Index	Formulae	Citation
Salaee Coefficient of Relative Structural Disparities	$k = \sqrt{\frac{\sum {[\frac{(d_{i 1} - d_{i o})}{(d_{i 1} + d_{i o})}]}^{2}}{n}}$ where di1 dio share of industry i in in the indicators comparable years' structure; n – the number of industries.	Love (2003)
Ryabtsev Index	$I_{R} = \sqrt{\frac{\sum {(d_{1} - d_{0})}^{2}}{\sum {(d_{1} + d_{0})}^{2}}}$ where d0 - specific weight of the first object's structural element; d1- the similar element's specific weight of the second object's structure.	Elkhina (2014)
The Coefficient of Relative StructuralS	$σ = \sqrt{\frac{L}{2} * \sum {(d_{1} - d_{0})}^{2}}$ where L - the number of dominant groups; d0- specific weight of the first object's structural element; d1- the similar element's specific weight of the second object's structure.	Kazinets (1981)
National Component or National Effect	${N S}_{i r}^{t} = E_{i r}^{t - 1} * \frac{E_{N}^{t}}{E_{N}^{t - 1}}$ where Er - the part of a regional indicator's growth; EN - the growth of a national indicator.	Herzog & Olsen (1977)
The Effect of Industry Structure	${M S}_{i r}^{t} = E_{i r}^{t - 1} * (\frac{E_{i N}^{t}}{E_{i N}^{t - 1}} - \frac{E_{N}^{t}}{E_{N}^{t - 1}})$ where Er - the part of a regional indicator's growth; EN - the growth of a national indicator.	Esteban (2000)
