人口迁移对90年代珠江三角洲人口发展的影响

90年代大量人口向珠江三角洲的迁移集聚，不仅使总人口快速增长、人间分布发生变化、城市化水平显著提高，而且降低了人口性别比、延缓了人口老龄化进程、及受高等教育程度人口比重的提高。虽然人口增速全国最高，但以珠江三角洲为核心的广东省，国内生产总值年均增长速度却低于东、中部部分省市，说明劳动密集型产业的迅速发展是迁移人口迅速增长的主要原因。大量人口迁入，增加了对环境的压力和产业结构调整的难度。建议通过产业政策和区域政策引导、加快城乡劳动市场一体化的步伐、加强对企业经营和劳动用工的调控、健全社会保障体系等，促进提升产业结构和技术结构，缩小区域差异。

AFFECTS OF MIGRATION TO POPULATION DEVELOPMENT IN THE PEARL RIVER DELTA IN 1990'

Large amount of population, especially temporary population migrate in The Pearl River Delta in 1990'. Not only pushed quickly population growth and urbanization increase, changed clearly population distribution, but also decreased population sex ratio, delayed the speed of population aging and the increase rate of population education level with university and college. Though the increase rate of total population is the highest in the whole country, the average increase rate of GDP in Guangdong, which is centraled with The Pearl River delta, is lower than that of some other provinces or cities in the east and central parts of China. This means that the quick development of labor accumulated industry is the main reason of the fast increase of migrants. Huge amount of migrants has not only enlarged the pressure to social and nature environment, also has made the adjustment of industry structure more difficult. This paper suggests that through enhancing the guide of industrial policy and regional policy, pushing the speed of urban and rural labour market merge together, strenghtioning the adjustment and control to the engagement and employment of enterprices, and perfecting social secure system, and as a result to proceed the arise of industrial structure and technical structure, and to narrow regional disparity.
