@article{oai:chuo-u.repo.nii.ac.jp:00012940, author = {中島, 美香}, journal = {国際情報学研究}, month = {Mar}, note = {application/pdf, On 18 July 2018, European Commission issued a violation decision in respect of Google’s Android based on abuses of market dominant position as provided by Article 102 of the Treaty on the Functioning of the European Union. European Commission has accordingly imposed fines amounting to €4,34 billion. In this article, based on the full text of the decision in this case, I would like to focus on the following three points and summarize the arguments. First, what is the Google’s Android business model? Second, what are the contents of the three Agreements that Google required device manufacturers, etc. to sign the Anti-Fragmentation Agreements, the Mobile Application Distribution Agreements and Portfolio-based revenue share agreements? Third, why did European Commission distinguish between the market for licensable operating systems(mainly Google’s Android OS)and the market for vertically integrated operating systems(mainly Apple’s iOS)as two separate markets in finding market definition or market dominance? And what impact did the indirect network effects as recognized in the Microsoft cases have in the deliberation of this decision?}, pages = {79--104}, title = {グーグルのアンドロイドとEU : 競争法上の問題欧州委員会の2018年違反決定書の概要について}, volume = {1}, year = {2021}, yomi = {ナカシマ, ミカ} }
