中國市場監管部門周五表示，它已經對中國最大的在線學術數據庫——中國知網（CNKI）展開了反壟斷調查。

The State Administration for Market Regulation published the announcement on its website. It did not provide further details.

國家市場監管總局在其網站上發布了該公告，沒有提供進一步的細節。

CNKI, whose parent company is Tsinghua Tongfang, a Chinese state-owned software company linked to China’s elite Tsinghua University, said in a statement on WeChat it would cooperate fully with the probe and it would take it as an opportunity to carry out a self-examination.

中國知網的母公司是清華同方，一家與中國頂級大學清華大學有關的中國國有軟件公司，它在微信上發表聲明稱將全面配合調查，并將以此為契機進行自我檢查。

CNKI came under scrutiny last month after local media reported China’s top research group, the Chinese Academy of Sciences, said it would suspend its use of CNKI, citing high subscription fees.

上個月，當地媒體報道中國頂級研究機構——中國科學院表示將暫停使用中國知網，理由是訂閱費用過高，之后中國知網受到了審查。

The South China Morning Post reported that over the past decade at least six Chinese universities had suspended the use of CNKI over its fee increases.

《南華早報》報道稱，在過去十年中，至少有六所中國大學因中國知網收費上漲而暫停使用。

CNKI said on its website that at the end of 2017 it had the world’s largest readership, with more than 20 million individual users and an average daily retrieval volume of over 10 million.

中國知網在其網站上表示，截至2017年底，其擁有全球最大的讀者群，個人用戶超過2000萬，日均檢索量超過1000萬。

Asked about the controversy over CNKI fees, Tsinghua Tongfang told investors on Monday that both it and CNKI were aware of “public opinion” and that CNKI was looking to improve and make rectifications to its business model.

在被問及有關中國知網收費的爭議時，清華同方周一告訴投資者，它和中國知網都意識到了 “公眾意見”，中國知網正在尋求改善，并對其商業模式進行整改。
