摘要:An interregional model which minimizes production and transportation costs for broilers was developed and tested. Ten production and 22 consumption regions were defined. The results indicate that current flow patterns are relatively efficient given the existing production capacities. As demand increases the increased production will tend to be in the Southwest (Texas) and to a lesser extent in the Southeast (North Carolina). Shadow prices indicate that in the longer run production in the Northeast will continue to decline in relative terms and perhaps in absolute terms.
