浙江农村居民消费支出系统函数的稳定性检验

从1983年到2007年,浙江农村居民的消费结构发生了很大的变化,但是模型参数稳定性检验表明,构成需求系统的八个消费支出等式中,只有衣着、家庭设备用品及服务、交通和通讯、文教娱乐用品及服务、杂项类消费支出五个等式发生了短暂和小幅的结构性变化,食品、居住、医疗保健类消费支出等式保持稳定。因此,总体来看,这段时期浙江农村居民的消费行为本身并没有发生显著的变化。显然,农村居民消费结构的变化主要归因于价格和收入的变化,而非偏好的变化。

Testing the Parametric Stability of the Demand System of Zhejiang Rural Residents

From 1983 to 2007,the consumption structure of Zhejiang rural residents has gone through great changes. But parametric stability test shows that,among the eight consumption expenditure equations that comprise a whole demand system,only the equations for clothing,household facilities and services,transportations and communications,miscellaneous commodities and services,as well as cultural,educational and recreational articles and services have witnessed a local and temporary structural change. The other thre...
