摘　　要：通过数理模型推导判定社会保障与居民消费存在非线性关系,在城乡经济协调水平由高到低的四阵营划分下,构建多重面板门槛模型,得出:全国的城乡社会保障扭曲与居民消费差距间呈倒"U"型关系,即优化社会保障城乡配置政策存在消费"陷进",第一阵营二者呈负向非线性相关,第二、三阵营二者呈倒"V"型相关,第四阵营二者呈倒"U"型相关。城乡收入和财富差异约束社会保障扭曲对消费差距的影响作用:在城乡收入差异约束下,全国、第一、三、四阵营二者呈"U"型相关,但各自优化社会保障城乡配置必须跨越不同的收入差距门槛;在城乡财富差异约束下,全国二者呈"V"型相关,在跨越城乡财富差异的门槛值0.226之后,优化城乡社会保障支出配置对平衡城乡消费差距才有效率,但四个阵营财富差异对二者关系约束并不显著。We deduce there is a non-linear relationship between social security and consumption of residents by mathematical model. Then,under the division of four camps with the level of urban-rural economic coordination from high to low,we construct Multiple Panel Threshold Model. The conclusions are as follows:(1) There is an inverted "U"relationship between the urban-rural social security distortions and urban-rural consumption of residents. There is a "trap"when we take measures through optimizing the allocation of social security between urban and rural areas to shrink the gap between urban and rural consumption. They are inversely non-linearly correlated in the first camp,and inverted "V"type related in the second and third camp,and inverted "U"type related in the fourth camp.(2) The relationship between the distortion of social security and the disparity between urban and rural areas was affected by the gap of income and wealth between urban and rural residents: Under the income gap between urban and rural residents,the relationship between the distortion of social security and the disparity between urban and rural consumption,is "U"type in China,the first,third and fourth camp,it shows that optimizing social security urban and rural allocation must cross different thresholds of income disparity; Under the wealth gap between urban and rural residents,the relationship is"V"type in China,when the gap between urban and rural residents' wealth across the threshold of 0. 226,we take the policy on narrowing the urban-rural social security spending to balance the gap between urban and rural residents consumption is more effective,but the effect is not significant in four camps.
