Economic region of production Economic region of production In economics, the economic region of production is an offshoot of the theory of production function with two variables. It is a cost-oriented theory which defines the region in which the optimal factor combination will lie. It serves as a map of the region of optimal production. Production lines Q1 and Q2 are the isoquants, depicting the technically efficient factor combinations at different levels of production. The ridge lines A and B demarcate the technically efficient region of production. Above the line OA and below the line OB slope of the isoquants is positive which means
