Prediction at China´s coal production quality based on VEC model early “12 5”

A VEC model which Includes four coherent variables tested by unit test and co-integration test for the study of China´s total amount of coal production was set up, the fitted value for history of the model was satisfactory through tested. The paper predicted total amount of coal production by the model, got important conclusions through the analysis of the simulation results. At last put forward relevant measures and developing goal.
