Leontief’s Fundamental Equations (基本方程式):
Quantity(数量):
x = (1 + g ) Ax + d ,
g: 均斉成長率
d: 最終需要ベクトル、 d = (d1 , d 2 )'
 x = a ⋅ x + a ⋅ x + d1
g=0 の場合、  1 11 1 12 2
 x2 = a 21 ⋅ x1 + a22 ⋅ x2 + d 2
Price(価格):
p = (1 + r ) pA + l ,
r: 均衡利潤率
 p = a ⋅ p + a 21 ⋅ p2 + l 1
r=0 の場合、  1 11 1
 p 2 = a12 ⋅ p1 + a22 ⋅ p 2 + d 2
