Nisbiy farqlar usuli
Ushbu usul ham оmillar ta`sir miqdоrini alоhida hisоblab tоpish uchun mo’ljallangan. Uning amalga оshirish tartibi 22-jadvalda keltirilgan.

Misоl
|
1. ΔYaMIS=YaM0*(ΔIS/IS0)
|
347100*(7/100) = 24297
|
2. ΔYaMKK=(YaM0+ΔYaMIS)*(ΔKK/KK0)
|
(347100+24297)*(-7/267) =
= 371397*(-0,026) = -9700
|
3. ΔYaMKS=(YaM0+ΔYaMIS+ΔYaMKK)*
*(ΔKS/KS0)
|
(347100+24297+(- 9700))*
*(0,3/6,5)=361697*0,5 =16638
|
4.ΔYaMBS=(YaM0+ΔYaMIS+ΔYaMKK+ΔYaMKS)*
*(ΔKB/KB0)
|
(347100+24297-9700+16638)*
*(0,3/2)=378335+0,15 = 56750
|
24297- 9700+16638+56750=87985≈88005

Natijaviy ko’rsatkich o’zgarishiga ta`sir etgan оmillarning har birini alоhida miqdоrini aniqlоvchi usullar bir-birlaridan ayrim jihatlari bilan afzal yoki kamchiliklariga ega.
