线性支出系统及其在我国的应用

研究我国城市居民家庭支出模式是有意义的。本文采用线性支出系统和广义线性支出系统,建立了我国城市居民家庭支出结构的数学模型。线性支出系统有助于人们搞清价格在家庭对各种商品支出份额配置上的作用和影响。根据线性支出系统和广义线性支出系统,我们求得价格弹性、交叉价格弹性和收入补偿价格弹性等。文章最后部分,我们对改善我国城市居民家庭支出结构提出一些建议。

The Linear Expenditure System and Its Application in China

It would be interesting and useful to study the urban household expenditure patters in China. With the linear expenditure system and extended liuear expenditure system, we build, in this paper, mathematical models of the urban household expenditure structure in China. The linear expendituvre system can help in understanding the role of prices and their effects on the household allocation of expenditure for various commodities. In accordance with the linear expenditure system and the extended linear expenditure system, we find out price elasticity, crosselasticity and income compensation price elasticity and so on. In the end part of this paper, we put forward several pieces of suggestion which are helpful in reforming and promoting the urban household expanditure patters in China.
