On base of information systemic theory, this paper studies impact from business information system on dynamic capacity of firm, through data analysis from questionnaire, we get results that business information system(BIS) significantly influence on dynamic capacity(DC), management level of firm takes partial function of mediator when BIS impacts on DC, and study atmosphere takes significantly negative function of moderator both as BIS impacts on management level or DC and management level influences on DC. We find that when use time of business information system and use quality of business information system take function together, use quality of BIS mainly take function on DC yet use quality and use time of BIS have mutual substitution effect. BIS influences on DC limitedly, other factors reduce percentage of impact from BIS on DC (slope) by mean of study atmosphere. All these give insight to BIS and DC of firm and meaningful suggestion to managers.
