PLOS ONE Flags Citation Problems in Study on Agricultural Entrepreneurship Education in China

Editors at PLOS ONE have issued an Expression of Concern for a 2026 study that examined how practical education in Chinese universities promotes agricultural entrepreneurship among students. The notice, published on October 15, 2026, does not retract the paper but formally warns readers that multiple problems with its cited literature mean the findings should be interpreted with caution. The flagged study, authored by Hou and colleagues, appeared in the journal earlier that year and explored a topic of growing interest to educators and policymakers: whether hands-on, entrepreneurship-oriented teaching can steer graduates toward careers in modern agriculture.

The concerns center on the article’s reference list. According to the editorial notice, five of the works cited in the paper—References 21, 30, 35, 36, and 39—do not appear to support the statements for which they were cited. In scholarly publishing, citations function as the evidentiary scaffolding of an argument; when a source is cited to substantiate a claim it does not actually address, the chain of evidence linking data to conclusion is weakened, even if the underlying data themselves remain sound.

A second, arguably more serious issue involves three additional references. The editors report that References 29, 54, and 56 were introduced without editorial approval and appear to be irrelevant both to the article as a whole and to the specific statements they were attached to. References are normally finalized during peer review, and any post-review insertion of new sources is supposed to be reviewed and approved by the handling editor. Sources that appear in a published paper without that approval, and that bear no evident relationship to the text, raise questions about how the manuscript evolved between acceptance and publication.

Citing the cumulative nature of these issues, the PLOS ONE editors chose an Expression of Concern rather than an immediate retraction. This notice type occupies a middle ground in the taxonomy of scholarly corrections. A retraction signals that a paper’s conclusions are unreliable or that its conduct was sufficiently serious to invalidate the work. An Expression of Concern, by contrast, alerts the research community that unresolved questions exist—questions that may later be resolved through further investigation, author responses, or institutional review. Readers are advised to interpret the article with caution while the record remains in this provisional state.

The underlying study investigated a question with real policy weight in China. Agricultural entrepreneurship has been promoted as a pathway for engaging university graduates in rural revitalization, food security, and the modernization of farming. Practical education—laboratory work, field placements, business plan competitions, and university-run farms—is often cited in the education literature as the mechanism that converts classroom theory into entrepreneurial intent. The Hou paper joined a substantial body of work arguing that such programs can measurably increase students’ willingness to start agricultural ventures.

That relevance is precisely why the citation problems matter. Studies of education interventions influence curriculum design, funding decisions, and subsequent research agendas. If the literature a study builds on includes sources that do not support the claims attributed to them, or sources added without oversight, then the interpretive framework surrounding the study’s own data becomes unreliable. Other researchers citing the paper may inherit those weakened foundations, propagating unsupported statements through the scholarly record—a phenomenon researchers have described as citation distortion.

The notice also illustrates how journals detect such problems after publication. Post-publication scrutiny increasingly relies on readers, automated reference-screening tools, and volunteer sleuths who compare cited claims against the actual content of the cited papers. Reference-integrity checks—verifying that each citation supports its attached statement—have become a standard part of editorial triage. When several independent failures cluster in a single manuscript, editors often treat the pattern as grounds for a notice, since the issues are unlikely to be isolated typographical errors.

For the authors, an Expression of Concern is not the end of the process. Journals typically invite a response, and the notice may be updated, replaced by a retraction, or lifted if the concerns are satisfactorily resolved. The original paper remains accessible and citable, but the notice is linked to it permanently in indexing databases, ensuring that anyone who encounters the study also encounters the warning. The PLOS ONE editors stated only that readers should interpret the article with caution; they did not allege misconduct or specify what further action may follow.

The episode arrives amid broader ferment over research integrity in the agricultural and education sciences, fields where policy-relevant findings attract intense scrutiny. Expression of Concern notices have become more common as journals confront volume-driven peer review and the difficulty of verifying every citation before publication. For readers tracking how practical education shapes entrepreneurial outcomes in Chinese universities, the editors’ message is clear: the study’s claims now require independent verification before they can be treated as established evidence.
