We choose different number of knowledge types and see how knowledge breadth would affect the hypotheses ? Stepwise analysis that removed one knowledge category ranked the least important by experts at a time, and repeated the path analysis for 9 times.

IT affects the intensity and diversity of anizational knowledge ? Higher knowledge intensity improves the average firm performance but reduces the stability (increases variance) ? Higher knowledge diversity reduces firm performance, but increases performance stability
