Changes in Global Trade Flows
Prior to the 1970s, global trade flows were dominated by three major
poles, North America, Western Europe and Pacific Asia (also known as
the triad). A dichotomy was
observed between developed and developing economies as raw materials
were flowing north and finished goods were flowing south. This situation
can mainly been explained by differences in levels of development as
well as by unequal trade relations set during the colonial era.
From the 1970s, this situation changed as industrial
development took place in many developing economies in Latin America
(Mexico), Southeast Asia (Malaysia, Thailand, Indonesia) and East Asia
(China, South Korea, Taiwan). Many industrial processes which initially
took place in developed economies, were relocated in new locations offering
lower production costs, namely because of cheaper labor. Such a
structural shift if well illustrated by the variation in the
share of development economies in seaborne trade, which used to
be highly imbalanced with much more cargo being loaded than
unloaded. Economic development resulted in a growing share of
developing economies as a destination for cargo. Consequently,
global trade is now characterized by significant flows of cargoes
(raw materials, intermediate and finished goods)
from developed to developing economies.
