Based on all the researches available, this paper simulates a more general ARIMA(0,1,q) process and analyzes the influence of lag length selection criterions to the size and power of the ADF test with different data generating processes, ADF regressions, and sample sizes. Finally, it is proved that the Modified Information Criteria always shows a more proper size and the General to Special Criteria has more robust properties in ADF test.

本文在已有研究的基础上，模拟了更为般的ARIMA(0，1，q)过程，分析了在不同的数据生成过程、检验式以及样本容量下，各种滞后长度选择方法对ADF检验功效和实际检验水平的影响，最后以为修正的信息准则通常具有较合理的实际检验水平，而从般到特殊法具有更为稳健的ADF检验性质。
