基于改进群组层次分析法的进城定居农民生活满意度评价

Evaluation of the life satisfaction of urban settled farmers based on improved group analytic hierarchy process

依据研究问题的实际背景,应用抽样技术中的分层抽样和二重抽样,依次获得初选专家组和复选专家组。从保序性原则出发,计算复选专家组排序权重向量的绝对差值,按照规定阈值对专家组意见一致性进行检验,获得最终专家组,改进群组评价。以地级市为研究对象,构建进城定居农民生活满意度递阶层次评价模型,考虑数据的可得性,在商洛市采集样本数据,分别用改进群组评价及熵权法获得主客观权重及组合权重,应用模糊综合评价计算指标满意值及综合满意值。结果表明,改进群组层次分析法权重与组合权重排序一致性较高,商洛市进城定居农民生活满意度处于一般和基本满意之间,为地级市城镇化建设提供了参考。

In terms of the actual background of the research,the elementary and secondary selection expert groups are obtained suc⁃cessively by using both the stratified and double sampling of the sampling technique.The absolute difference of the ranking weight vec⁃tors of the secondary selection expert group is calculated on the principle of rank preservation,and the unanimous opinions of the ex⁃pert groups are verified based on the prescribed threshold,to obtain the final expert group and improve the group’s evaluation.Taking prefecture-level cities as the research object,the model of hierarchical evaluation on life satisfaction of urban settled farmers is con⁃structed with the consideration of the availability of data.The sample data is collected in Shangluo city,the subjective-objective weight and combined weights are gained by improving the group’s evaluation and the entropy weight methods respectively.The index and comprehensive satisfaction values are calculated by using the fuzzy comprehensive evaluation.The results show that the improved group’s hierarchical analytic weights and the combined weights have a high ranking consistency.The settled farmers in Shangluo city have the general and basic life satisfaction,providing a reference for the urbanization of the prefecture-level city.
