Chinese cotton industry economy monitor and the early warning indices- Chinese cotton production prosperity index (CCPPI) and the Chinese cotton growth index (CCGI) have been used for cotton monitoring at a national scale. And their composition, the forecast and the monitor real diagnosis function and the effect in early warning system for cotton industry economy are also analyzed.
