| 摘 要： | 选取SCI/SSCI收录的国际"农业经济与政策"领域中的10个英文期刊作为研究基础数据,对作者发表论文及合作进行研究。发现作者发文量分布出现明显的"长尾现象",服从幂律分布规律,即少量作者和机构对学科领域的发展做出了大量的贡献,而大量的作者和机构只做出了少量贡献。农业经济与政策领域合作网络中包含大量不相连接的小型网络,处于科研合作网络发展的初级阶段。

| Abstract: | 10 English journals of agricultural economics and policy field indexed by SCI/SSCI were selected as the basic data to study author distribution and cooperation. The author distribution appeared a long tail phenomenon and obeyed the power law distribution,which meant a few authors to make a lot of contribution to the academic development,while a large number of authors only had a little contribution. In the cooperation network,a great deal of the small scattered scale network existed,which might imply the cooperation network in the primary stage. |

| Keywords: | agricultural economics and policy power law distribution yielding authors cooperation |
