On the Reverse Fluctuated Relationship between Grain Output and GDP
The paper explores into the relationship between the grain output and output value of second and third industry by using co-integration test and ECM based on 57 samples from 1952 to 2009. The analysis shows that the fluctuation of the output value of second and third industry leads to the reverse fluctuation of grain output, the short-term elasticity of which is -0.24. The conclusion supplies a special perspective for the formulation of grain macro -control policy.
