Comparative study on the change trends of urban and rural consumption structure in Anhui province

The urban-rural gap is a major problem that exists objectively at present，and the urban-rural consumption gap is one of its concrete manifestations. The consumption system is very complicated and easily affected by the change of internal and external factors，and different characteristics are presented in different periods and regions. Comparing the urban and rural consumption structure，analyzing the causes of change and narrowing the consumption gap is of great significance to balance urban and rural development. According to the Engel’s coefficient，the period of 2002-2016 is divided into three stages. Calculate the gray correlation between the per capita consumption and the consumption items of town and country of Anhui in each stage with the gray system theory. Analyze the trends and causes of urban and rural consumption structure. Then build GM（ 1，1） model to analyze the future development trend of urban and rural consumption structure. Finally the reference opinions are given to make consumer policy. The study finds that the rural consumption level is obviously lower，and the differences between urban and rural consumption will exist in the present and future for a long time，and the consumption structure has been optimized gradually，but the process has a certain degree of repeatability and volatility.
