3、素,并选取收 入水平、滞后一期消费量、乳品价格指数、肉禽及其制品价格指数和 蛋类价格指数五个主要因素进行岭回归估计。 本文采用双对数模型对 时间序列数据进行回归估计,分别得到城镇和农村居民乳品消费的需 求弹性、收入弹性、消费习惯影响弹性和交叉价格弹性。最后结合制 约中国居民乳品消费的因素分析,提出提高消费水平的政策措施,主 要以政府、乳品加工企业、行业协会和消费者四大主体的行动来改善 当前乳品消费现状,不断努力提高中国的乳品消费水平。【英文摘要】 With the rapid developme nt of the economy in China, the residents livings
