独生子女家庭结构演变与养老方案选择研究①——以安徽省为例

独生子女家庭关系简单、脆弱,具有很强的风险性,为此引起学界和政府高度关注。文章利用2010年全国第六次人口普查数据资料,利用生命表方法构建独生子女家庭生命表．并推算丧子家庭、丧偶家庭、单人家庭等各类家庭结构演变趋势。得出：独生子女家庭中,丧子家庭在子女60岁时达到高峰,比例达到3．1％,其中丧子的父母单人家庭比例达到高峰值2．6％,丧子的父母空巢家庭在独生子女50岁达到高峰1．1％：独生子女单亲家庭（丧父或丧母）在独生子女55岁时达到峰值50％。不同的独生子女家庭,有着不同的养老需求,政府应该根据不同的家庭属性设置多样化的养老支持方案。     

Child Benefit Portfolios Across OECD Countries

Current research on the cross-national pattern of investment in child benefits mostly adopts the total resources approach and the model family method. The total resources approach conducts a broad comparison of the aggregate expenditure of different types of child benefit across countries. The model family method adds sophistication by comparing the values of child benefit packages of different countries, which combines different levels of spending in each type of child benefit, based on different family types with certain assumed characteristics. To complement the existing approaches, this study uses cluster analysis to classify countries into groups of similar investment strategies by simultaneously counting the different types and levels of child benefits of all countries. The findings show that four types of child benefit investment portfolio, namely Active, Moderate, Conservative, and Minimal, can be identified across OECD countries. While some studies have focused on the effects of individual types of child benefit on child outcomes, little is known about the effects of child benefits as a whole. The pattern of child benefits as investment portfolios could serve as a basis facilitating further investigation into its relationship with child outcomes. Preliminary findings indicate that child poverty, health, and satisfaction with school life differ significantly across investment portfolios, especially Active Investment outperforms Minimal Investment consistently.     

中国独生子女家庭与二孩家庭生育模式百年模拟与选择

不少人对中国的独生子女政策可能造成家庭负担过重忧心忡忡。通过独生子女家庭和“二孩加间隔”家庭未来百年发展变化模拟评价后认为：如果生育模式选择得当,独生子女家庭“四、二、二” 负担结构有可能基本避免,未来独生子女家庭的负担,也不会比历史上经历过的较重的负担更重。生育模式选择不当,生二个孩子,并不能保证比生一个孩子负担轻。从百年人口对资源环境和杜会经济发展的压力看,“二孩加间隔” 的政策无论如何组合和选择,所形成的人口压力都要显著大于独生子女政策,而独生子女家庭的生育模式如果选择得当,它的家庭负担不见得比生育模式选择不当的二孩家庭重多少。因此,政府应坚持稳定现行生育政策,坚持提倡一对夫妇只生一个孩子;同时应按最优生育模式,对生育年龄和间隔进行适当的调整。     

中国失独妇女总量、结构及变动趋势计算机仿真研究

在回顾以往对独生子女死亡和失独家庭研究的基础上，文章从基本概念、分析方法和关键研究问题等方面指出以往研究中存在的问题，提出终身失独概率估计方法和失独育龄妇女再生育可能性等，指出用独生子女死亡概念近似失独妇女，其结果有可能大大高估时期失独妇女的总量。由于受计划生育政策影响，中国育龄妇女二孩生育水平和生育模式发生巨大变化，将失独育龄妇女再生育看做是1－＞2递进生育也有可能高估失独妇女的总量。通过人口普查、抽样调查数据和计算机微观人口系统仿真分析技术，估计目前35岁及以上失独妇女数量在140万左右，2050年前中国时期失独妇女总量超过600万的可能性不大，失独家庭达到或超过1000万的可能性也不大。     

Federal financing of child care: Alternative approaches and economic implications

This paper surveys alternative approaches to financing child care at the federal level and discusses their economic implications with respect to female labor force participation, fertility, child care demand and supply, and poverty. The current system of federal support for child care is seen to consist of a series of overlapping programs that tend to create inefficiencies and inequities in the distribution of child care benefits. Four basic principles of an ideal child care system are outlined, and a general two-tiered system of support is proposed that would satisfy these four principles. The two-tiered system is centered on a refundable tax credit considerably more progressive than the current child care tax credit. A simulation analysis indicates that the proposed refundable tax credit would not cost much more than many of the more popular child care bills currently being debated in Congress.     

中国孩子质量与数量的替代关系现状分析——基于分位数回归方法

文章利用"中国健康与营养调查"2009年度的相关数据,采用分位数回归方法对我国孩子质量与数量间的替代关系进行分析研究,证实在生育政策与社会经济发展双重效力下的我国家庭孩子数量的减少,同时使孩子的质量得以提高。此外,孩子的性别、父母的学历、家庭所处地理位置、家庭长期福利水平以及家中孩子的性别组成也对孩子的质量有显著影响。     

An alternative sampling strategy for obtaining child health data in a reproductive health survey

Retrospective demographic surveys typically collect substantial information about child health. This information is often collected for all children born during a specified period. For women with several young children, the interview can become quite long. To shorten the interview, some surveys have asked child health questions only for the last child born. However, data on the last birth may be biased because last children have a younger age distribution and have longer subsequent birth intervals than does the average child. In this paper, we propose an alternative approach to collecting child health data - that child health questions be asked only for a child chosen randomly from among the respondent's children younger than age five. This alternative has the advantage of keeping the interview shorter but does not lead to biased information.Abbreviations DHS Demographic and Health Surveys     

Bidirectional longitudinal associations of parent and child health following the BP Deepwater Horizon oil spill

This study (1) assessed whether parent health mediated associations between exposures to the 2010 BP Deepwater Horizon oil spill (BP-DHOS) and child health, and whether child health mediated associations between BP-DHOS exposures and parent health; and (2) assessed bidirectional longitudinal associations between parent health and child health following the BP-DHOS. The study used three waves of panel data (2014, 2016, and 2018) from South Louisiana communities highly impacted by the BP-DHOS. Parents with children (aged 4–18 at the time of the interview) were interviewed based on a probability sample of households. Focal measures included economic and physical BP-DHOS exposures, self-reported parent health, and parent-reported child health. Health measures were gathered at three time points. The analyses included mediation analysis and estimating and comparing effect sizes of longitudinal cross-lagged effects between parent health and child health. Results showed that parent health partly mediated associations between BP-DHOS exposures and child health, and that child health partly mediated associations between BP-DHOS exposures and parent health. Paths from prior waves of parent health to subsequent waves of child health were positive and statistically significant as were paths from prior waves of child health to subsequent waves of parent health. The differences in size of the child-to-parent health effects and the parent-to-child health effects were not statistically significant. This study’s results extend evidence for the post-disaster effect of parent health on child health and the effects of child health on parent health. These findings support the contention that harm to the health of one’s family member following disasters operates as a form of resource loss deleterious to one’s health.

     

Social Structure and Child Poverty

Child poverty, as a critical indicator of the QOL, is intricately related to the social structure of the community. This hypothesis is explored for the 159 counties of Georgia for the year 2000. The influence of demographic, economic, family and health factors upon child poverty are explored through models of total, black and white child poverty. Factor analyses of factors uncovered by the models identify the social-structural features of counties in relation to child poverty. Counties considered “Deprived/rural” harbor child poverty, while counties described as “Business/money” and “Progressive/urban” bear a negative relationship to child poverty. Positively associated with child poverty are residential stability, unemployment, low educational achievement, youth and age dependency, single-parent female household heads with children, grandparent child care, and health disability of child, elders and of working-age persons. Structural factors militating against child poverty are persons with greater education, higher population density, out migration, larger married population, higher retail sales, larger middle class families, higher weekly wages, and other structural features of the county.     

Divorce and parity progression following the death of a child: A register-based study from Finland

Most studies that have examined whether a child’s death influences parental relationship stability have used small-scale data sets and their results are inconclusive. A likely reason is that child loss affects not only the risk of parental separation, but also the risk of having another child. Hence parity progression and separation must be treated as two competing events in relation to child loss. The analysis in this paper used Finnish register data from 1971 to 2003, covering over 100,000 married couples whose durations of both first marriage and parenthood could be observed. We ran parity-specific Cox regressions in which process time started from the birth of each additional child. All marriages included women of childbearing age, none of whom had experienced any child death on entering the analysis. We find that child loss only modestly influences the divorce risk, whereas its effect on the risk of parity progression is considerable.     

用孩次递进比模拟“全面二孩”政策调整初期的生育行为--以湖北省为例

以2014年湖北省卫生和计划生育委员会提供的包括“单独”、“双独”方面的数据为基础,描述了生育政策调整下被压抑的生育潜能释放的规律性和用孩次递进比的方法预测“全面二孩”政策调整初期的生育行为,与意愿分析方法相互比照,丰富了当下生育政策下生育行为预测研究。从分析结果可以看出,假定2016年“全面二孩”生育政策调整,湖北省第一年内会新增二孩出生量52621人,占湖北省2014年总出生量的7?41％;三年内最低会新增139262人的二孩生育量。城乡对比发现,农村新增二孩生育占到将近六成,且由抢生而导致的堆积主要集中在农村,40岁后的高龄抢生情况不严重。     

Time use in child care and housework and the total cost of children

The use of time for child care and housework among Swedish families is investigated. We allow the effect of children on child care and housework to vary by age of the child and also by whether the child is cared for outside the home or not. Our estimates allow us to compute the total cost of children in the form of the cost of time, and the cost of goods, services and housing.The result shows that time used for child care decreases sharply with the age of the child but this is not the case for time used for other housework. Considerable economies of scale is found to prevail for time used for child care. Child care outside the home reduces time use for other housework but the effect on time used for child care is quite small. For the average family time use cost make up more than half of total child cost. Our estimates indicate that decreased time use cost for children caused by care outside the home are not very different from a typical parental fee for public day care.This research was supported by a grant from the Swedish Council of Social Research (SFR).

Some aspects of the relationship between the levels of infant mortality and fertility in the ESCAP region

The death of a child within the first year of life is a crucial factor in fertility decisions in a developing country. The infant mortality rate gives a close, inverse indication of the socioeconomic conditions of a country. This paper presents studies by Brass, Rutherford, Chowdhury, Khan and Chen, Agrawal, Iskander and Jones, in summary/abstract form. It concludes that the probabilities of survival are poorer for births of older women and/or higher parities. Early child deaths may increase the total period of exposure to the risk of conception. A lower infant and child mortality norm calls for fewer births to meet the needs for survivors. Child replacement motivational response seems to be strongest with the birth immediately following a death event. Agrawal analyzed the interval between successive births of 1107 women of Patna, Pakistan, according to the age of mother and sex and fate of the previous child. He observed that if a child died shortly after its birth, often a new pregnancy began within a short interval. The interval between 2 consecutive live births when the previous child was male and alive was greater than when the previous child was female and alive. The interval between 2 births was reduced if the child died in infancy and specially if this was a male child.     

Analysis of child labour in Peru and Pakistan: A comparative study

This paper analyses child labour participation and its key determinants using data sets from Peru and Pakistan. The results include tests of the ‘Luxury’ and ‘Substitution’ hypotheses that play key roles in recent studies on child labour and child schooling. The results reject both hypotheses in the context of child labour in Pakistan and suggest that income and related variables do not have the expected negative effect on children's work input. Rising wages of adult female labour in Pakistan, and falling adult male wage in Peru lead to increased participation of children in the labour market. The results on the combined country data formally establish the presence of strong individual country effects in the estimated regressions. For example, ceteris paribus, a Peruvian child is more likely to experience schooling than a Pakistani child. However, both countries agree on the positive role that adult female education and infrastructure investment in basic amenities can play in discouraging child labour and encouraging child schooling.

The determinants of paternity establishment and child support award rates among unmarried women

This paper examines the relationships between several child support policies, paternity establishment, and child support award rates among never-married women. We use several state policies and practices in place throughout the 1980s to examine their effectiveness at increasing paternity establishment rates and at increasing the proportion of unmarried women who have child support awards. We also examine the direct relationship between paternity establishment rates and child support award rates. We estimate these relationships using a variety of specifications, using cross-state variation in child support enforcement to identify the effects of policies. To date, child support remains largely the province of state family law, and, although policies have changed dramatically in response to two decades of federal mandates, state laws and practices still vary.     

儿童照料与二孩生育意愿 ——来自上海的证据

本文围绕一项针对上海市育龄女性的生育意愿调查,分别使用二分和有序Logit方法分析儿童照顾对上海市育龄女性的二孩生育意愿的影响。研究发现当育龄女性能够从家庭内和社会中获得更多孩子照料的时间支持时,她们有更高的二孩生育意愿,也会伴有更明确的二孩生育规划;双独家庭能够从父辈获得更多的经济、时间上的帮助,因此他们要比单独家庭和双非家庭更愿意再生一个孩子;居住于上海市城区的女性从某种程度上更易获得孩子的照料资源,有更多的优质教育资源可供选择,因此她们的二孩生育意愿高于居住于郊区的女性。此外,本文通过是否采用了避孕措施对二孩生育的意愿程度做了进一步区分,结果发现当第一个孩子主要是由孩子父母承担照料工作的时候,女性存在二孩生育意愿的程度是最低的,祖辈照料对二孩生育意愿程度的积极影响也明显低于社会性照料,此现象在上海市户籍的女性中体现尤为明显。最后为纠正自选择偏差问题,本文使用倾向值匹配方法(PSM)进一步验证了与首孩性别相比,首孩的抚养成本与接受照料情况显然对二孩生育意愿的影响程度更大。因此,本文认为加大公共托育服务的供给、为育龄女性提供高质量的0-3岁婴幼儿社会照料支持是提高二孩生育意愿的最有效政策。     

Family planning's benefits include improved child health and nutrition: new data from Bangladesh

2 recent studies from the Matlab in Bangladesh confirm that family planning promotes child survival. The 1st study is a longitudinal analysis of 3370 births in 1985 to women living in 70 villages who were served by the International Centre for Diarrhoeal Disease Research, Bangladesh's Matlab Family Planning and Health Services Project. The 2nd is a study of 12-26 month old children and 24-36 month old children, all of whom were born in the same 70 villages between July 1985 and June 1986. The 1st study demonstrates that family planning improves child survival by lengthening the birth interval. In fact, if women delay a subsequent birth by about 2 years, child survival improves at all ages up to 5 years. Longer birth intervals result in a reduction of very high order births. The same study also reveals that family planning improves child survival indirectly by granting mothers access to integrated maternal and child health services. The 2nd study indicates that a child is 3 times more likely to suffer malnutrition, even at age 3, than a child whose mother gives birth again at an interval greater than 24 months. Specifically, the mother removes the index child from the breast prematurely, thereby adversely affecting the index child's nutrition. The birth interval prior to the index child does not adversely affect the index child's nutritional status, however. The 2nd study's result suggest that birth spacing, as promoted by family planning programs, improves child health and nutrition. The findings from these studies show the importance of continued investments in family planning programs in developing countries.

The Influence of Local Price and Availability on Parents’ Choice of Child Care

The striking variation in patterns of child care usage across states reflects differences in family characteristics, but may also reflect exogenous differences in local child care markets. Type of care selected will be influenced by the availability, cost, and accessibility of supply in the child care market as well as by family and child characteristics and cultural preferences. This study contributes to the growing literature on parental demand for child care by using a recent detailed data set from the state of Minnesota. We link household-level data on child care usage and family characteristics with county-level data on average provider rates and availability by type of care in order to estimate multinomial logit models analyzing the family, child, and market characteristics that predict type of care. Our analysis shows that using a relative or friend to care for a child is largely determined by availability, and choice of family care providers is most responsive to price for employed mothers. The types of care chosen by mothers who are not in the paid labor force differ substantially from the choices of employed mothers, and their use of center care is influenced by the prices of both center and family providers. Attitudes towards relative care are also shown to influence type of care chosen.
