亚洲女性收入对生育率影响的国际比较研究--基于劳动参与率、受教育程度、就业方式的视角

通过构建家庭效用函数模型,论证了家庭收入增长中女性收入对家庭生育决策的影响,说明了随着女性收入的提高,会降低生育率。进一步,通过引用女性劳动参与率、受教育程度及就业方式作为女性收入对生育率影响的中间变量,再运用相关数据进行实证分析,发现女性劳动参与率、受教育程度对生育率有着负向的影响,而女性非全日制就业方式对生育率有着正向的影响。再进一步,对亚洲各国生育政策的调整进行国际比较,探讨生育政策的具体措施与影响女性收入的三个因素之间的关系,最后针对中国目前的生育水平提出两方面的建议：硬政策的完善和软环境的支持,以有助于提高人口素质,优化人口结构。     

An analysis of variations in U. S. fertility and female labor force participation trends

This study is based on time series data from 1947–1977 on fertility and female labor force participation, and examines (a) the effects of male relative income and female earnings on the level and timing of fertility and female labor force participation, and (b) the relative importance of variations in relative income and female wage rates in explaining the fluctuations in both fertility and female labor supply. The results suggest that relative income exerts a significant positive effect on fertility and a negative effect on female work effort. However, female wage rates appear to be the dominant factor in explaining variations in fertility and female labor force participation over the past two decades, with increases in female earnings leading to both depressed fertility and increased labor force participation of women.     

生育率的经济学分析

本文在前人研究的基础上,从经济学角度分析了家庭收入对生育决策的影响,并尝试进一步推导出“收入-生育率”曲线。与以往研究不同的是,本文认为生育率与家庭收入并不总是呈反向关系,而是收入到了一定水平以后,生育率水平又会随之上升,即“收入-生育率”曲线基本呈扁平“U”形曲线形态。     

家庭子女养老与个人养老“互补替代”效应：理论与实证

依据生命周期均衡收入分配原理,构建家庭子女养老和个人养老收入分配适度水平及其"互补替代"数理模型,从理论和实证角度研究家庭子女养老和个人养老经济结构优化。研究发现:(1)家庭子女养老和个人养老收入分配存在"替代"关系,而在退休年龄延长的条件下,二者存在"互补"关系;(2)家庭子女养老和个人养老替代的均衡点是家庭有2个子女,随着子女数量的增加,家庭子女养老与个人养老边际替代率递减;(3)伴随老年人寿命的延长,家庭子女养老收入再分配系数下降,个人养老收入分配系数上升且上升幅度大于前者下降幅度;(4)家庭子女养老与个人养老之间的"互补替代"效应呈现为"倒V形"曲线,且其替代的均衡点与总和生育率2.1的更替水平存在契合效应。     

中国农村居民家庭的生育决策模型与实证分析

根据"五普"和"六普"资料,人口总和生育率显著低于世代更替水平,这表明中国人口进入了低生育水平发展阶段。关于这一问题的合理解释是除了计划生育政策影响外,农村家庭生育决策的变化可能是内生的重要影响因素。基于生育决策模型及实证分析,得出这样的结论:在土地量保持不变的条件下,农村居民家庭的生育决策主要取决于收入水平和抚养子女的成本。农村居民家庭可能会依据"量质权衡"减少生育子女,这可能是导致中国人口生育水平下降的根本原因。     

Economic considerations in family growth decisions

Abstract Examination of the fertility patterns of a sample of white Detroit couples at selected stages of the family life cycle indicates that, in a large American metropolis, family income is more closely related to the time when a family is formed and has its children than to the number of children it expects to have. In a longitudinal study, current income is strongly related to the timing of demographic events-the age at marriage, whether pre-maritally pregnant, the time interval from marriage to a given parity, and fertility during a two-year follow-up period. This paper also explores the hypothesis that a family's evaluation of its economic position and the choices it makes about important family expenditures has a relation to fertility apart from the family's objective current income level. Couples who consider their income adequate for their needs or relatively greater than that of their friends or peers, and those who expect substantial increases in the future, tend to expect more children than those who do not. Small but consistent differences obtain over the parities studied. Variables indexing alternative family expenditure patterns, such as cars, or savings for college education for children, are associated with lower family size expectations and longer spacing patterns.     

The effects of income level,income distribution,education and urbanization on fertility rates among 28 administrative regions of China

Conflicting empirical evidence on the role of income distribution on fertility rates is the impetus for this 1982 study of providence-specific Chinese Census data, excluding Tibet. The findings support the prior thesis of Repetto but utilize the micromethods and per household income measures of the competing findings of Boulier. It is cautioned that in the Chinese analysis equal income distribution depresses fertility, but China may not reflect world wide patterns. China did not have until recently a market incentive system, and there are income measurement problems. The data are per capita economic output not per capita income, and those high output areas which did not produce low fertility may actually have had households with low incomes. The importance of this research is in establishing that cross-province data are a useful tool in understanding the influence of income distribution on fertility. As with most developing countries, women's education, for instance, at least junior high education explained the largest variation of fertility differences among the 28 provinces. The urbanization variable when controlling for income was positive, unlike the other developing countries. The 1949 Chinese government's spatial industrial policy encouraged urbanization and industrialization in rural areas and family planning programs such that highly urbanized provinces have low population density. A variety of variables on income level, income distribution, education, and urbanization are discussed. OLSQ regressions were generated utilizing such independent variables as output per capita in yuan (YOUTHPC80), the square of YOUTHPC80 (YOUTHPC802), YOUTHPC80 multiplied by the average family size in each province (YOUTHPH80), and the squared value of YOUTHPH80.     

Family allowances and fertility: Socioeconomic differences

This article explores socioeconomic differences in the effect of family allowances on fertility. Although several studies have examined the relationship between cash benefits and fertility, few studies have addressed the possible differential effects of cash benefits on families of different income or education levels. I reconstructed the birth histories of women in the past two Israeli censuses of 1983 and 1995 to study socioeconomic differences in the effect of family allowances up to the seventh parity. The results indicate that family allowances have a significant effect at every parity. Using female education as an indicator of socioeconomic status, I find that socioeconomic status is a significant modifier of the effect of family allowances. Family allowances seem to have a relatively large impact on more-educated women.     

An attempt at evaluation of the economic and social factors [influencing] the Polish population's fertility formation

This analysis of economic determinants of fertility in Poland shows that couples' fertility decisions are negatively influenced by factors affecting family income. Social and demographic factors were found to be unrelated to fertility. 17 socioeconomic measures were grouped as those expressing the level of economic development and determining family income size, those reflecting the level of socioeconomic development and determining the level of children's education, and those characterizing the level of social development and determining the need for health care and social security. The level of actual fertility is modeled as a linear function of variables in a main components factor analysis. Average monthly pay in the national economy (37.6%), the sold industrial production per person (13.8%), and the global agricultural production per person (13.2%) account for 64.6% of the variance. Among the social factors, findings indicate that a higher feeling of security is related to lower fertility, but economic factors have a stronger influence. Voivodeships are grouped as having low levels of economic development (24), as having high educational levels (24), and as having low levels of social security (24). Voivodeships with low levels of economic development and high parity include all the grouped voivodeships with the exception of three. Low-security voivodeships showed mixed patterns of fertility. High-education voivodeships showed a weak correlation with high fertility. Only three voivodeships have low economic and security factors and high education factors, and only one voivodeship has high fertility. Of the three voivodeships with high security and economic factors and low education factors, all have low parity.     

Causes of fertility decline in Eastern Europe and the Soviet Union II

Abstract The first part of this study (which appeared in the preceding issue of Population Studies) assessed the extent of the decline in fertility in the countries of the area during the last 10-15 years, and analyzed the purely demographic aspects ofthis phenomenon. Part II examines the socio-economic differentials in fertility, with regard to such variables as urban-rural residence, socio-occupational and employment status of women, educational attainment, income and housing conditions, and the consequent impact of structural changes in these characteristics of the population on observed fertility trends. The broad conclusion is that the fertility differentials usually found in western societies are also relevant to the socialist countries of eastern Europe, and that the dramatic falls in fertility in the 1950's and the 1960's have largely been the outcome ofthe deep and rapid structural changes, particularly those associated with urbanization, educational attainment and the incidence of female employment. The last part of the study is concerned with the impact on post-war fertility trends of social legislation and of general economic policies, particularly in the fields of employment and income. An appraisal of the extent of family planning is followed by a discussion of the recent pro-natalist measures introduced in most countries of the area and of their effectiveness.

Mexican fertility has remained at a high level (a crude birth rate of 42–46) in spite of rapid economic development and its concomitants: rising levels of urbanization, education, income, and female labour force participation, and falling levels of infant mortality and agricultural population, combined with rural-urban migration.

Data on child-woman ratios and children-ever-born statistics, for Mexico and each state, suggest that the constant crude birth rate is not masking age or region-specific declines in fertility.

Cross-section regressions are employed in an attempt to explain Mexico’s paradoxical fertility behaviour. Using measures of income, education, urbanization, occupational status, industrial composition, labour force participation, and the sex ratio, in a weighted log-linear form, a large portion of the variation in state adjusted child-woman ratios is explained by the ‘demographic transition’ variables. The only two which might possibly explain the trend in Mexican fertility are the income variable and the sex ratio, which have positive influences on Mexican fertility in 1960 and 1970.     

禀赋、场域与中国妇女生育意愿研究

利用2006年中国健康营养调查(CHNS)数据,构建模型,对中国18～52岁妇女的意愿生育决策、生育强度及其影响因素进行实证分析。在众多因素中,家庭已有孩子构成、能力禀赋、资本禀赋对妇女生育意愿有着显著影响,技术禀赋对妇女再生育的意愿和强度有重要影响。同时,将划分生育场域边界的地区变量纳入模型,显示不同区域间妇女的生育意愿存在较大差别,中西部地区妇女的生育意愿明显高于东北部地区;妇女禀赋条件越改善、禀赋水平越高、生育场域越优化,其生育意愿、生育强度越低,生育行为越趋理性。未来开展人口和计划生育工作,制定、调整人口和计划生育政策,应该对此予以充分考虑。     

Female status and fertility behaviour in a Metropolitan Urban area of Bangladesh

The paper examines hypotheses that certain aspects of status of married women such as (i) decision-making power; (ii) employment status and (iii) educational status, are positively associated with use of contraception and inversely related to fertility performance. The study is based on 1,130 women of reproductive age (15-49) who are currently married and living with their husbands and reported to be fecund. The data are drawn from a cross-section of working and non-working women of Dacca City. The hypothesis that each of the above status variables is related to fertility behaviour (measured as current use of contraception and number of children ever-born) is confirmed, with the sole exception of the relationship between female employment status and fertility behaviour. Female participation in the labour force has little or no effect on use of contraception, particularly among those who belong to higher education and income groups. However, in the lower education and income groups, fertility and use of contraception vary with work experience. The findings clearly point out the need to improve the status of women in order to achieve a breakthrough in the use of contraception and a reduction in fertility.     

Population growth and poverty in the developing world

The links between rapid population growth and the absolute poverty currently affecting 780 million people in the developing countries (excluding China and other centrally planned economies) were examined. Absolute poverty is defined as having less than the income necessary to ensure a daily diet of 2150 calories per person ($200 per person a year in 1970 United States dollars). Focus is on poverty and demography in the developing world (defining poverty; income, fertility and life expectancy; demographic change and poverty), effect of poverty on fertility, family planning programs and the poor, and the outlook for the future. Rapid population growth stretches both national and family budgets thin with the increasing numbers of children to be fed and educated and workers to be provided with jobs. Slower per capita income growth, lack of progress in reducing income inequality, and more poverty are the probable consequences. Many characteristics of poverty can cause high fertility -- high infant mortality, lack of education for women in particular, too little family income to invest in children, inequitable shares in national income, and the inaccessibility of family planning. Experience in China, Indonesia, Taiwan, Colombia, Korea, Sri Lanka, Cuba and Costa Rica demonstrate that birthrates can decline rapidly in low income groups and countries when basic health care, education, and low-cost or free family planning services are made widely available.     

Recent fertility in Mexico: measurement and interpretation

Summary Mexican fertility has remained at a high level (a crude birth rate of 42-46) in spite of rapid economic development and its concomitants: rising levels of urbanization, education, income, and female labour force participation, and falling levels of infant mortality and agricultural population, combined with rural-urban migration. Data on child-woman ratios and children-ever-born statistics, for Mexico and each state, suggest that the constant crude birth rate is not masking age or region-specific declines in fertility. Cross-section regressions are employed in an attempt to explain Mexico's paradoxical fertility behaviour. Using measures of income, education, urbanization, occupational status, industrial composition, labour force participation, and the sex ratio, in a weighted log-linear form, a large portion of the variation in state adjusted child-woman ratios is explained by the 'demographic transition' variables. The only two which might possibly explain the trend in Mexican fertility are the income variable and the sex ratio, which have positive influences on Mexican fertility in 1960 and 1970.     

Puzzles and further explorations in the interrelationships of successive births with husband’s income,spouses’ education and race

When fertility is examined in the detail of individual parity progressions and birth-order transitions, important interactions between the effects of income and education are seen. Among the findings are: the negative effect of education on fertility is stronger at all parities for less educated compared to more highly educated women. Additional income has a more positive effect for more highly educated than for less educated women. For women with 0-8 years of education the effect of more income is positive when the family has no children but negative thereafter, but for college-educated women the effect of more income is positive. And additional income has a less positive (more negative) effect on fertility among nonwhites than among whites.     

How female education affects reproductive behavior in urban Pakistan

Although Pakistan remains in a pretransitional stage (contraceptive prevalence of only 11.9% among married women in 1992), urban women with post-primary levels of education are spearheading the gradual move toward fertility transition. Data collected in the city of Karachi in 1987 were used to determine whether the inverse association between fertility and female education is attributable to child supply variables, demand factors, or fertility regulation costs. Karachi, with its high concentration of women with secondary educations employed in professional occupations, has a contraceptive prevalence rate of 31%. Among women married for less than 20 years, a 10-year increment in education predicts that a woman will average two-fifths of a child less than other women in the previous 5 years. Regression analysis identified 4 significant intervening variables in the education-fertility relationship: marriage duration, net family income, formal sector employment, and age at first marriage. Education appears to affect fertility because it promotes a later age at marriage and thus reduces life-time exposure to the risk of childbearing, induces women to marry men with higher incomes (a phenomenon that either reduces the cost of fertility regulation or the demand for children), leads women to become employed in the formal sector (leading to a reduction in the demand for children), and has other unspecified effects on women's values or opportunities that are captured by their birth cohort. When these intervening variables are held constant, women's attitude toward family planning loses its impact on fertility, as do women's domestic autonomy and their expectations of self-support in old age. These findings lend support to increased investments in female education in urban Pakistan as a means of limiting the childbearing of married women. Although it is not clear if investment in female education would have the same effect in rural Pakistan, such action is important from a human and economic development perspective.

Relative income and fertility

The present study examines the relationship between relative income (i.e., actual income in relation to the expected income of one’s socioeconomic group) and fertility, using data collected by the 1967-1968Canadian Family Growth Study (Balakrishnan et al., 1975). We broaden the tests of relative income beyond cumulative fertility to spacing behavior and then examine some of the assumptions included in the relative income model of fertility. Results of the tests, in brief, are as follows: (a) Relative income is found to be more closely related to spacing than to cumulative fertility; and (b) the relationship between relative income and fertility is strongest among those couples who plan their life ahead and have a high level of education and occupation, and when temporal alignment is brought between the measures of relative income and fertility. For the relative income model to receive confirmation, it was specified that the following hypotheses must be confirmed: (a) that fertility behavior would vary positively with relative income but the fertility norm would show no relationship with relative income; and (b) that consumption norms and behavior would show no relationship with relative income. The outcome of these tests are in the expected direction, giving support to the relative income model. In addition, there is some evidence of predictive capability of the relative income model for correlative behavior.     

Family and economic growth: A review

The interplay between fertility decisions and per capita growth of income by investment decisions in human capital constitutes the key element of growth models based on the microeconomic theory of family behavior. A strategy that raises the fixed cost per child, reduces the cost of education, stimulates the accumulation of human capital, diminishes the opportunity cost of parents to send their children to school, encourages female activity, accelerates economic development and contributes to a reduction of inequality.
