In Iran, the Symmetric Input-Output Tables (SIOTs) are calculated by two Institutes i.e the Central Bank (CB) and Statistical Center of Iran (SCI). The Central Bank always supports the industry technology assumption in order to avoid emergence of negative elements, the challenges facing their removal and re-balancing of the SIOT. On the contrary, Iran Statistical Center was initially in support of the same technology assumption, while in 2001 it placed the phrase” mainly commodity technology assumption with some adjustment based on the mixed technology assumption” as the basis for calculation of its symmetric table. Findings of the paper indicate that different interpretations of technology assumption and modifications conducted by such institutes lead to different policy implications on the priority of sectoral investment. Also adjustment made by the SCI is more considerable than that of the CB. This same issue has not only led to notable differences in the incremental coefficients of goods production, but also has changed investment priority among commodity groups.

Using different technology presumptions by Central Bank and Statistical Center of Iran in designing symmetric tables has confused the users. Users have two solutions for this problem: using the symmetric tables irrespective of the technology presumptions in different economic areas or calculating them based on make-use matrices proportionality to specific goals before using. The article addresses the later. Eight symmetric tables are calculated based on last aggregated statistical make-use matrices designed by Central Bank and Statistical Center of Iran in 1999 and 2001 and are compared with the present tables emphasizing the production structure of petroleum and natural gas. Findings of the research reveal that all elements of the mentioned tables are meaningful and should not easily be modified and removed.
