Group 1 - A gray industry chain has emerged in China, offering "invisible retraction" services to delete published papers from databases for fees ranging from hundreds to tens of thousands of yuan [2] - A study led by Professor Adrian Barnett from Queensland University of Technology found that over 250,000 cancer research papers published between 1999 and 2024 are suspected to be products of "paper mills," with over 170,000 from Chinese institutions, accounting for 36% of China's total cancer paper output during that period [2][3] Group 2 - The prevalence of low-quality papers, referred to as "water papers," is attributed to the "four only" evaluation system in academia, which emphasizes only papers, titles, degrees, and awards, leading to a focus on quantity over quality [3][4] - The rise of generative artificial intelligence has made it easier to produce "water papers," raising concerns about the dilution of research quality and the urgency to address this issue [4] - The Chinese government has recognized the problem and initiated reforms to the talent evaluation system, aiming to shift focus from the "four only" approach to a system that values innovation, capability, and contribution [4][5]
