therefore, the purpose of this study is to first exam the relationship between big data characteristics and firm decision quality.

second, investigates the relation mediated by knowledge hiding behaviors.

the findings of this study confirm that big data characteristics increase levels of knowledge hiding behaviors and have a significant on decision quality.

in addition, knowledge hiding behaviors significantly mediates the relationship between decision quality and decision quality.
