山东省"十五"期间规模工业行业调查与比较分析

通过山东与广东、浙江、江苏及全国的“十一五”期间规模工业比较分析,认为:山东省规模工业综合实力明显增强,重工业比重明显上升,行业成长性全国第一,规模工业增加值占GDP比重居四省第一,规模工业利润率水平高于全国和其他省份水平,但是,山东省规模工业行业集中度低于其他三省,规模工业中装备制造业总体比重较弱,产业层次相对偏低,制造业工资水平低于其他省份和全国平均水平,城市化进程严重落后于工业化进程。最后,提出未来山东规模工业的发展方向是加快发展装备制造业,发展高新技术产业,大力发展循环工业和生态工业园区,以加快推进城市化进程带动山东工业化进一步发展。     

Differentials in urban-rural fertility in the countries of the ESCAP region

Fertility differentials between rural and urban populations are investigated using World Fertility Survey data for Bangladesh, Fiji, Indonesia, Malaysia, Nepal, Pakistan, the Philippines, the Republic of Korea, Sri Lanka, and Thailand. "The fertility measure used in this analysis is the number of children ever born to a woman. An attempt is made first to establish the differential in fertility levels between urban and rural areas after necessary control of the demographic factors..., and then the possible explanation of the differential is sought in terms of socio-economic variables such as education of the respondent, and occupation, work pattern, work status and place of work of the respondent as well as that of the husband." Data concerning the fertility differentials and the associated explanatory variables are presented in tables and charts. "The results tend to show that the countries of Asia are undergoing similar patterns of fertility transition as was experienced in the advanced countries. Perhaps one can graduate the countries in the transition scale as follows: Bangladesh, Indonesia, Nepal, Pakistan and Malaysia are in the initial stage; Fiji, the Philippines, the Republic of Korea, Sri Lanka and Thailand are in the middle stage of transition."
