The Analysis on Consumption Structure of Residents in China
Abstract：In recent years, the gap between urban and rural areas in China to gradually expand the trend, which is the most significant differences between urban and rural residents in the consumption structure, this paper selects the annual statistical data of 1990-2013, in the consumption structure of urban residents as an example, by using multiple linear regression model and ELES model, the Engel coefficient of urban residents' consumption structure of China's empirical analysis. The results show that the concept of consumption, income, social security system and other aspects of the different, resulting in the significant differences exist in the consumption structure of urban and rural residents in china. In order to narrow the gap between urban and rural areas, we should take the following measures: narrowing the income gap between urban and rural areas, vigorously develop the rural consumer goods market,accelerate the process of city, improve the city level, the deepening of social welfare system.

我国城乡居民消费结构分析
引言
消费结构是指消费者在不同商品的支出占总的消费的比重，其中也包括他们之间的相互联系。消费结构既受消费水平制约又推进它的进步。因此，消费结构是反映消费者消费的重要指标。由于我国城镇的经济发展水平高于乡村，城镇居民的消费引领了我国消费的方向和发展趋势。但随着城市化进程的加快，农村居民的消费结构在逐步得到优化，可以看出接近于城镇居民的趋势。但城乡消费结构之间依然有差距，影响城乡居民消费支出差异的因素可能有很多，例如，居民收入，社会保障制度等。为了研究我国居民消费结构差异的原因，需要做出具体的分析。
