Abstract: At present, the agricultural products’supply in Xi''an can not meet the demands of urban and rural residents on consumption structure upgrading, agricultural production faces the two-way pressure from cost and price of agricultural products, and the old way of obtaining agricultural products at the price of ecological environment can not be accepted now. In order to study the development status and existing problems of the structural reform of agricultural supply side in Xi''an, we investigated major food producers, cooperatives of grain, fruits and livestock, and analyzed the status quo of Xi''an’s agricultural development. Finally, we proposed suggestions, such as adjusting agricultural structure, improving agricultural production mode, reducing production cost, integrating the primary, secondary and tertiary industry, enhancing agricultural service ability, upgrading sales modes of agricultural products, and promoting the modernization of agricultural production facilities, for Xi''an’s agricultural supply side structural reform and government decision-making.
