Keep in mind this is lagging indicator of 00s PRC academic reforms where PRC institution building and adding millions more talent into academia. There's been magnitude increase in talent generation, ~5m STEM per year for last several years or roughly OECD combined that's making their way through pipeline while tertiary system continues to expand and improve. I surmise these indexes will get increasingly lopsided going forward.
