An assessment of the current structure of food demand in urban China
利用五个省份的家庭支出调查数据，通过分数logit模型和二次几乎理想需求系统，分析了城市家庭在家和在外食品支出的分配及12类食品的替代互补关系。
Abstract We evaluate the current structure of food demand in urban China by using household expenditure survey data from five provinces. Two complementary analyses are undertaken. First, an aggregate analysis based on a fractional logit model is used to examine how households allocate food expenditures across the food‐at‐home (FAH) and food‐away‐from‐home (FAFH) categories. This is followed by a disaggregated analysis of how households allocated their FAH expenditures across 12 commodity categories. A Quadratic Almost Ideal Demand System (QUAIDS) is used. We find evidence of significant food purchase substitution and complementarity.
