Population aging is creating serious challenges for the sustainability of China’s pension system. To mitigate the adverse impact of the demographic shift, China has recently introduced fertility and retirement policy reforms. The research presented in this paper primarily evaluates the impacts of recent reforms on the financial sustainability of China’s Urban Employees’ Pension Plan (UEPP). By using the Leslie matrix and actuarial models, the financial sustainability of the UEPP from 2019 to 2070 is projected and evaluated under a set of assumed policy reform scenarios. The results indicate that an imbalance in the pension fund would occur in the early 2020s and then expand under existing policies. Fertility adjustment, retirement delay, or combination reforms would not fundamentally solve this financial crisis in the long term. When 100% of couples have a second child and the retirement age is increased to 65, the current and accumulated pension deficits would drop by 50.05–67.56% and 35.88–54.23% between 2040 and 2070, respectively. Supplementary policy measures should be designed to encourage childbearing and retirement delay, including family support policies and top-designed pension system reform policies.

Pension inequality resulting from fragmented arrangements among different population groups – such as public sector employees, enterprise workers, rural residents, and urban informal workers – has become an essential obstacle to China’s socioeconomic development. This commentary analyzes the impacts of the 2015 pension reform on the inequality within China’s pension system. We claim that the unification of pension rules should be considered the greatest achievement in mitigating pension inequality. However, the integrated pension rules do not necessarily reduce gaps in pension opportunity and benefits among groups because of differentiation in their labor incomes as well as pension attributes. In addition, although the pension structures were flattened at the basic level, structural disparities exist at the supplementary level, strengthening unequal pension benefit outcomes. We argue that the 2015 pension reform enables public sector employees’ privileged status to continue while enterprise employees and rural residents and urban informal workers remain at the pension system’s margins.

Green spaces play an important role in improving the health and quality of life of urban residents, and environmental justice has become one of the most debated topics for scholars and governments in China. The accessibility of green space has been recognized as an effective method for the assessment of environmental justice. Population and green space are the two basic elements for evaluating green space accessibility. However, high-precision population data are difficult to obtain. To address this issue, we propose a straightforward method to assess green space accessibility using urban artificial building data and investigate how green space distribution is correlated with the population. Our analysis uses urban artificial building data and green space data from 2018 in Nanjing, China. The results show that the overall amount of green space, is not only very low, but also unevenly distributed. From the urban center to the city outskirts, the green space changed representing an M-shaped pattern, while the population sharply declined. Given the serious mismatch between the population and green space, only about 26.4% and 51.8% of Nanjing residents could access green space within 400 and 800 m, respectively, which was far below that in cities in developed countries. For residents’ wellbeing, governments must consider increasing green space provision and promoting equal access.

Rural China is experiencing a rapid aging process caused by low fertility and large-scale rural-to-urban migration, which will place an increasing payment burden on the rural pension plan. To allay the negative impact of the aging transition, China has recently carried out a demographic policy reform, replacing the famous one-child policy with the two-child policy. This paper evaluates the impacts of the demographic policy reform on the financial sustainability of China’s New Rural Pension Plan (NRPP). By applying the cohort component population projection method and building actuarial models, the solvency sustainability of the NRPP between 2019 and 2080 is estimated under six demographic policy scenarios, followed by sensitivity analysis. The simulation results show that under the one-child policy, the current and the accumulated pension fund would run deficits in 2030 and 2042, and then the pension deficits would expand rapidly. The two-child policy would relieve the pension pressure moderately before 2075, but thereafter, the pension deficits would become much worse. Sensitivity analysis of a series of demographics and pension parameters on the financial sustainability of the NRPP are displayed. On average, the long-term pension gap may not be avoided for the NRPP, regardless of raising the contribution rate, delaying the retirement age, or encouraging people to have more children.

Grandparenting is becoming increasingly prevalent worldwide, especially in Chinese society. However, the impact of grandparenting on older adults’ health remains unclear. This study examined whether and how grandparenting is associated with depressive symptoms in Chinese older adults and the role of intergenerational support (i.e., financial, emotional, and instrumental support) in this relationship. Using data from the China Longitudinal Aging Social Survey (CLASS) 2018 wave, the researchers employed multivariate linear regression models to investigate variations in depressive symptoms and their associations with grandparenting; the role of intergenerational support was also explored. The results indicated that older adults who engage in grandparenting, particularly in non-intensive care, experience a reduction in depressive symptoms, even after accounting for sociodemographic and health-related factors. Overall, intergenerational support plays a mediating role in the relationship between grandparenting and associated mental health outcomes. Bidirectional emotional and financial support and receiving instrumental support were associated with lower depressive symptoms among Chinese grandparents. In general, the findings of this study suggest that grandparenting, along with intergenerational support, provides certain protective health benefits for Chinese grandparents. With rapid changes in Chinese society, further prospective longitudinal studies are needed to examine family contexts in the relationship between grandchild caregiving and associated health outcomes.

Background: Under the dual pressures of global warming and accelerated population aging, rising temperatures pose a particularly serious threat to the older population. However, systematic evidence on the heat exposure-response pathway is still scarce. This study aims to explore the effects of heat exposure on self-rated health and its pathways in older adults in China. We predicted that heat exposure would reduce the self-rated health of older adults, and that chronic diseases and intergenerational support would mediate this effect.Methods: We linked health data from 9,670 participants in the Chinese Longitudinal Healthy Longevity Survey (CLHLS, 2008–2018 waves) with meteorological records from the National Climatic Data Center (NCDC). Individual fixed-effects models were employed to disentangle acute versus cumulative thermal effects, while Bootstrap-mediated path analysis quantified the mediating mechanisms involving chronic disease proliferation and deterioration of intergenerational support.Results: Heat exposure has a time effect on the health risk of older adults, and long-term heat exposure (β = −0.156, p < 0.01; β = −0.003, p < 0.01) significantly reduces self-rated health through the cumulative effect of health disadvantages than short-term exposure (β = 0.004, p < 0.1; β = −0.001, p > 0.1). The increase in the number of chronic diseases (β = 0.260, p < 0.05) and the weakening of children’s intergenerational support (β = −0.052, p < 0.01; β = −0.023, p < 0.01) constitute a mediating pathway at individual and household level separately.Conclusion: We found that chronic diseases and intergenerational support from children mediated the effect of heat exposure on the deterioration of self-rated health in older adults. Empirical evidence substantiates the necessity for a tiered intervention framework encompassing: individual-level chronic disease co-management protocols; household-driven initiatives to reinforce intergenerational support. This stratified approach alleviates bioclimatic risks through coordinated physiological adaptation and optimization of kinship network.
