Output counts: comparing the published contributions by agricultural economists across countries
利用SSCI数据比较1987-97年德国、荷兰、英国和美国农业经济学教授的人均发表量和被引次数，发现德国人均贡献和引用均显著低于其他国家。
Agricultural economics research is an international endeavour that benefits from the free exchange of knowledge. Using data from the Social Science Citation Index (SSCI) we compare for the period 1987-97 the published contributions by agricultural economics professors from universities in Germany, the Netherlands, the UK and the US, and we measure citations. There are considerable differences in the contributions per capita to the international journal literature and in citations received. Germany has contributed much less per capita than the other countries and its agricultural economists have received fewer citations. The percentage distributions for articles and citations are remarkably similar across countries. Copyright 1999 by Oxford University Press.
