| 摘 要： | 恩格尔系数可以反映居民生活水平，也隐含着经济结构的信息。本文采用非线性定量分析工具——分形分析方法，通过各阶累计和将数据进行变换，建立变维分形模型，测算了1995～2008年我国农村居民恩格尔系数的变化趋势。研究表明，样本区间内农村居民恩格尔系数整体有降速放缓的趋势，前期降速显著，后期降速减缓；且依据模型测算显示未来5年内这种趋势将可能持续。最后，本文据此提出了简短的对策建议。

| Abstract: | Engel＇s coefficient can reflect the resident＇s living standard, and the economic structure of implicit information. This paper adopted a quantitative analysis tools-fractal analysis method, through cumsum data transform, established the fractal dimension change model, and then estimated the 1995-2008 China rural residents Engel＇s coefficient of variation trend. Research showed that the sample range of rural residents Engel＇s coefficient slowed down, the trend of speed slowed down significantly at the first stage, and later, its speed was slow. According to the next five years model and measurement information, this trend would continue. Finally, this paper presented a brief countermeasure and some suggestions. |
