In April 2004, with the advancement of competition, the Telecommunications Business Law was substantially amended to realize drastic institutional reforms, including the abolition of regulations on market entry, tariffs and agreements, in principle. The regulation system greatly shifted from ex ante to ex post basis. Consequently, the number of enterprises entering the telecommunications market has largely increased, and due to the advancement of technological innovations, the emergence of diverse services such as mobile communications and Internet access, the promotion of deregulatory measures and other factors, the competition among the telecommunications carriers progressed, prompting the significant development of the telecommunications market. Two kinds of drastic structural changes -- \"a shift to mobile\" and \"a shift to broadband and IP\" -- are occurring in the Japanese telecommunications market. In such a rapidly changing circumstances, it is essential to evaluate the market competition with a focus on fixed-telephony, mobile communications, and broadband services, in order to figure out the trend of the telecommunications markets accurately and rapidly. The MIC has conducted the Competition Review since fiscal year 2003 to ensure that the tendencies above are reflected in government policies. This article firstly considers about market definition from a legal viewpoint, and secondly, it generalizes the current condition of competitions in the telecommunications business by summarizing the Competition Review, and finally, the article examines the challenges that the Competition Review face in the telecommunications business field.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"27278","nameIdentifierScheme":"WEKO"}],"names":[{"name":"林, 秀弥"}]}]},"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_subject_15":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"300","subitem_subject_scheme":"NDC"}]},"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":"名古屋大学大学院法学研究科"},{"subitem_text_value":"名古屋大学高等研究院"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Hayashi, Shuya"}],"nameIdentifiers":[{"nameIdentifier":"27277","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":"2017-06-08"}],"displaytype":"detail","filename":"shk060003002.pdf","filesize":[{"value":"3.3 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"shk060003002.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/17074/files/shk060003002.pdf"},"version_id":"26aa0237-ad88-4045-a8c0-ec3c2985087a"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Competition Review","subitem_subject_scheme":"Other"},{"subitem_subject":"Telecommunications","subitem_subject_scheme":"Other"},{"subitem_subject":"Market Definition","subitem_subject_scheme":"Other"},{"subitem_subject":"Antimonopoly Law","subitem_subject_scheme":"Other"},{"subitem_subject":"SSNIP Test","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Competition Review in the Japanese Telecommunications Market (<Featured Theme>Economic Regulation and Industrial Organization in Public Utility with Network Facilities)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Competition Review in the Japanese Telecommunications Market (<Featured Theme>Economic Regulation and Industrial Organization in Public Utility with Network Facilities)"}]},"item_type_id":"4","owner":"1","path":["926","927"],"pubdate":{"attribute_name":"公開日","attribute_value":"2011-05-20"},"publish_date":"2011-05-20","publish_status":"0","recid":"17074","relation_version_is_last":true,"title":["Competition Review in the Japanese Telecommunications Market (<Featured Theme>Economic Regulation and Industrial Organization in Public Utility with Network Facilities)"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T03:55:54.805264+00:00"}
