It is found that the ideal number of children for the Chinese trended downwards from 1980, but since 2000 the average number has remained basically stable at 1.6 to 1.8. In the 1980s, people's fertility levels were higher than their fertility intentions. With economic and educational progress in China, both fertility levels and fertility intentions showed a downward trend, with the former declining faster than the latter. Since 1990, people's fertility levels have been lower than their fertility intentions; that is, their actual number of children has been less than their ideal number. This provides an empirical basis for examining the changes in China's fertility intentions and fertility levels.展开更多

Based on the theory of the transformation of intimacy, this study utilizes the data from the Xi'an Special Survey on Child Rearing Costs and Fertility Intentions to explore the impact of spousal relationships on the fertility intentions of young urban couples and gender differences in this regard in terms of power relations, distribution of responsibility, and emotional connection. The study reveals that 1) an inverse J-shaped relationship(initially showing a decline followed by a rise) exists between family power equalization and fertility intentions, especially for women;2) the greater the husband's share of housework, the less he will desire fertility, but a wife's level of satisfaction with her husband's housework sharing increases her fertility motivation;and 3) frequent spousal interactions and emotional intimacy contribute to increased fertility intentions, especially on the part of women. From the perspective of the transformation of intimacy, the above results suggest that the impact of spousal relationships on young couples' fertility intentions is increasingly strong and that continued promotion of gender equality in the family sphere is of great significance to reversing low total fertility rates.展开更多

The superimposed effect of an aging population and low birthrate leading to a reduction in the labor supply would have a fundamental influence on the long term balanced development of China's population, implying that China's population policy must be adjusted. This paper argues that a gradual relaxation of the family-planning policy adjustments accords with the original intention of the population policy design and development direction. The universal second-child policy is the logical results of the adjustment and improvement of China's family-planning policy, and is designed to bring about positive effects on future demographic and economic development, particularly in sustaining the long term balanced development of China's population, easing the marriage squeeze, extending the demographic dividend, and delaying the population aging process. China needs to develop and improve support and governance systems for fully implementing the universal second-child policy, realizing the policy transition from rewarding one-child families to population security and the modern transition of governance systems and capacity to a universal second-child policy.展开更多
