CAS Halts Funding for 30 High-Cost OA Journals | Nature Communications, Science Advances Affected | Research Publication Policy Shift

The Groundbreaking Announcement from CAS

The Chinese Academy of Sciences (CAS), China's premier research institution overseeing more than 100 institutes and employing over 50,000 researchers, has made headlines with a bold policy shift in research publication funding. Effective March 1, 2026, CAS will prohibit the use of central fiscal funds—including those from the Ministry of Science and Technology (MOST), National Natural Science Foundation of China (NSFC), and CAS projects—to reimburse Article Processing Charges (APCs) for papers published in over 30 high-cost open access (OA) journals. This move targets journals charging at least $5,000 per article, far above the global average of around $2,000, signaling a strategic pivot to curb escalating publication costs and bolster domestic alternatives.

This decision, circulated via an internal "2026 Annual Warning Journal Notice," has sparked widespread discussion on platforms like Xiaohongshu and Zhihu, where researchers debate its implications for careers and global publishing dynamics. While CAS has not yet publicly released the full list, prominent titles confirmed include Nature Communications, Science Advances, Cell Reports, Advanced Science, and Results in Physics.

Spotlight on Affected Journals: The High-APC Hit List

Among the over 30 journals flagged for excessive fees, several high-impact venues stand out. Nature Communications, a staple in multidisciplinary science, recently hiked its APC to $7,350 for 2026 (from $6,990), equivalent to roughly 52,000 RMB—making it a prime target. Science Advances follows at $5,450, Cell Reports at $5,790, with Advanced Science and Results in Physics also implicated due to their steep charges and heavy reliance on Chinese submissions.

Notably, lower-cost OA giants like PLOS One and Scientific Reports escape the cut, as their APCs fall below the $5,000 threshold. This selective targeting underscores CAS's focus on fiscal prudence rather than outright rejection of OA models.

The Rising Tide of APCs: A Cost Breakdown

APCs, or Article Processing Charges, are fees authors pay publishers to make their work immediately open access upon acceptance. While OA democratizes access, the model has ballooned costs for high-profile journals. In 2025 alone, Chinese authors contributed about 40% of papers to Nature Communications and Science Advances, with 10% bearing CAS affiliations—translating to millions in reimbursements.

China's overall scientific publishing spend exceeds $1 billion annually, with 90% flowing to international publishers via APCs and subscriptions. For context, a single Nature Communications paper costs more than many domestic grants cover for publication, straining budgets amid rising demands. This policy caps reimbursement, forcing self-funding or hybrid paywalled options (free for authors in journals like Nature).

CAS Journal Partition Table: The Evaluation Backbone

CAS's Journal Partition Table (分区表), updated yearly, ranks ~12,000 journals into four zones based on discipline-normalized impact factors, citations, and international collaboration. Top 5% are 1区 Top, crucial for evaluations, grants, and promotions in Chinese universities.

The Early Warning List complements this by flagging risks: previously misconduct/paper mills (120 journals this year), now high-APC OA. This dual system guides funding and career decisions across China's academia, influencing universities from Tsinghua to Fudan.

For researchers at Chinese colleges, publishing in 1区 journals remains key for tenure and funding—check tips on crafting a strong academic CV amid these changes.

Strategic Reasons: Cost Control and National Ambition

• Fiscal Efficiency: Redirect funds from foreign publishers to domestic priorities.
• Boost Homegrown Journals: China's "Excellence Action Plan" targets 400 world-class journals by 2025, with 178 English OA titles (half APC-free).
• Accountability: Aligns with Xi Jinping's emphasis on responsible public spending.

Immediate Impacts on China's Research Ecosystem

Chinese universities, reliant on CAS/NSFC grants, face tough choices. Graduate students, often footing bills personally, may shun these venues, slowing careers. Institutions like Peking University report heavy OA reliance; expect submission drops of 10-40%.

• Risk to evaluations: Fewer 1区 pubs hurt promotions.
• Shift to hybrids/domestic: Boost for Protein & Cell, etc.
• Career advice: Explore postdoc strategies for adapting.

Stakeholder Reactions: From Cheers to Concerns

On Zhihu, opinions split: Some hail it as ending "academic cash cows" for Western publishers; others fear talent drain or stifled innovation. Publishers like Springer Nature acknowledge Chinese authors' value but eye adaptations. Gengyan Tang views it as efficiency push, not OA rejection.

Universities in China may follow, amplifying effects.

Evolution of China's Publication Policies

Step-by-step: 2019 Excellence Plan → Warning Lists (2020-) → 2026 APC Ban. Ties to breaking paper mills, promoting quality over quantity. China now leads global output, topping Leiden 2025.

Promising Domestic OA Alternatives

CAS-backed journals like Science Bulletin (no APC, 1区 equivalent) gain traction. By 2023, 178 English OA titles, emphasizing quality. Researchers: Pivot here for funding compliance and impact.

Global Ripples and Precedents

Germany caps APCs at €2,000; NIH proposes limits. Publishers may lower fees or lose China market (key revenue). Positive for sustainable OA.
