Based on the reality that 29 Chinese provinces have already implemented the policy allowing a couple to raise a second child if either parent is an only child, this paper provides an empirical study on the effect of this policy on the financial status of the social pooling fund of basic pension insurance for urban employees. Our study suggests the followings. First, under the previous unchanged family planning policy, current deficits and cumulative deficits will occur in the social pooling fund in the year 2047 and 2063 respectively. Second, if lO% to 50% of qualified couples choose to raise a second child, the financial status of the social pooling fund will improve; relative to the previous unchanged family planning policy, the contribution ratio can decrease from 20% to the range between 18.06% and 19.57% without causing any changes to the original financial status of income and expenditure. Third, if the percentage of couples choosing to raise a second child rises to 60% to 100%, the contribution ratio can even decrease to the range between 16.55% and 17. 7% without causing any changes to the financial status as under the previous unchanged family planning policy. The above conclusions have all passed the sensitivity test. Therefore, the "two-child policy" for qualified couples is favorable to alleviating the payment pressures of pension insurance but the policy effectiveness is subject to fertility desire and the intensity of government implementation. 展开更多

From 1979 to 2012,the Chinese government implemented the one-child policy to control population growth.In 2013,families in which either parent was the only one child were allowed to apply for a second child.In 2016,China’s universal two-child policy was finally imposed.As such,many children who had always been the center of their family’s universe due to the unique family structure stemming from the one-child policy era became elder siblings during their adolescence.We report a case of a 9-year-old girl who developed seizures after the birth of her younger sister.The combination of clinical observation,laboratory examinations,and video-electroencephalography was not enough to make a confident diagnosis of epilepsy initially.Given her patient history and follow-up investigation,we speculated the two-child policy was related to her seizures.To our knowledge,this is the first report of seizures strongly related to the two-child policy. 展开更多

Family planning has been China's basic national policy since 1980, but it changed from a onechild policy to a two-child policy at the end of 2015 as which will further stimulate the rapid growth of China's population and have a profound impact on the population structure and land use in China. Based on the forecast of total population change in national and provincial dimensions after the two -child policy, the paper forecasted the spatial pattern of China's population and provincial differentiation over the next 15 years, and discussed the far-reaching impact on the future urban and rural land use and planning. Conclusions as follows: the two-child policy will achieve rapid population growth in the next 5 years, then there will be a stable growth phase;the peak of China's population increase will occur in 2030 with a total population of about 1.55 billion people, which will continue the regional differentiation of urbanization, and urbanization level in southeastern region will remain generally higher than that of the northwest. In addition, population growth brings new demands in urban and rural construction land, therefore, more intensive use of land will be the inevitable choice for the future development for China. 展开更多

The most essential step in adjusting and improving the childbearing policy, the universal two-child policy will produce far-reaching impacts on the future development of China’s population. With its implementation, the country’s total population will peak later, the underage population and its proportion will increase substantially, the working-age population will experience a slower decline, and the aging of China’s population will be eased. However, the drop in the proportion of working-age people over the last 15 years has expedited the reduction of the demographic dividend, the elderly population will remain unaffected over the next 60 years, the aging of the population will continue to deepen, and at the same time, the increased child dependency burden will expand the overall dependency ratio. 展开更多

In the face of the continuous decline in the birth rate and the aging of the peak of aging, following the implementation of the "Decision of the Central Committee of the Communist Party of China on Comprehensively Deepening the Reform of Some Major Issues" adopted by the Filth Plenary Session of the 18th CPC Central Committee on November 15, 2013, the party is the only child. Female couples can have a policy of giving birth to two children. On October 29, 2015, China introduced the "two-child policy", completely replacing the "one-child policy" that has been implemented in China for more than 30 years. The "two-child comprehensive" can alleviate the unfavorable population trend that plagues China's social security system to a certain extent. Optimize the age structure of the population and increase the supply of labor. However, for a long time, the financial distress and management dilemma faced by China's pension payment still exist, and the loose population birth policy will have a great impact on reducing pension payment, and will gradually appear in the policy implementation. This article combines the "comprehensive two-child" policy, focusing on the role of the new population birth policy to alleviate the pressure on China's pension. 展开更多

Purpose:China’s new universal two-child policy has brought a baby boom of the second child in 2016.With the changing family structures,elder children in adolescence may have more and more emotional and even psycholog­ical problems such as“two-child syndrome”.This paper aims to explore the“influence factors and mechanism of the second child on the growth of teenagers”and has great practical significance to promote the physical and mental health of teenagers and the harmony of two-child families.Design/methodology/approach:By means of literature analysis,in-depth interview,questionnaire survey and statistical analysis,the elder children aged 12 to 18 in the two-child family were taken as the main body of the survey,and an empirical research based on NLP understanding hierarchy theory was carried out.Major Findings:(1)The most significant influence on the growth of teenagers is the attitude of parents,and then the gender of the first child.(2)Parents’favouritism towards the second child would lead to decline in the first child’s academic performance.(3)The higher the family income,the less the influence on the first child’s life.(4)When the age difference is large,the first child and the second child are not easy to have conflicts.Practical implications:Parents should try to treat any children equally.Parents should pay attention to the sibling relationship of their two chil­dren with small age gap.Parents who have two children with a large age gap should properly guide the elder child to help take care of the younger brother or sister.Originality/value:This study contributes to the growing literature focus­ing on the influence factors and mechanism of the second child on the growth of teenagers in the context of China’s new universal two-child policy.It adds some early empirical insights on the physical and mental health of teenagers in two-child families. 展开更多

The impact of family size on female participation in the labor market has long intrigued economists,with inconclusive findings.This paper examines the dynamic effect of having a second child on female workforce participation in China by utilizing the 2015 universal two-child policy as a quasi-natural experiment.Using data from the China Family Panel Studies and employing the difference-in-differences model,this study found that for policy-targeted women,the net effect of having a second child on their workforce participation was insignificant following the policy's implementation.However,upon further exploration of the time-varying effect,it was discovered that in the first two years after they gave birth,policy-targeted women were significantly less likely to enter the workforce due to child-care needs.However,influenced by increased household economic pressure,the likelihood of women entering the workforce increased significantly in the fourth year after giving birth.These results indicate that the effect of a second child on female workforce participation was not uniform and displayed temporal variability.This study enriches the existing literature on how family size affects female workforce participation and contributes to a deeper understanding of the effects of relaxed fertility policies. 展开更多

China recently instituted a two-child policy in response to its aging population, declining workforce and demographic dividend, and the need to develop asocial economy. Additionally, women generally delay having a second child because of the overwhelming pressure in their lives. With the improvements in assisted fertility technologies in recent years, the number of elderly women attempting to bear children has increased. The quality of woman's eggs and a man's sperm declined dramatically with increasing age, leading to an increased risk of pregnancy-related complications among older women. Therefore, the types of fertility problems experienced by elderly females must be provided with considerable attention by obstetricians. This commentary article focuses on the medical problems faced by older second-child pregnant women. This work discusses their increased rates of infertility, spontaneous abortion, fetal malformation, gestational diabetes, cesarean section, placenta previa, postpartum hemorrhage, postpartum depression, and hypertensive disorders, which complicate pregnancy. 展开更多

The universal two-child policy,implemented in October,2015,is considered to be the most significant adjustment in the history of China's family planning program.Using data from the 2014 national population sampling survey,this paper employs a population group-component calculation and projection method to compute the number of target population in 2016 and then to estimate the number of extra births that are likely to result from implementation of the universal two-child policy.The results show that the total number of extra births is estimated to be approximately 17.2 million in the years 2017-2021,with the number of extra births per year ranging from approximately 1.6 to 4.7 million.This will lead to a dramatic shift in China's TFR from an estimated 1.6 in 2016 to one approaching the replacement level,and then dropping to a projected 1.7.With the universal two-child policy in place,China's total population will grow to about 1.45 billion around 2028 and then gradually begin shrioking.The labor force will become larger under the universal two-child policy than it would if the stricter birth control policy were maintained,with an estimated 50 million additional people aged 15-59 in 2050.With implementation of China's new fertility policy,an estimated 34%of the population will be over 60 years of age in 2050,almost three percentage points lower than the level if the former fertility policy were continued. 展开更多
