Study on the Influence of the the Universal Two-childPolicy on China＇s Pension Payment

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.

The past, present, and future of population geography in China：Progress, challenges and opportunities

Population geography （PopGeo）, although a sub-discipline of human geography, should have been well developed in China in light of its national population size and unique demographic issues, regional socio-economic development, and biophysical differences. Yet it typically lags behind the development of its parent disciplines, especially demography and geography. Specifically, PopGeo in Chinese higher education is still at a low level in terms of the three major aspects of disciplinary development： academic majors for higher education, academic conferences, and journals. The research content of PopGeo in China has focused on the growth, composition, change, distribution, and carrying capacity of population at the meso- and macro-spatial scales. As the most populated country in the world, questions about how and why the population changes, where the population settles and migrates to, its maximum carrying capacity, and how to guide sound development of population matter to society and the economy, are always important topics in the PopGeo studies in China. In contrast, some new population phenomena such as human space-time behaviors （commuting, remittances, and friends＇ interaction）, popular in the scientific community abroad, are not fully investigated at the micro-level. Presently, PopGeo in China may face both challenges and opportunities because of the adjustment of fertility policies and implementation of na- tional new urbanization plans at the national level. It is this occasion that calls for a state-of-the-art review of the development of PopGeo since the 1980s, the turning point of an increasing number of PopGeo studies in China. We aim to reveal the current status of Pop- Geo in China to the world, and shed light on its further study.
