Food demand in rural China: evidence from rural household survey
利用中国农村住户调查数据，通过动态AIDS模型估计了农村家庭对大米、小麦等主要食品的需求参数，发现所有食品支出弹性为正，但粮食为必需品，肉类等为奢侈品。
The recent rural reforms in China have had great effects on agricultural production and productivity as well as rural household consumption. While much has been written on production and productivity effects of these reforms, very few Chinese studies have attempted to analyze the changes in rural consumption patterns. This paper uses a dynamic AIDS model to estimate various food demand parameters for Chinese rural households using rural household survey data recently released by the China State Statistical Bureau. The results show that all important food commodities including rice, wheat, coarse grains, vegetables, meat, tobacco and alcohol have positive expenditure elasticities. Rice, wheat and coarse grains are necessities, while meat, vegetables, alcohol and tobacco are luxuries. The expenditure elasticities for rice, coarse grains and tobacco are declining, but those for wheat, meat, vegetables and alcohol are increasing. As per capita income rises and population increases, the demand for these items will continue to increase. Therefore, China must continue to increase its food production by a greater rate in the future in order to avoid food shortages.
