Household Demand in Rural China: A Two‐Stage LES‐AIDS Model
使用1982-1990年省级面板数据，通过两阶段LES-AIDS模型估计中国农村家庭的完整需求系统，发现食品、服装等商品需求缺乏价格弹性，住房和日用品为奢侈品，食品内部需求增长快于供给，预示中国将面临进口食品压力。
Abstract A complete demand system of Chinese rural households is estimated using a two‐stage LES‐AIDS model and pooled provincial and time‐series data from 1982 to 1990. For commodity groups (food, clothing, fuel, housing, and other commodities), demand is price‐inelastic. Housing and other commodities are luxury goods, while clothing and food are necessities. Within the food group, price elasticities range from −0.005 to −0.63. Expenditure elasticities are lower for grains and higher for meat, tobacco, and alcohol. The results imply a gap between food demand and supply growth. Therefore, China will face pressure to import food.
