In China, for example, the relaxation of migration controls in the 1980’s and the opening of the economy led to the spectacular growth of the country’s eastern cities. More than 50% of Chinese live in urban areas today, up from 25% in 1990, and the proportion is expected to reach 70% by 2035.
比如，在中国，20世纪80年代对人口迁移管制的放松以及改革开放使其东部城市迎来了壮观的增长。如今，超过一半的中国人居住在城市，而1990年只有四分之一，到2035年，城市人口比例预计将达七成。
