论北京“城中村”改造——兼述流动人口聚居区合作治理

2009年以来北京开始进行大规模的城中村改造。这场由政府主导的乡村社会变革,对城乡结合部流动人口聚居区产生了重要影响。本文在概括北京城中村改造模式的基础上,对城中村改造的作用给予了积极评价,同时指出城中村改造周边地区可能面临更深的发展困境,应通过合作治理寻求解决城乡结合部流动人口聚居区社会问题的治理之道。目前北京已经具备了实现流动人口聚居区合作治理的基本条件,可以在市区政府是主导、乡村组织是枢纽、社区成员是核心、社会团体和社会单位(企业)是支撑、专业NGO是助推器的合作治理框架下,以生活设施改造和社会管理体制创新为突破口,统筹兼顾尚待城市化地区的协调发展。     

流动人口居留意愿内部分化研究——以温州市为例

利用2009年在温州市进行的人口结构变化专项调查资料,将流动人口作为一个非均质的整体进行研究,采用数据交叉分析方法,分析了流动人口内部在居留意愿上的分化,并对流动人口居留意愿的影响因素进行了多分类的logistic回归分析。结果表明,大部分流动人口尚未有在流入地长期居留的打算,但滞留趋势明显;打算最终返乡的流动人口比例较高,非永久居留是一种常态化的现象;流动人口内部在居留意愿上存在明显分化。结合以上分析,讨论了流动人口居留意愿分化对制定流动人口政策和选择城市化战略等方面的思考。     

中国老年人口健康预期寿命延长还是缩短？——基于Sullivan方法的实证研究

随着老年人口数量在总人口中不断增长,中国人口的总体健康水平。特别是老年人的健康预期寿命将会发生新的变化。中国老年人口的健康预期寿命是在增长还是在缩短？老年人口的健康预期寿命在总预期寿命中的比例是在增大还是在缩小？搞清楚这个问题对于我们合理地制定老龄政策至关重要。本文尝试应用国际上最为流行的Sullivan方法回答上述问题。     

黑河流域人口承载力预测分析

人口承载力的研究对象是由若干个内部关系错综复杂、相互之间联系紧密的子系统所组成的“自然-经济-社会”复合巨系统,本文运用系统动力学建立复合模型仿真模拟预测黑河流域人口承载力状况．并建立黑河流域人口承载力的预警指标体系。复合模型预测数据显示,黑河流域人口承载力呈超载状态．而预警目标值Z=0．979〈1,说明该区没有实现持续发展,乃“磊、乙三个指标小于1,说明黑河流域生态环境和固定资产投资占比是影响黑河流域发展的主要因素。     

上海城市人口总量控制与结构优化研究

上海的人口总量和结构一直与其独特的工业化、城镇化进程密不可分。工业化带动人口发展,人口发展推动城市发展。改革开放以来,上海正处于第四波工业化时期,人口增长较快。在人口结构上,户籍人口老龄化,而外来人口具有就近流动、城城流动、定居化特点,且教育水平逐年提高。从承载力上看,上海人口总量合理,但人口分布的不合理影响了人口结构的发展、城市社会的融合,带来了核心区人口过密、产城融合不畅的问题,以及偏好"人脑"、排斥"人手"的问题。面对人口老龄化和可能的人口逆流,上海应稳定人口总量,建设整体推进的多中心发展人口分布格局,完善户籍制度改革,破解"新二元结构",推动社会保障和公共服务均等化,同时结合政府改革,完善相关配套改革措施。     

Imprisonment and (inequality in) population health

This article extends research on the consequences of mass imprisonment and the factors shaping population health and health inequalities by considering the associations between imprisonment and population health—measured as life expectancy at birth and the infant mortality rate—and black-white differences in population health using state-level panel data from the United States (N = 669), 1980-2004. Results show that imprisonment is significantly associated with poorer population health, though associations between imprisonment and infant mortality and female life expectancy are somewhat more consistently statistically significant than are associations with male life expectancy, and associations are more pronounced and statistically significant for blacks than they are for whites. Results also show, however, that increases in imprisonment are associated with decreases in the mortality rates of young black men. Thus, though imprisonment tends to be associated with higher mortality risk and greater black-white differences in mortality, it may, in the short-run, have some paradoxical mortality benefits for young black men.     

提高深圳出生人口素质的理论与思考

台湾出生性别比的状况分析和对策研究

通过梳理有关台湾的人口资料,首先发现台湾出生性别比的发展呈现出总体偏高的趋势,其产生的原因是多种因素共同作用的结果。其次对台湾治理出生性别比偏高的直接和间接措施进行分析,直接措施是加大对非法性别鉴定的处罚,间接措施是消除不利文化的影响,营造促进妇女发展的社会环境。这些措施最终达到了＂标本兼治＂的目的。最后借鉴台湾治理出生性别比问题的经验和教训,为治理中国出生性别比偏高的问题提供相关对策。     

Determinants of fertility levels and change among developed countries: 1958–1978

This article provides a multivariate cross-national test of the hypothesis that national population/family planning policies have effected levels, and changes in fertility in developed nations over the past two decades. Variation is assessed in the total fertility rates (TFR) in 1978, and in the change in these rates between 1958 and 1978, among thirty developed countries. Measures include socioeconomic development, divorce, percent in consensual unions, female labor force participation, abortion policy, and level of contraceptive use by married couples and, government population/family planning policy. Seventy percent of the variation in 1978 TFR is related to the percent contracepting, female labor force, and the population/family planning policy measures. These are the only measures with significant direct effects. A longitudinal analysis of 1958 to 1978 change in TFRs is also conducted. This model increases R² to 75%, and the three independent variables remain significant. Implications of these findings for policy makers interested in increasing or decreasing fertility rates are noted.     

Designing two factor experiments for selecting interactions

This paper considers the problem of devising a single stage procedure for selecting the treatment combination associated with the largest interaction in a two-factor rfx× c experiment having independent normally distributed observations with common known variance. The intuitive procedure based on the best linear unbiased estimators of the population interactions is employed. Initially an indifference zone formulation is used; the problem of determining the least favorable configuration is reduced to a nonlinear programming problem with log concave objective function and a convex polytope as feasible region. A solution technique is introduced in the context of an illustrative example. The problem is also considered using a preferred population formulation; this approach requires a strengthened version of the indifference zone probability requirement. It is shown that the same sample size guarantees this requirement as does the earlier one.
