Abstract
Some industry export competitiveness indices are dependent on the first-order moments of the data but not the second-order moment. As the main form of second-order moment, variances can be used for evaluation of export competitiveness. According to the conditional variance of exports growth rate and the GARCH models, industry export competitiveness can be divided into three categories: strong, General and weak States. Using the GARCH models for export competitiveness research can meet the need of horizontal comparison and longitudinal analyses. The empirical study of the export competitiveness of wind energy industry among some nations have shown that, it is feasible and effective for using GARCH model method to study on export competitiveness.
