中国城镇居民信息消费水平动态组合评价研究

Study on Information Consumption Level Dynamic Comprehensive Evaluation of Urban Residents in China

首先从三个方面分析了城镇居民信息消费水平的分布特征与演进规律，采用核密度估计方法绘制了相应的概率密度函数图，从分布情况来看三个指标具有不同的演变态势。然后基于第一主成分分析方法评价各时间截面信息消费水平，进而以末期较初期的序差和标准差对各省份进行了分类。针对时间权重多采用主观赋权的缺点，采用具有激励特征的主客观组合赋权方法得出最终的评价值和排名顺序，并以信息消费水平组合评价值和标准差对各省份进行了分类。最后，采用非参数检验方法对区域之间的信息消费水平进行了比较。

Firstly, the distribution characteristic and evolution trend are analyzed from three indexes. The probability density function charts are obtained by the kernel density estimation. The distribution evolution trend of three indexes is different. In the first stage, the information consumption level of every time section is estimated by the first principal component evaluation method. Then the develop situation are classified by the conclusion of order difference and standard deviation. In the second stage, based on the subjectivity defect of time weights, the subjectivity and objective combination weights method with incentive characteristic are studied. The evaluation value and order of province in China are obtained by this method. The develop situation are classified by conclusion of evaluation value and standard devia- tion. Finally, the consumption level of three regions is compared by the nonparametric test methods.
