到1970年,在不足10个发展中国家中已建立了约20个出口加工区;而到了1986年,在50多个发展中国家中就有175个出口加工区。在此期间,出口加工区的就业人数从5万人增至130万人,而其出口估值则从1.5亿美元增至100亿美元。出口加工区在地理上的迅速扩展反映了在全球经济和北南关系中发生了重大的政策性变化。 By 1970, some 20 export processing zones had been established in less than 10 developing countries; by 1986 there were 175 export processing zones in over 50 developing countries. During this period, employment in the EPZ increased from 50,000 to 1.3 million while its export valuation rose from 150 million U.S. dollars to 10 billion U.S. dollars. The rapid geographical expansion of EPZs reflects the significant policy changes that have taken place in the global economy and in North-South relations.
