In this study, the Input- Output Structural Decomposition
Analysis (I-O SDA) is used to investigate the effects of
technological structure changes on changes of total output in
Sistan and Baluchestan Province during 2006-2011. The
technological structure change is decomposed into two factors:
intermediate input structure changes (input substitution) and
change in direct backward linkage. The results show that the
effect of changes in direct backward linkage is negative in all
sectors, but the effect of input substitution in twelve sectors is
positive and in other nine sectors is negative. Input substitutions
in "Agriculture" and "Transport" sectors have the main positive
effect on total output of the region and in ''Food industries'' and
''Restaurants & Hotels'' have the main negative effect on total
output. This factor caused 20.89 billion Rials decrease in total
output of region. Changes in direct backward linkage caused
8270.89 billion Rials decrease in total output of the region.
