综述了估计等价规模和计算等价收入的经济理论、方法体系和量化指标,并基于我国国情及相关调查数据的现实情况建立了一套有效的模型测算工具,以此为基础对我国居民收入的等价规模进行了测算。结果表明,我国的等价规模指标与国际已有研究结果存在较大差异,特别是表现在“我国抚养子女的规模经济效益并不显著”以及“老龄人口必须纳入我国家庭规模经济测算框架”两个方面。本文提供的研究框架、建模方法和测算结果有助于为我国精确刻画以家庭福利为基准的收入分配状态,基于家庭消费支出结构的计算方式能够帮助管理者有效地设计和实施家庭收入扶植计划,另外,研究结果对于收入差距的测算以及贫困线的划定等问题有着理论界定和实际测算的指导意义。
The economic theory, method system and quantitative index for estimating the equivalent scale and calculating the equivalent income are summarized. Based on the actual conditions of our country and related survey data, an effective model calculation tool is established. Based on this, The equivalent scale was calculated. The results show that there is a big difference between our country’s equivalent scale index and the international research results, especially in the fact that “the scale economic benefits of raising children in our country are not significant” and “the elderly population must be included in our country’s family scale economic calculation Framework ”two aspects. The research framework, modeling methods and measurement results provided in this paper contribute to accurately characterize the state of income distribution based on family welfare in our country. Based on the calculation of household consumption expenditure structure, managers can effectively design and implement the household income support plan In addition, the results of the study have theoretical significance and practical significance for the measurement of income disparity and the delineation of the poverty line.
