消费者收入水平是影响农产品消费需求的主要因素.农产品需求收入弹性的大小反映农产品需求量随收入变化而变化的情况,从而分析农产品对居民生活所产生的影响.本文从单因素方差分析入手分析不同收入水平下的城镇居民农产品需求的差异,考虑收入的不同水平对居民的消费行为产生的影响,为了消除年份差异而引入虚拟变量,建立变弹性的需求函数模型,得到农产品需求收入弹性的定量分析结果,并将该结果与单因素方差分析的结果比较,得到城乡居民农产品消费需求的差异之处,从而提出扩大农产品需求的建议。
The level of consumer income is the main factor affecting the consumption demand of agricultural products.The income elasticity of demand for agricultural products reflects the change of demand for agricultural products with the change of income so as to analyze the impact of agricultural products on the residents’ life.This article starts from the analysis of one-way ANOVA Differences in demand for agricultural products of urban residents at different income levels, taking into account the impact of different levels of income on household consumption behavior, introducing dummy variables to eliminate year differences, and establishing a flexible demand function model to obtain the quantitative elasticity of demand for agricultural products The results are compared with the results of one-way analysis of variance to find out the differences between urban and rural residents in the consumption demand for agricultural products and put forward proposals to expand the demand for agricultural products.
