The issue of the Spatial Economic Dimensions (SED) in generating regional Input-Output Coefficients (RIOC) has been well documented and recognized in the regional analysis since the 1950s.However, this issue has been overlooked here in Iran.In this article, we focus on two main aspects: First, we highlight the factors of SED in generating RIOCs, and the second we quantitatively analyze the relationship between them.
To this end, we use seven non-survey location quotient methods click here in generating RIOCs for 28 provinces.The results portray that if the specialized (or local) sector is considered as an additional factor, the relation between SED and RIOC can be meaningful.
