消费需求模型及其对贫困和福利统计的改进

Consumer Demand Model and Its Improvement for Poverty and Welfare Statistics

消费需求系统模型是研究消费跨期波动和统计测算贫困问题的基础。近似理想需求系统模型是对消费需求系统模型的改进,使传统依靠宏观数据研究的问题转化为可以依靠大量的、更精确的微观家庭调查数据来更准确地研究。消费模型的改进及其在贫困和福利统计中的应用,以及由此建立的家庭调查数据与相应的统计方法有利于政府对贫困家庭进行更准确地测算和进行跨期和跨地区的比较,从而制定更有针对性的政策来解决贫困问题,实现共享发展的目标。

The consumer demand system model is the basis of studying inter-temporal fluctuations in consumption and the statistical measurement of poverty. Approximate ideal demand （AID） system model is an improvement to the consumer demand system model, and makes the traditional research which relies on macro data rendered into more accurate studies that can rely on large, more accurate micro household survey data. Therefore, the improved consumption model and its application in poverty and welfare statistics, as well as the household survey data and the corresponding statistical methods, are helpful for the government to make more accurate statistics and inter-temporal and trans-regional comparison of poor families, thus formulating more targeted policies to solve the poverty problems and achieving the goal of shared development.
