Field-specific gold open access dynamics in the Chinese mainland: Overviews, disparities, and strategic insights

Gold Open Access (OA) journals are crucial for scholarly communication, highlighting the need for a thorough evaluation of their academic influence on different research fields. This study leverages the InCites platform to examine article-level characteristics relating to 22 Essential Science Indicators (ESI) research fields, with a focus on the dynamics of gold OA articles, including gold OA uptake in the Chinese mainland and gold OA adoption in the domestic English-language academic journal publishing of the Chinese mainland. The findings reveal that disparities in gold OA adoption across 22 ESI fields are more pronounced in the Chinese mainland compared with the world scenario. In the Chinese mainland, there is a significant polarization in gold OA publishing volumes across different ESI fields, particularly in Chemistry, Clinical Medicine, and Engineering. This study builds on the understanding of OA citation advantage (OACA) by incorporating gold OA publishing volume into a two-dimensional framework, resulting in the development of a “distance” metric. It further categorizes gold OA citation effects into four quadrants: positive citation effects (quadrants A and B) and negative citation effects (quadrants C and D), based on category normalized citation impact (CNCI) and journal normalized citation impact (JNCI) indicators from the InCites database. The findings underscore the importance of developing tailored strategies to address field-specific challenges and promote gold OA dynamics in the Chinese mainland; while prioritizing high-quality gold OA journals is essential for fostering gold OA development in the rest of the world.
