摘　　要：运用系统动力学与统计学原理相结合的方式描述住房保障水平对恩格尔系数的影响,分析恩格尔系数影响因素的因果回路图,构建保障性住房规模影响恩格尔系数的SD模型并进行仿真模拟,结果表明实施土地供给政策和社会保障性支出政策对保障性住房规模有一定促进作用,并且保障性住房规模的增加对恩格尔系数的降低有促进效应。最后,基于研究结果对提高保障性住房规模和优化消费结构提出相关建议。The combination of system dynamics and statistical principles is used to describe the impact of housing security level on Engel’s coefficient,analyze the causal loop diagram of influencing factors of Engel’s coefficient,construct the SD model of the impact of affordable housing scale on Engel’s coefficient and conduct simulation,The results show that the implementation of land supply policy and social security expenditure policy can promote the scale of indemnificatory housing,and the increase of indemnificatory housing scale can promote the decrease of Engel’s coefficient.Finally,based on the research results,some suggestions are put forward to improve the scale of affordable housing and optimize the consumption structure.
