According to the problem that there are not consider the issue of time and space factors,when the phenomena are analysed by Geographically and Temporally Weight Regression,(GTWR).the paper,proposes a new method that the method of selecting GTWR variable based on stepwise regression.Based on the stepwise regression,the paper analysis the distribution and its influencing factors in the Shanxi-Gansu-Ningxia region by introducing Akaike's information rule as an example.The experimental results show that the method of selecting GTWR Based on Stepwise Regression is superior to the traditional stepwise regression,forward and backward method.The research results haves a new variable selection method for GTWR analysis.
