In this paper, the new methods of optimizing genetic algorithm control parameters are presented, including the method of adjusting crossover probability and mutation probability, the dynamic convergence rule and the method of determining the optimal population size.

However, after the US dollar depreciation, the dynamic convergence rate of current account deficits falls firstly, and accelerates subsequently because financial market's response to price information is sooner than goods market' s.

由于金融市场的反应速度快于商品市场，汇率贬值首先会降低经常项目赤字的收敛速度，而后会加大收敛速度。

The dynamic convergence rate of current account deficits determined by the gross rate of return on US assets, trade elasticity value for exchange rate depreciation, the US dollar exchange rate.

而经常项目赤字动态收敛的速度取决于资产收益率、汇率贬值的弹性值和汇率。
