Fake data, paper mills and plagiarism: Can China's retrospective paper audits clean up academic misconduct?

Chinese universities are reviewing previously published academic papers as part of wider efforts to strengthen research integrity and address misconduct, including data fabrication, image duplication, authorship irregularities and the commercial production of academic manuscripts.

The retrospective checks are intended to identify violations in research already published and hold researchers accountable for misconduct. The exercise also targets paper mills, which produce and sell academic manuscripts for researchers seeking publications.

Guangdong Polytechnic has directed researchers to examine papers formally published since Jan 1, 2017, under a recently issued university notice. They must verify publication records against databases such as the China National Knowledge Infrastructure (CNKI) and Web of Science.

The review covers retractions, corrections, fabricated data, duplicated images and the buying and selling of academic papers. Researchers must also check whether author order and institutional affiliations are accurate.

The university has asked researchers to sign academic integrity commitment letters and report any identified problems truthfully. The requirements apply to previously published work within the specified review period.

Anhui Jianzhu University and Anhui College of Traditional Chinese Medicine have also announced similar retrospective checks. Their reviews cover academic papers published since Jan 1, 2020.

At Anhui Jianzhu University, the priority areas include duplicated images, improper authorship and paper trading. Researchers must verify the accuracy of recorded data and ensure experimental procedures can be traced.

The university has also introduced requirements for reviewing manuscripts before submission and retaining research data. Studies involving human participants or animals must undergo the required ethical review.

Meanwhile, the notice issued by Anhui College of Traditional Chinese Medicine identifies eight categories of priority concerns. These include plagiarism, duplicate publication, falsification of image data and repeated use of images.

China strengthens research integrity rules at universities

The latest university-level reviews come as China continues to tighten its research integrity requirements. Universities are being asked to move beyond investigating individual misconduct cases and establish regular supervision, process management and mechanisms to prevent academic violations.

In 2024, China's Ministry of Education issued guidelines placing primary responsibility for research integrity on universities. The guidelines require institutions to establish dedicated bodies and coordinate integrity-related work across departments.

They also call for research integrity checks to become part of teacher recruitment, promotion and performance assessment. This approach aims to make academic accountability a regular part of university administration.

Universities have continued to disclose confirmed cases of academic misconduct publicly. Sun Yat-sen University and Nankai University, for instance, have issued notices concerning problems involving research images, data and authorship.

Researchers found responsible for violations have faced several disciplinary measures. These include removal from office, demotion, disqualification from promotion and project applications, and termination of employment.

Expert calls for long-term research integrity mechanism

Tang Daisheng, a professor at the School of Economics and Management at Beijing Jiaotong University, said retrospective reviews are intended to verify the authenticity of existing research and establish whether authors have made the contributions claimed in published papers.

He said the exercise could help improve the academic environment and support a shift away from excessive reliance on research papers in academic evaluations.

"Research integrity is a bottom line that should not expire," Tang said, emphasizing that retrospective inspections must work alongside presubmission reviews and research data retention requirements.

He added that combining these measures would create a closed-loop system for monitoring academic work and addressing misconduct.

Tang identified the lack of adequate postpublication scrutiny as a major gap in the existing academic oversight system. Published research is often incorrectly treated as work that no longer requires examination once it has passed the initial review and publication process.

He also referred to China's Law on Academic Degrees, which permits degrees to be withheld or revoked in cases involving ghostwriting, plagiarism or fabrication. According to Tang, the provision demonstrates that accountability for academic misconduct does not have a time limit.

Tang called for a sustainable research integrity mechanism built around four priorities.

The first is to strengthen institutional accountability by ensuring that different university departments share responsibility for academic integrity. The second involves incorporating research integrity into faculty management through integrity records and signed commitment letters.

His third recommendation is to improve manuscript screening before submission and ensure the preservation of original research data. The fourth is to reform academic evaluation systems and move away from the "papers only" approach.

"Only in this way can papers return to their original purpose of seeking truth," he said.

Chinese graduate students respond to retrospective paper reviews

The university-level inspections have also raised concerns among postgraduate students, particularly those preparing academic dissertations and research papers.

A second-year journalism graduate student at Sun Yat-sen University, identified by the surname Zhang, said she feels pressure because of the ongoing reviews. She is particularly concerned about self-reviews of degree theses.

Zhang noted that she had come across cases in which master's degrees were revoked, adding to her concerns about the consequences of academic integrity violations.

She said she intends to follow her university's requirements concerning restrictions on AI-generated content and the retention of original research materials. However, she finds maintaining these materials after graduation cumbersome.

Zhang said the retrospective reviews could act as a deterrent against academic misconduct. She also pointed to the increasing ability of artificial intelligence tools to leave identifiable traces in generated content.

As a result, passing off AI-generated academic papers as original research is becoming more difficult, particularly in important academic settings where authenticity and originality are closely examined.
