PLOS One Flags Reference Problems in Agricultural Entrepreneurship Study
PLOS One has issued an Expression of Concern for a paper on promoting agricultural entrepreneurship through practical education in Chinese universities after editors identified problems with multiple references used to support the article’s claims. The notice does not retract the paper, but it does place readers on alert: several cited studies do not appear to back the statements they were attached to, and several additional references were introduced without editorial approval.
The concerns are concrete rather than procedural in the abstract. References 21, 30, 35, 36, and 39 do not appear to support the corresponding statements in the article. References 29, 54, and 56 were added without editorial approval and appear irrelevant to both the manuscript and the claims they were meant to support. In scholarly publishing, citation accuracy is not a cosmetic issue. It is the chain of evidence that tells readers whether a claim rests on a relevant prior study, a reasonable synthesis, or merely an assertion dressed up with bibliography.
The article at the center of the notice, authored by Hou, Song, Yang, Luo, Ding, Cao, and colleagues, was published in 2026 in PLOS One and examined agricultural entrepreneurship in the context of practical education in Chinese universities. The editorial notice does not restate the study’s findings or assess the validity of its conclusions. Instead, it focuses on the integrity of the citation record, which is enough to warrant caution when interpreting the paper.
A citation problem of this kind can weaken more than a single paragraph. When references are mismatched to the text, they can distort how evidence is framed, inflate the perceived support for a claim, or obscure the gap between what the literature actually shows and what an author wants to argue. In applied education research, where policy recommendations can travel quickly into university curricula and institutional planning, even one unsupported statement can propagate far beyond the original article.
The notice also points to editorial controls. References inserted without approval raise a separate issue from simple miscitation. They suggest the final reference list may not accurately reflect the version cleared through editorial review, which complicates post-publication trust in the record. Readers and indexers rely on the assumption that the published article represents a vetted and stable text; when that assumption fails, scrutiny shifts from the study’s claims to the reliability of the manuscript itself.
Why Unsupported Citations Matter in Applied Education Research
In research on entrepreneurship education, claims often move across multiple levels at once: individual skill-building, university programming, institutional policy, and regional economic development. A poorly supported citation can make a narrow observation look like a settled consensus. It can also create the appearance that a particular intervention has a stronger evidence base than it actually does.
That matters because practical education models are often justified by linking classroom activity to workforce readiness, venture creation, and rural development. If the bibliography does not truly support those links, the paper’s argumentative structure becomes unstable. Readers may still find the topic important, but they cannot assume the supporting literature has been represented faithfully.
One sentence can change the weight of an entire section. If a reference is irrelevant, the claim may still sound polished while losing its evidentiary anchor.
The editors’ response reflects a familiar principle of publication ethics: when the supporting record is compromised, transparency takes priority over silence. An Expression of Concern signals uncertainty rather than final judgment. It tells readers that the article remains part of the literature, but not without a warning label attached to its citation framework.
What the Editorial Notice Does and Does Not Mean
An expression of concern is not a retraction, and this distinction matters for readers who track the scientific record. The published article remains online, but PLOS One is explicitly advising caution. The notice does not establish misconduct, nor does it claim the article’s main conclusions are false. It does, however, establish that the editorial team identified enough citation irregularities to question the reliability of key portions of the manuscript.
For authors, this kind of notice can have consequences beyond reputation. Citation integrity is part of the methods of scholarly communication, not an afterthought. When references are used improperly, the issue can affect peer review, editorial oversight, and the downstream use of the article in reviews, policy documents, and teaching materials.
For readers, the practical response is straightforward: treat the paper as provisional when using it to justify educational or policy claims. The safest reading is to separate the topic from the trustworthiness of the supporting apparatus. Agricultural entrepreneurship in university settings may remain a legitimate subject of inquiry, but the citation problems mean this particular article should not be used uncritically as evidence.
The date attached to the editorial notice is October 15, 2026, and the linked article citation identifies the paper in PLOS One 21(2): e0340670. The editors’ warning leaves the manuscript in circulation while making clear that its reference base does not currently inspire confidence. For a paper whose purpose is to connect practical education with entrepreneurship outcomes, the missing link is not the subject matter itself. It is the reliability of the evidence trail the article claims to build on.
