In an unprecedented national move, the Chinese government has begun offering 3,600 yuan (£375; $500) annually for each child under the age of three, retroactively from 2024. The policy is China’s first centralised attempt to financially incentivise childbirth since the one-child policy was lifted nearly a decade ago. But as the world’s second-largest economy stares down a looming demographic crunch, the question remains: can subsidies alone reverse deep-seated economic and cultural trends?

From Demographic Dividend to Demographic Drag

China’s fertility rate has plunged below the replacement level, which is around 2.1 children per woman. In 2024, just 9.54 million babies were born — a marginal uptick from the previous year, but still insufficient to offset an ageing and shrinking population. The long shadow of the one-child policy, enforced from 1980 to 2016, still looms large. That policy once boosted per capita income by limiting population growth. But now, with an ageing labour force and growing dependency ratios, the country is shifting from a demographic dividend to what economists call demographic drag — when fewer workers support more retirees, depressing economic growth.

Subsidies as a Tool of Pronatalist Policy

The new cash handout — capped at 10,800 yuan per child — targets the rising cost of raising children, long identified as a key deterrent to larger families. According to a study by the YuWa Population Research Institute, it costs an average of $75,700 to raise a child in China to the age of 17 — a figure that rivals, and in some cases exceeds, costs in wealthier OECD nations when adjusted for income.

From an economic standpoint, this subsidy acts as a conditional transfer payment, intended to alter household behaviour. It is classic incentive economics: reduce the cost, increase the quantity. But will it work?

Elasticity of Fertility: Is Money Enough?

The underlying issue is elasticity of fertility with respect to income support — in simple terms, how responsive are families to financial incentives when deciding whether to have more children? Evidence from other countries such as South Korea, Japan, and parts of Europe suggests that while cash transfers can move the needle, they rarely lead to sustained fertility increases unless paired with broader structural reforms.

That’s why cities like Hohhot and Shenyang are experimenting with more generous local schemes — up to 100,000 yuan per third child, or monthly payments. And Beijing’s recent call for universal preschool planning signals an awareness that it’s not just about baby bonuses, but about long-term family policy ecosystems — maternity leave, affordable childcare, housing, and work-life balance.

Labour Supply, Growth, and the Big Picture

A shrinking population means fewer workers, a challenge for a country whose rapid growth has historically depended on a large, low-cost labour force. This raises questions about China’s future labour supply, potential output, and the long-run shape of its aggregate supply curve. With the working-age population shrinking, the economy may face higher wage pressures, reduced productivity growth, and rising fiscal burdens from age-related spending such as pensions and healthcare.

Meanwhile, if the birth rate continues to fall, human capital accumulation could decline unless offset by increased investment in education and skills.

Can the Invisible Hand Rock the Cradle?

Ultimately, the Chinese government is betting that economic incentives can tilt the scale of one of the most personal decisions people make. Yet economics teaches us that incentives matter, but so do constraints. Cultural norms, career aspirations, housing costs, urban living pressures, and gender roles all play powerful roles in fertility decisions.

For China, tackling its demographic future will require more than cash. It demands a holistic reimagining of how work, family, and state intersect. This policy marks a start — but the real labour has only just begun.
