The Impact of Improving the Pension Financial System on an Aging Society

China is rapidly entering a deeply aging society, with the proportion of the population aged 60 and above exceeding 18.7%. Currently, the existing pension financial system faces severe challenges such as an imbalance in the three-pillar structure and a continuous decline in the pension replacement rate. This study focuses on exploring the critical role of improving the pension financial system in alleviating the pressure of aging, systematically analyzing its economic and social benefits as well as the existing obstacles. By integrating policy documents, market data, and academic research findings, the study reveals that a multi-pillar pension system can significantly reduce fiscal burdens and provide a stable long-term cash flow. However, the current supply of pension financial products is heavily concentrated on savings-based products, with development gaps between eastern and western regions reaching up to five times, and insufficient risk management capabilities, all of which constrain the overall effectiveness of the pension financial system. Based on this, the study proposes specific pathways such as deepening composite product innovation (e.g., introducing pension insurance embedded with care services), building cross-departmental data platforms, and implementing regionally differentiated policies. These aim to construct a modernized pension financial safety net tailored to China's national conditions, providing a reference for relevant decision-making.
