摘　　要：基于消费效用和资产效用的假设,证明了居民在消费和投资分配上最优均衡点的唯一存在性,由此构建居民微观效用函数;结合反映分配的洛仑兹曲线进一步推导出国民总效用(GNU)函数一般形式,利用统计数据估计出中国国民总效用函数,并进一步计算出历年中国国民总效用(福利)的增长情况,分析其与国民收入增长的差异及原因。结果显示中国历年的经济增长并不能带来国民福利的同步增长,其原因包括居民收入分配不均、消费比重下降、物价上涨等。Based on the hypothesis of consumption utility and capital utility,the paper testifies the existence of the sole point of equilibrium between consumption and investment,and constructs a resident micro-utility function.It further derives a general gross national utility function combining with Lorenz curve,and exploits it to simulate national utility function in China with the statistical data.Furthermore it calculates the national welfare growth over the years,and analyses the difference and reason between national welfare growth and GNP growth.The result indicates the GNP growth had not brought about corresponding resident welfare growth,it attribute to the uneven distribution of wealth,the decrease of the ratio of consumption to GNP,and the inflation of prices,etc.
