本文采用英国经济学家Ｒ．Ｓｔｏｎｅ（１９５４）提出的线性支出系统模型，利用江苏农民需求截面数据，研究和分析了江苏农村居民消费结构。论文首先从计量经济学和江苏农村居民消费特点角度提出建立江苏农村居民需求线性支出系统的理由；论文其次对线性支出系统相关参数进行了公式推算；第三，论文对江苏农村居民需求线性支出系统参数进行了估计；第四，论文利用建立的江苏农村居民需求线性支出系统测算了江苏农村居民需求的生活消费总支出弹性和需求的价格弹性（包括需求的价格弹性和交叉价格弹性），并基此分析了江苏农村居民消费结构；最后，论文提出了优化江苏农村居民消费结构措施
This article uses the British economist R. Stone (1954) proposed a linear expenditure system model, the use of cross-sectional data of farmers in Jiangsu Province, research and analysis of the consumption structure of rural residents in Jiangsu. Firstly, this paper proposes the reasons for establishing a linear expenditure system for rural residents in Jiangsu from the perspectives of econometrics and the characteristics of rural residents in Jiangsu Province. Secondly, this paper makes a formula to calculate the relevant parameters of linear expenditure system. Thirdly, The fourth one is to estimate the total cost of living expenditure and the price elasticity of demand (including the price elasticity of demand and the cross price elasticity) of the demand of rural residents in Jiangsu based on the established linear expenditure system of rural residents in Jiangsu Province, This analysis of the consumption structure of rural residents in Jiangsu; Finally, the paper proposed measures to optimize the consumption structure of rural residents in Jiangsu
