Modifying Adjusted Flag Location Quotient (AFLQ)(A case study o Tehran province)

Location quotient is a non-statistical method which brakes technical coefficient and uses some especial treatment to adjust them for regional studies. This method has evolved during the time and its latest version is known as augmented AFLQ based on specialty sector. This article attempts to challenge this method by using the data of Tehran Province (2007) as a case study underlining the crucial cracks in it. This crucial crack is inability in truly adjusting backward linkage of the demand of weak sectors which make regionally weak sectors wrongly being considered as the key sectors of the demand side. At last, a method will be presented much more accurate in converting national table to regional table in which this crucial crack has been resolved.
