Plagiarism Policy

Plagiarism Policy

Conditions for submission: plagiarism, self-plagiarism, duplicate submission, and preprint disclosure.

Sinergi International Journal of Economics upholds high standards of academic integrity and only considers original and unpublished scholarly work. All submitted manuscripts are screened using Turnitin to assess textual similarity. However, the similarity score is only a screening tool; the final determination of plagiarism, improper quotation, duplicate publication, or self-plagiarism remains a matter of editorial judgment.

Plagiarism includes the use of another person's words, ideas, economic theories, models, datasets, statistical results, econometric outputs, tables, figures, policy analyses, indicators, or findings without proper acknowledgment. Self-plagiarism or text recycling refers to the substantial reuse of one's own previously published material without proper citation, disclosure, or scholarly justification. Both are considered serious violations of publication ethics.

Authors are responsible for ensuring that all quotations, paraphrases, borrowed concepts, economic frameworks, datasets, equations, econometric models, statistical outputs, figures, tables, and reproduced materials are clearly cited and properly referenced. Where necessary, authors must also obtain permission for reused copyrighted or proprietary material.

A low similarity score does not automatically mean the manuscript is free from plagiarism, and a high similarity score does not automatically prove misconduct. Editors assess the source, context, nature, location, extent, attribution, and scholarly significance of the matching material before making a decision.

Duplicate or redundant publication occurs when an author submits or publishes substantially the same work in more than one venue without proper disclosure, cross-referencing, or scholarly justification. This includes substantial overlap in title, objectives, theoretical framework, datasets, variables, sample, econometric specification, statistical analysis, findings, discussion, policy implications, or conclusions.

Manuscripts that are under review in another journal, already formally published, or submitted simultaneously to more than one outlet will not be considered. If any part of the manuscript has appeared previously in another form, including conference proceedings, working papers, discussion papers, institutional reports, theses, dissertations, policy reports, technical reports, book chapters, or another language version, authors must disclose this clearly at the time of submission.

The journal may consider manuscripts previously posted as preprints, provided that the preprint has not undergone formal journal publication and that the preprint status is fully disclosed during submission.

Authors must provide the preprint server name and URL or DOI, and must ensure that the preprint version does not conflict with copyright, data-use agreements, confidential economic information, institutional restrictions, ethical obligations, contractual conditions, or third-party rights. Once the article is published in the journal, authors are encouraged to update the preprint record with a link to the final published version.

Editorial Follow-Up and Author Responsibilities

• All manuscripts may be checked through Turnitin before peer review and, where necessary, after revision.
• The Editorial Board may provide or request a similarity report during the editorial process.
• Authors must revise problematic sections carefully, especially where quotation, paraphrasing, citation, theoretical attribution, source acknowledgment, data attribution, or reuse of economic analysis is insufficient.
• Authors should not attempt to reduce similarity mechanically by replacing isolated words while retaining substantially copied sentence structures, economic arguments, methodological descriptions, analytical narratives, or interpretations.
• Established economic theories, econometric methods, statistical procedures, policy frameworks, indices, classifications, and standard indicators must still be appropriately cited where derived from prior literature or institutional sources.
• Previously published tables, graphs, equations, conceptual models, policy diagrams, statistical figures, or datasets must be clearly identified and used only with appropriate attribution and permission where required.
• Failure to address similarity concerns adequately may result in rejection or discontinuation of the review process.
• If plagiarism is identified after publication, the journal will take appropriate action according to its ethics, correction, and retraction policies.
