| 中文摘要: |
| 为了使研究主题的分类和可视化效果更为准确和科学,共词分析经常与因子分析、聚类分
析、社会网络分析、多维尺度分析等技术综合使用。相似度可视化方法( VOS) 是对多维尺度方法的改
进,通过VOS 方法的可视化分析能够直观、清晰地展示某一学科的研究主题热点和研究类别。基于
VOS 方法的农业经济学研究主题可视化分析结果表明: 2007—2011 年我国农业经济研究主题可以分为
农民、农村金融、农民收入与粮食生产、农民工、城市化、农村发展6 个类别,其中与“农民”相关的研究主
题是农业经济学关注的热点。 |
| 英文摘要: |
| In order to cluster and map the research topics more exactly and scientifically,co-word analysis combined with
factor analysis,social network analysis or multidimensional scaling analysis are usually applied. The method of visualization
of similarity ( VOS) is an improvement of multidimensional scaling,which can directly and clearly display the categories of
research focuses and research topics. The results of mapping the research topics of agricultural economics by VOS method
show: from 2007 to 2011,the research topics of agricultural economics in China can be clustered into six categories,including
farmer,rural finance,farmers' income and food production,rural migrant workers,urbanization,rural development.
The topics related to farmer are major concerns in the field of agricultural economics. |
