                 CCCI and Exports   As far as export are concerned, we use Net Exports
             as its representative indicator. There is an important resonance relationship
             between CCCI and NE with short, medium and long variation period, which
             are interdependent and mutually restrictive. In the short resonance period
             of 4 months, the phase leads of CCCI is nearly one month ahead of NE. In
             the  medium  resonance  period  of  15  months,  CCCI  has  a  phase  of  2.03
             (about  4.8  months)  leading  variation  trend  of  NE.  Furthermore,  a  phase
             leads about 10.7 months occurs in the long resonance period of 30 months.
             However, in the resonance periods of 6-8 months, CCCI lags behind NE for
             less than one month. The moral is that, there is a strong correlation between
             CCCI  and  NE,  and  CCCI  has  a  certain  explanatory  power  to  the  future
             variations of Net Exports.

            considers two important representative variables, RSCG and CPI. RSCG is the
