Abstract

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. This stands in contrast to the pattern of home bias for China’s trade in goods and services, where China does not stand out from most industrialized countries. After adjusting citation counts for home bias, we demonstrate that China’s apparent rise in citation rankings is overstated. Our adjusted ranking places China fourth globally, behind the US, the UK, and Germany, tempering the perception of China’s scientific dominance.
纸老虎吗?中国科学与引文中的本土偏见
我们调查了科学引文中的家乡偏见现象,即研究人员不成比例地引用来自自己国家的工作。我们根据国家的相对大小制定了预期引用的基准,将家乡偏见定义为对该规范的偏离。我们的研究结果表明,在所有主要国家和几乎所有研究的科学领域,中国都表现出最大的家乡偏见。这与中国商品和服务贸易的本土偏见形成鲜明对比,中国在大多数工业化国家中并不突出。根据本土偏见调整引文数后,我们发现中国在引文排名上的明显上升被夸大了。在我们调整后的排名中,中国在全球排名第四,仅次于美国、英国和德国,这缓和了人们对中国科学主导地位的看法。

期刊介绍: The Journal of International Economics is intended to serve as the primary outlet for theoretical and empirical research in all areas of international economics. These include, but are not limited to the following: trade patterns, commercial policy; international institutions; exchange rates; open economy macroeconomics; international finance; international factor mobility. The Journal especially encourages the submission of articles which are empirical in nature, or deal with issues of open economy macroeconomics and international finance.
