基于GRA法的家庭人口结构与食品消费关系研究

Research on the Relationship Between Family Population Structure and Food Consumption By the Method of Grey Related Analysis

利用清华大学中国金融研究中心的3 122份有效微观调研数据,对家庭人口结构与食品消费的关系进行灰色关联分析。结果表明,人口结构中的相对指标与家庭食品消费支出的灰色关联序是:退休人数比重>学前人数比重>上学人数比重>小孩数量比重>工作人数比重>失业人数比重。从家庭人口结构的绝对量来看,与家庭食品消费的灰色关联序是:小孩数量>失业人数>退休人数>上学人数>学前人数>工作人数。在制定拉动国内食品消费的政策时,应该充分考虑到家庭人口结构的影响。

Based on 3 122 micro survey data of China financial research center of Tsinghua university, this paper analyzes the relationship between the family population structure and food consumption by the method of grey relational analysis. The re-sults follow that Grey incidence order of relative index of population structure and the proportion of expenditure on food to the total expenditure of households is as follows：the proportion of retired people﹥the proportion of preschool number﹥the pro-portion of school number﹥the proportion of children number﹥the proportion of worker number﹥the proportion of unemployed number. From the perspective of absolute quantity of the family population structure, the grey incidence order and family food consumption is： the number of child ﹥the number of unemployment﹥the number of retired﹥the number of school﹥the number of pre-school﹥the number of worker. More attention should be paid on the impact of family population structure to food con-sumption, when the government make policy to stimulate the countryˊs economic.
