粮食主产区农村居民食物消费行为的计量分析

“民以食为天”,食物消费是人类生存和发展首要的物质基础。农村居民的食物消费水平是决定农村居民身体健康的物质基础,是农村居民生活水平的重要标志。研究和掌握食物消费结构特征,有利于农业产业结构调整和制定正确的农业产业政策,从而促进农民增收,实现农业的可持续发展。粮食主产区的粮食产量占全国粮食总产量的60%以上,对中国的粮食供给和安全具有举足轻重的作用,增加主产区农民收入有利于提高农民种粮食积极性,保证中国的粮食供给和粮食安全。为此,借助几乎理想的需求系统模型(Almost Ideal Demand System,简称AIDS),建立联立方程…

The Mathematical Statistical Analysis of Food Consumption Activities of Rural Residents of Main Grain Producing Areas

With the development of the rural economy in China, rural household's consumption behavior in main grain producing area has being changed, which influence the adjustment of Agricultural industrial structure and agricultural industrial policy. In this article,we use Almost Ideal Demand System(AIDS) to estimate the elasticities of demand expenditure and price(own price elasticity and cross-price elasticity) and then to analyze food consumption behavior of rural household in main grain producing area. The results show that foods such as rice, wheat, pork, beef in main grain producing area have the positive elasticities of demand expenditure. According to the cross-price elasticity, the demand for eggs, mutton, beef and pork is more affected by the fluctuation of other food's price, while the demand for the wheat, rice, maize and soybean is less affected by thefluctuation of other food's price. Based on the results, some policy recommendations, such as increasing farmer's income, expanding the animal food production, stabilize food's price, are put forward correspondingly.in the article.
