【摘要】：目的本研究旨在测度收入和其他社会经济变量如家庭规模对食品和营养需求的作用。方法这项研究使用最近的国家统计局农村调查数据,测度中国农村家庭的食物和营养的需求;线性近似几乎理想的需求系统(LA/AIDS)是用来估计价格和支出弹性,以及社会经济变量对粮食需求模式的影响。然后,使用一个基于广义工具变量方法分析营养需求的决定因素。结果结果表明,收入和其他社会经济变量对食物和营养的需求产生显著的影响。营养需求的支出弹性范围从蛋白质的0.34到胆固醇的1.10。结论这些结果反映食品组的高支出弹性几乎随着收入的升高而同步增加。
[Abstract]:Objective to measure the effects of income and other socio-economic variables such as household size on food and nutrition needs. To measure the food and nutrition needs of rural households in China; the linear approximate almost ideal demand system, La / AIDS, is used to estimate price and expenditure elasticity, as well as the impact of socio-economic variables on patterns of food demand. A method based on generalized tool variables is used to analyze the determinants of nutritional requirements. Income and other socio-economic variables have a significant impact on the demand for food and nutrition. The expenditure elasticity of nutritional demand ranges from 0.34 of protein to 1.10 of cholesterol. Conclusion these results reflect the high expenditure elasticity of food group. As income rises, it increases simultaneously.
