_status":"0","recid":"2086","relation_version_is_last":true,"title":["損害保険の産業組織に関する実証的研究 : 競争度及び費用効率性の推定と規制の評価"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-07-25T13:56:18.035501+00:00"}
