利用ELESM分析贵州城镇居民消费的各种弹性

Using Linear Expenditure System Model to Analyze Consumer Demand Elasticity of Guizhou Urban Residents

众所周知经济学中的弹性有需求价格弹性、需求收入弹性等,其中需求价格弹性还包括需求自价格弹性和需求交叉弹性。对弹性的实证分析,可以帮助我们正确认识和把握收入变动和价格变动对商品需求量变动的影响规律,对搞活微观经济促进城镇居民消费结构的转变起着积极作用。利用扩展的线性支出系统模型,以贵州统计年鉴(2002)公布数据为样本,以2001年为典型,对贵州城镇居民消费需求的弹性进行实证分析,合理求出各种弹性。

In economics,demand elasticity consists of price elasticity and income elasticity of demand. Price elasticity also includes self- demand elasticity and the cross- elasticity of demand. The empirical analysis of flexibility can help us to correctly understand and handle the rules of the commodity demand under the impact of the changes in income and commodity price changes,and can play an active role in enlivening mieroeconomic structural changes and promoting the consumption of urban residents. Using expanding linear expenditure system model, Taking Guizhou Statistical Yearbook （2002） published data for samples,especially 2001,the writer is trying to analyze consumer demand for flexible to figure out reasonable various flexibility.
