为了分析居民的消费结构,本文建立了线性支出系统模型,利用2009年截面数据并通过普通最小二乘法求得模型参数,然后进行了相应的模型检验,最终证实模型可靠。接着利用已求得的模型,算出居民对各类不同消费品的基本消费支出、各类基本消费支出占总基本消费支出的比重等,最后利用上述指标进一步分析居民消费结构,以及居民的生活质量。
In order to analyze the consumption structure of residents, this paper established a linear expenditure system model, using the 2009 cross-section data and the ordinary least-squares method to obtain the model parameters, and then carried out the corresponding model test, and finally proved the model is reliable. Then we use the model we have obtained to calculate the residents ’basic consumption expenditures on various consumer goods, the proportions of various basic consumer expenditures to the total basic consumer expenditures, etc. Finally, we use the above indicators to further analyze the household consumption structure and the residents’ quality of life.
