四川农村居民消费结构演变分析

Analysis of Sichuan Rural Residents’Consumption Structure Changes

基于四川省1998～2011年农村居民消费统计数据,立足于居民消费类型的八大指标,利用信息熵分别对农村居民消费构成的熵值、均衡度、优势度进行计算和分析.结果表明,居民消费结构的信息熵已从1998年的1.355增到了2011年的1.812,总体上成波动上升趋势,消费结构复杂化了;均衡度由0.652上升到0.871,说明各消费项目之间的比例差别越来越小;优势度则从0.348降到了0.129,反映以食品消费项目占支配地位的居民消费发生了变化.最后针对消费类型现状,提出促进消费、优化消费结构的建议.

Based on the eight indicators of the residents’consumption type and consumption statistics in Sichuan province from 1998to 2011,the entropy,equilibrium degree and dominance are calculated and analyzed.Results show that the information entropy of the residents’consumption structure has increased from 1.355to 1.812,showing an overall wave rising trend,the consumption structure becoming perplexed;Equilibrium degree has risen from 0.652to 0.652,indicating the proportional differences between the consumptions are becoming smaller and smaller;Dominance has declined from 0.348to 0.129,reflecting the degree of residents’consumption which gives priority to food consumption projects has undergone changes.Therefore,the corresponding countermeasures and suggestions are put forward,which is aimed at promoting consumption and optimizing the consumption structure.
