人口灰犀牛：现状、影响和应对（国金宏观张馨月）

Core Viewpoint - The key to maintaining output growth in the face of accelerating population aging is to improve labor productivity through technological advancement, increasing labor participation rates, and expanding overseas operations [2]. Group 1: Global Population Trends - The global population is transitioning through four stages of demographic transformation, with most countries having completed industrialization or being in its middle stages, leading to a decline in the demographic dividend and an increase in aging and low birth rates [5][10]. - By 2024, the global population aged 65 and older is projected to reach 10.2%, with this figure expected to rise to 13.1% by 2035, indicating a shift towards moderate aging societies [10]. - The total fertility rate globally has decreased from a peak of 5.32 in the 1960s to 2.25 in 2024, nearing the replacement level of 2.1, with developed economies facing significant challenges related to low birth rates [11]. Group 2: China's Population Challenges - China is entering a phase of accelerated aging, with the proportion of the population aged 65 and older expected to reach 15.6% by 2024, transitioning to a moderately aged society [16]. - The total fertility rate in China has fallen below the replacement level since 1991, reaching 1.0 in 2023, necessitating comprehensive policies to support childbearing and reduce the burden of child-rearing [18]. - The phenomenon of "aging before becoming rich" poses challenges for total demand and the social security system, as the elderly population's consumption capacity may be weaker than that of developed economies [20]. Group 3: Macroeconomic Impacts of Population Structure Changes - The aging population is expected to exert downward pressure on potential growth rates due to a shrinking labor force, with China's labor force participation rate declining from a peak of 74.5% in 2010 to 68.3% by 2024 [31][34]. - The aging process can lead to a negative output gap, as seen in Japan, where actual economic growth has consistently lagged behind potential growth due to demographic shifts [36]. - Population aging is associated with a shift in consumption patterns, increasing demand for services such as healthcare and elder care, which may enhance service consumption's share of total consumption [39]. Group 4: Strategies to Address Aging Challenges - Improving labor productivity is crucial to counter the negative impacts of an aging population, with technology playing a key role in enhancing productivity through automation and innovation [46][51]. - Increasing labor participation rates, particularly among women, and extending working hours can help mitigate the labor supply challenges posed by an aging population [57]. - Expanding overseas operations and attracting foreign labor can serve as effective strategies to address domestic labor shortages and enhance productivity [59][60].
