The results of the hierarchical regression model are
presented in Table 4. Model 1 includes the control
variables and the two explanatory variables reflecting
offshoring complexity: configuration complexity
and task complexity. We add the two moderating

and offshoring experience—in Model 2. In Model
3, we add the interaction effect between the two
complexity variables and our two moderating variables.
这段文章来自Strategic management Journal,就是使用hierarchical regression model,为什么就是正确的呢?
