基于LA-AIDS模型,对福建省1995-2011年城乡各类消费支出及价格的相关数据进行有约束条件的迭代SUR回归,并计算出了城乡的支出弹性、自价格弹性及交叉价格弹性。结果显示:福建省城乡居民各类消费的支出弹性都大于0;食品和家庭设备及维修服务均为生活必需品且为替代品;在交通通讯和娱乐教育文化两类支出上城乡差异较大;在居住消费支出上表现出了属性上的差异。据此,从拓宽收入、引导消费、稳定物价三个方面构造了城乡差异化的消费扩张机制。
Based on the LA-AIDS model, the constrained iterative SUR regression was used to analyze the data of various types of consumer spending and prices in urban and rural areas of Fujian Province from 1995 to 2011, and the urban and rural expenditure elasticity, self-price elasticity and cross-price elasticity were calculated. The results show that the expenditure elasticity of all kinds of urban and rural residents in Fujian Province is greater than 0; food and household equipment and maintenance services are both necessities and substitutes; urban and rural areas differ greatly in both types of expenditure on transportation, communication and entertainment education and culture; Household consumption expenditures showed a property difference. Accordingly, from the expansion of income, guide consumption, price stability three aspects of the construction of urban-rural differences in consumer spending expansion mechanism.
