财政政策与微观经济体之间的动态影响关系对当前研究居民消费行为具有显著意义,它基于拉姆塞-卡斯-库普曼模型的成果分析2003-2011年重庆地方政府购买支出对城市与农村不同收入等级家庭的食品、衣着等消费类别的影响,得出食品消费在居民消费结构中占据了最重的份额,其与家庭设备用品与服务及医疗保健由于其固有的刚性需求,财政购买支出变动对食品消费、家庭设备用品与服务及医疗保健其影响并不显著,对衣着消费的挤出效应显著且城乡衣着消费偏好不同,政府支出的提高可以降低家庭在娱乐教育文化的消费支出,但会提高居民在居住项目上的支出。 The dynamic relationship between fiscal policy and microeconomy is significant for current research on household consumption behavior. Based on the results of Ramsay-Kath-Koopman model, Rural households with different income levels, such as food, clothing and other consumer categories, come to the conclusion that food consumption occupies the heaviest share of the household consumption structure, and household appliances and services and health care due to its inherent rigid demand, financial purchases Expenditure changes have no significant effect on food consumption, household equipment, supplies and services and health care. The crowding-out effect on clothing consumption is significant and the preferences of clothing consumption in urban and rural areas are different. The increase of government expenditure can reduce the consumption expenditure of the family in entertainment, education and culture, However, it will raise residents’ expenses on living items.
