Analysis of the Changes in China's Grain Production Costs over the Past Decade

China's grain production cost has risen constantly since 2003. This paper starts from the grain production cost changes of unit area and unit quality, to analyze the reasons for China's grain production cost change in the last decade. It points out that the direct cause of changes in grain production cost is the steady growth of material and services costs, the fastest growth of labor costs and fast growth of land costs. The indirect cause of grain production high cost is the low efficiency in numerous and dispersive farmer production management, obviously insufficient agricultural infrastructure construction, waste phenomenon grain in production process and low contribution rate of agricultural technology. On this basis, it is recommended to reduce China's grain production cost and improve grain production conditions.
