In this article three types of tables followed by a modified table of 2016 of central bank for understanding the changes from the first generation of statistical base to the second generation data base requirements of the new international trade theory are introduced. The third type of table plays a key role and is considered as starting point for such changes. Considering the absence of such a table in Iran, this article raises three issues, followed by three main questions: First, if official compilers do not attempt to compile such a table soon, what solution can be proposed? Second, as compared to the modified tables, which one of the two types of tables has more stastistical errors? Third, in measuring value-added content in gross exports which one of the two tables is preferred? The latest SUT and intermediate import use table of 2016 that are provided by central bank are used to investigate three questions. The overall findings reveal that: The estimate of the third type of table can circumvent Iran. As compared to the second table, the third table has relatively less statistical errors. Finally, as compared to second table, the third table has edge over in measuring value added content in gross exports.
