However, there were some researchers focusing on these promotion mechanisms and then they got different outcomes. This paper achieves the goal for exploring the influence factors of officials＇ promotion by using OLS empirical test. From collecting the data of Chinese local officials and cities＇ economic conditions, we find that economic performances and political relationships can have a significant effect on officials＇ promotion, but financial performances cannot have this effect. And the experiences and lesson of this research have some reference for exploration of Chinese local officials＇ promotion incentive.展开更多
