A standardized regression coefficient in a multiple linear regression coefficient, tells you by how many SD units the score on the dependent variable (DV) is estimated to change, per SD unit change on the independent variable (IV) of interest, with the other IV values fixed.
If that's your definition of "net effect," then the answer to you query is "yes."
If you have some other definition for net effect, the the answer is "no."
Of course, please recognize that the resultant standardized regression coefficient depends on the specific sift of IVs in the model as well as your specific sample.
Md. Ayatullah Khan No, the net effect and standardized coefficient are not the same in multiple regression. The net effect is the unstandardized coefficient or regression coefficient, which represents the change in the DV for IV. However, the standardized coefficient is obtained by standardizing both the DV and IDV.
