The forecast for the share of corresponding/leading authors in scientific publications in chemical engineering in Japan shows a slight but steady decline from 94.11 in 2024 to 93.8 in 2028. The trend reflects a gradual reduction, with each year marking a decline of approximately 0.08. Comparatively, in 2023, this share was not far from the 2024 starting point, indicating stable but gently decreasing trends. Over the five-year period, the compound annual growth rate (CAGR) reflects this consistent downward trajectory.
Future trends to watch for include potential shifts in collaborative dynamics, possibly influenced by international partnerships or changes in research funding and policy directions. Monitoring any accelerations or decelerations in this decline could forecast broader structural changes in Japanese chemical engineering research authorship practices.
