摘要：The beef supply chain has been traditionally
described as a complex intertwining of multiple
vertically sequenced segments characterized by
intense rivalry and adversarial positions between
supply-chain participants. However, this description
of the beef supply chain is beginning to change as
a result of the agroindustrialization process. First,
the beef supply chain has witnessed concentration in
all segments over the last few decades. The number
of cow-calf producers, feedlots, and beef slaughter
plants has suffered significant decline as the industry
adjusts to slow growth in domestic beef consumption.
In addition, concentration in food retailing and
changes in consumer preferences and buying habits
are affecting business practices, resulting in tighter
linkages and coordination between segments of the
beef supply chain.
