预期寿命增长、年龄结构改变与我国国民储蓄率

人口年龄结构趋于老龄化和人均预期寿命逐步增长是目前我国人口发展的两个典型特征,而年龄阶段不同,个人的收入、消费与储蓄行为也不同。基于生命周期理论,在选定相关分析指标的基础上,文章使用我国省际平衡面板数据,实证分析了我国人口预期寿命增长和年龄结构改变对国民储蓄率的影响。分析结论表明,人口预期寿命增长提高了我国国民储蓄率;不考虑时间效应时,幼年人口负担比提高会减少国民储蓄率,而老年人口负担比提高会增加国民储蓄率;在考虑时间效应时,幼年人口负担比提高会增加国民储蓄率,而老年人口负担比提高会减少国民储蓄率。对此,文章给出了合理的解释。通过使用多种估计方法,我们发现所得到的结论是基本稳健的。     

中国城镇居民家庭储蓄水平队列效应分析

利用中国家庭收入调查（ CHIP）数据对城镇居民家庭的储蓄率进行了队列效应的实证研究。分析结果表明,属于不同队列的城镇家庭在储蓄水平上都呈现出相似的“U”型年龄分布,即中年家庭（40－50岁）储蓄率低,年轻家庭（20－40岁）和退休家庭储蓄率较高,这一现象与其他国家的实证研究结果有显著不同。本文认为,中国城镇居民储蓄率的“U”型年龄分布主要是由人口与经济的高速增长带来的：人口高速增长带来的队列规模效应使得面对更大竞争压力的年轻人口储蓄率较高,而经济水平持续增长带来的消费水平增长预期使得接近退休家庭储蓄水平重新上升。     

人口抚养比对国民储蓄的长期动态影响研究北大核心CSSCI

中国的高储蓄现象举世瞩目。1978年以来,在中国经济快速增长的过程中,国民储蓄水平不断上升,与此同时人口抚养比发生了巨大的变化,因此,探讨人口抚养比变化与国民储蓄之间的联系是分析中国高国民储蓄原因的重要方面。本文采用1978～2008年时间序列数据,利用VECM模型,研究人口抚养比变化与国民储蓄的长期动态关系,发现:1978年以来,总抚养比下降引起了国民储蓄上升,其中,少儿抚养比对国民储蓄具有显著的负向影响,老年抚养比对国民储蓄影响不显著。从影响时间看,总抚养比变化对国民储蓄影响时间约为20年,其中主要影响发生在前6年。随着总抚养比的逆转,国民储蓄将逐渐下降,高储蓄只是中国经济发展特定时期的现象。     

分段预期寿命对国民储蓄率的影响效应

文章在生命周期理论基础上,引入分段预期寿命,利用178个国家和地区的1981~2010年跨国面板数据,验证工作期与老年期预期寿命对国民储蓄率的影响。结果发现,老年期预期寿命对国民储蓄率有正向影响,而工作期预期寿命对国民储蓄率有负向影响。实证结果显示,样本期内预期寿命的延长,使中国国民储蓄率增加约6.53个百分点,其中老年期预期寿命的延长,使国民储蓄率增加约7.46个百分点;工作期预期寿命的延长,使国民储蓄率降低约0.93个百分点。随着中国预期寿命延长模式由工作期与老年期预期寿命共同主导向老年期预期寿命主导的转变,预期寿命延长对中国国民储蓄率的影响效应可能会进一步增强。     

中国人口结构变动与制造业出口结构优化

本文首先从理论上分析了人口结构变动对出口比较优势的影响，然后利用中国2001—2010年28个制造业和人口结构数据，采用交叉项方法实证研究了人口结构少子化和老龄化变动趋势对出口结构优化的影响。结果发现少子化使未来劳动力供给和消费减少、储蓄和投资增加；老龄化使劳动效率下降，居民预防性储蓄增加。人口结构变动使资本素变得相对充裕，劳动素相对稀缺，促使出口结构实现优化升级，由劳动密集型商品出口为主向资本密集型商品转移。     

储蓄投资行为及外部均衡中的人口结构效应——来自亚洲的经验证据

文章运用动态广义矩估计方法,分析亚洲人口年龄结构对储蓄率、投资率及经常账户的效应。结果发现:(1)人口结构对储蓄的效应存在,老年人口抚养比对储蓄率有显著负向影响,符合生命周期假说;(2)少儿抚养比与储蓄率无显著相关,少儿人口抚养质量与数量间存在替代效应;(3)老年人口抚养比效应对于外部均衡非常显著。老年化经济体对于经常账户逆差存在依赖,经常账户可以视为亚洲人口红利期高储蓄的国际"缓存池"和"中转地"。亚洲的经济增长、高储蓄与高顺差呈现梯队性的趋势,且与人口结构的变迁一致。这些发现可以从人口结构角度解释亚洲的高储蓄和高经常账户顺差及国际资本流动。所以,世界经济体应避免同周期的老年化,以保证经济的梯队发展和资源跨代跨国转移;同时,对于减少少儿人口来压缩社会负担的政策效果不能预期过高。     

遗产动机对中国老年家庭储蓄率的影响

中国人口老龄化问题日益凸显,老年家庭储蓄率居高不下,标准生命周期假说理论已无法解释。基于中国家庭金融调查数据,从遗产动机视角分析老年家庭高储蓄率现象。研究结果表明,中国老年家庭遗产动机显著提升家庭储蓄率,遗产动机使得老年家庭储蓄率水平显著提高5%—10%左右。进一步研究发现,相比较于城市家庭,遗产动机对农村家庭储蓄影响显著;相对于高等财富家庭而言,遗产动机显著促进中低财富家庭储蓄率水平,说明“未富先老”使得老年家庭有更强的遗产动机进行储蓄;对于家庭不同生活状况的子女,遗产动机显著提升子女体制外工作和子女教育水平低的老年家庭储蓄率,表明中国老年家庭利他主义的遗产动机较强。本文为理解中国老年家庭的高储蓄提供了新的视角,可以为政府相关部门制定政策提供参考。     

中国老年人储蓄对家庭消费的影响 ——基于CHARLS面板数据的分析

在我国快速老龄化和居民储蓄率居高不下的背景下,结合老年人储蓄偏好和消费特点,构建家庭消费计量分析模型,文章利用CHARLS2011、2013、2015年微观跟踪调查数据,采用工具变量—随机效应模型划分年龄层次和消费类别逐级估计,重点考察老年人储蓄对其家庭消费的影响。研究表明,老年人储蓄水平越高,对家庭消费的促进能力就越强;分城乡来看,农村老年人储蓄对家庭消费的贡献更大;按年龄组别来看,中、低龄老年人储蓄对家庭消费的影响显著,高龄老年人储蓄对家庭消费的影响不显著;按消费类别看,老年人储蓄偏重于家庭基本生活、教育文化、健康等刚性消费支出,城镇和农村老年人储蓄对不同消费类别影响的差异主要表现在日常支出、医疗保健和耐用消费品等方面。此外,研究还发现,老年人拥有房产对家庭消费具有非常明显的提振作用,家庭收入和老年人借贷对家庭消费的贡献显著。     

收入、人口年龄结构和中国城乡居民储蓄

本文利用中国2002~2006年分省、分城乡数据,将人口年龄结构因素纳入绝对收入和恒久收入理论模型,对居民储蓄方程进行了实证研究。研究发现:老龄人口比例对城乡居民的储蓄有显著的负影响,这对于老龄化日益严峻的中国意味着将面临人口转变带来的额外的资本供给压力;城、乡居民的储蓄决定因素有明显的差别,这些差别反映了城乡收入差距、区域经济差距以及城乡居民对子女教育投入的差异。     

中国各地区人口年龄结构变动的消费效应分析

消费是影响一国经济增长的重要因素,对于影响消费的众多因素研究,大多基于收入分配不均和收入不确定性视角,而忽略了另外一个非常重要的因素,那就是人口年龄结构变化对消费的影响效应。上世纪70年代计划生育政策的推行和人口预期寿命的延长,加快了我国人口转变及老龄化发展的步伐,这一转变必将改变居民的储蓄消费行为,影响储蓄-消费模式和消费率。基于我国2002-2008年省级面板数据,本文研究了各地区人口转变对消费率的影响。研究表明,消费率与少儿抚养比、老年抚养比之间分别存在正相关关系与负相关关系。     

Regional differences in marital fertility in the Netherlands in the second half of the nineteenth century

Abstract In the Netherlands, as in other countries, substantial regional differences in the birth rate have always been the rule rather than the exception. Of course, differences in crude birth rates may be attributed to a number of possible reasons, not all of them of primary demographic interest. For instance, according to the census of 31st December 1899, the number of women per 1,000 men in the province of Drenthe was only 924; in the province of Zuidholland the corresponding number was 1,073. It is clear that, ceteris paribus, the crude birth rate in Zuidholland would be about 7% higher than in Drenthe at that time. In such a case, the difference could reflect differences in economic development or job opportunities, factors not devoid of demographic significance, but only indirectly so.     

Why the rise in adolescent fertility rates in the Dominican Republic in the 1990s?

Despite concern over high pregnancy rates and levels of risk for sexually transmittedinfections, adolescent fertility rates in the Dominican Republic have not changed substantially since the early 1980's, and actually increased during the early to mid 1990s. The present study was undertaken to assess the factors contributing to the recent rise in fertility among Dominican adolescents. The findings suggest that although contraceptive use among adolescents and young adults has increased, this has been more than offset by ominous trends on other determinants of fertility. Among these are declines in mean age at first sex and first marriage/union without a commensurate decline in mean age at first contraceptive use, and stubbornly high discontinuation rates for oral contraceptives andcondoms. There is also some evidence that rates of induced abortion among adolescents may have increased, without which adolescent fertility rates would have been even higher. Demand for children among Dominican adolescents remains strong, suggesting that efforts to reduce the current high prevalence of risky sexual behaviors need to influence social norms in order to be successful.     

乡-城转移人口的生育率水平问题

乡一城人口转移作为城市化过程,总体上有利于生育率下降或低生育水平的稳定。但是,由于乡一城转移人口的生育率水平具有既不同于城也有别于乡的差别特征,因此这种转移对城乡生育率的变化必然产生一定的差别效应。通常认为,乡一城转移人口的生育率水平介于城乡之间,即低于乡而高于城。但是,有关研究认为,我国乡一城迁移流动人口的生育率水平已经转变为低于城市。对此,很值得进一步深入探讨。本文首先分析我国城乡生育率的变化和区域差异,然后对乡一城转移人口的总和生育率进行尝试性的推算,最后聚焦讨论流动人口生育行为的流动性问题。

Social Reporting in the 1970s and in the 1990s

In this paper I give an account of the major welfare conceptsand social reporting concepts of the 1970s, 1980s and 1990s. Inconclusion I discuss possibilities and limits of social reporting today.Quality of life and qualitative growth were the welfare programs of the1970s. The next decade saw a trend to individualization, subjectivewell-being and plurality of life styles. In the last decade the qualityof society once more came into the forefront in concepts likesustainable development, human development and social capital. From thefar-reaching program of the social indicators movement socialreports are the most visible results in many countries whereas ambitiousplans like national goals accounting failed. In the 1980s we watched akind of dissolution by diffusion and in the 1990s a revival inseveral fields. Overall, the monitoring and enlightenment function stillis the most important contribution of social reporting but today on ahigher level of data, methods and international comparisons.     

Keeping the ball in the air: contact in long-distance friendships

As people continue to be more mobile, maintenance behaviors for long-distance friendships will continue to be a part of the relocation experience. In this qualitative study, 25 women age 45 and over, who had relocated a number of times, were asked to talk about how their friendships had transitioned to being long-distance relationships and what current maintenance behaviors entailed. Communication was a major theme involving electronic mail (e-mail), Christmas cards, telephone calls, and visits. Results from the current study suggest that maintaining the perception of the existence of a well-connected social support system could be accomplished with a single, annual contact. Further, the long-distance friendship biographies explored in this study provided characteristics of friendship maintenance behavior that could be grouped into three main categories forming a proposed typology of long-distance friendship maintenance.

The fall in household size and the rise of the primary individual in the United States

The long-term fall in household size in the United States is discussed within the framework of the aging of the population, continuing as the effects of fertility and mortality decline accumulate. Using distributions of households by size from U.S. census data 1790–1970 and a components of change analysis on primary individuals for 1950–1974, household changes are related to demographic change for the periods 1790–1900, 1900–1950, and 1950–1974. Fertility and mortality declines have unambiguous impact on household size until the increases in primary individuals begin. But these, too, have a theoretically interesting, if indirect relationship to population structure.     

Measuring Hope in the Philippines: Validating the Short Version of the Locus-of-Hope Scale in Filipino

A short version of the locus-of-hope Scale was developed and translated into the Filipino language for the purpose of assessing hope in Filipinos who have lower levels of education and who may not have adequate levels of proficiency in English. The 20-item scale had four locus-of-hope subscales (internal, external-family, external-peers, and external-spiritual) each with four items (another four were filler items); all items described thoughts associated with some capacity and strategy to attain important goals in life. A sample (N = 362) of adults from communities in Metro Manila were asked to answer the scale, as well as measures of optimism, self-esteem, and life satisfaction. Confirmatory factor analysis indicated an adequate fit between the hypothesized four-factor structure and the data, but the internal locus-of-hope scale was found to have low internal consistency. Regression analysis showed positive associations between the internal and external-family locus-of-hope subscales and the three measures of wellbeing. But external-peers locus-of-hope was negatively associated with optimism and self-esteem, and external-spiritual locus-of-hope was positively related with optimism.
