Paper Tiger? Chinese Science and Home Bias in Citations, NBER working paper
    We investigate the phenomenon of home bias in scientific citations, where researchers disproportionately cite work from their own country. We develop a benchmark for expected citations based on the relative size of countries, defining home bias as deviations from this norm. Our findings reveal that China exhibits the largest home bias across all major countries and in nearly all scientific fields studied......Our adjusted ranking places China fourth globally, behind the US, the UK, and Germany, tempering the perception of China’s scientific dominance.
