# Zuoyebang(作業帮) ## 会社概要 Baidu元幹部のHuo Jianbinが2015年に設立した中国のオンライン教育スタートアップ。Baiduからのスピンオフ企業。 直近では2020年12月のシリーズEラウンドでAlibaba、Tiger Global、ソフトバンクビジョンファンド、Sequioa Capital China、FountainVestPartnersなどから16億ドルを調達している。 ## 事業概要 ### 対象年齢 幼稚園生から12年生(日本だと高校3年生)、中国ではK-12と呼ばれる年齢を対象に、ライブストリーミング授業、オンライン宿題添削など、遠隔学習サービス/プラットフォームを提供している。 ### ユーザー数 総AU数は4億人、MAUは1億7000万人+となっており、うち5000万人が毎日サービスを利用しているとのこと。MAUが1億を超えるEdTechサービスは中国で唯一。K-12の総ボリュームは約2億人であるため相当数がZuoyebangを利用していると考えられる。 ### アプリ機能 ライブストリーミング授業のような一般的なオンライン教育アプリのほかに、写真検索が可能なQ&Aや、古文読解のアシスト、作文検索など多数の学習ツールが備わっている。 オンラインクラスの機能もあり、教師と1対1で対話できるほか、写真や音声メモを教師と共有したり、試験を受けてその答え合わせをしたり、全国の同年齢の生徒とコミュニケーションを取ったりすることができる(N高っぽい)。 ![enter image description here](https://snipboard.io/4bQX8O.jpg) ## 市場環境 https://equalocean.com/analysis/2020072014303 ### 政府における教育財政支出の増加 2019年現在、中央政府の教育財政支出は年々増加しており、GDPに占める財政教育支出の割合は7年連続で4%を超えている。 ### 家計における教育支出の増加 近年の国内経済の急速な発展に伴い、人々の生活水準は徐々に向上し、家計の貯蓄も増加している。 そのなかでK12を含む世帯では、家計支出の20.6%が教育支出となっており、また、52.3%の世帯が子供を学外のビジネス教育に参加させている。 ### K12市場全体の伸長 政府と家計の教育への支出増加に伴って、オンライン教育市場とK12市場が共に伸長している。 - 2018年 - K12の市場規模は4,000億元 - オンラインのK12市場規模は302億元 - 2019年 - 中国のオンライン教育市場の規模は3,200億元 - うち21.3%がK12教育=K12オンライン教育市場の規模は680億元 - → 2倍成長 - iiMediaは、中国のオンライン教育市場の成長率について今後3年間で19〜24%となる予想を提示 ### 地域格差の是正 都市部では試験の成績を向上させるためのツールとして個別指導に注目が集まっているが、田舎の世帯ではアクセスが難しい状況が続いている。この状況下において教育資源が比較的貧しい地域に住む学生のあいだで、オンライン家庭教師やオンライン教材などが広く普及するようになっている。
