China’s Fertility Puzzle: Why the Universal Two-Child Policy Fell Short of Expectations

Chinese scientists Hanming Fang and Chang Liu have published a pivotal analysis in the Journal of Development Economics that examines the gap between desired and realized fertility under China’s Universal Two-Child Policy. Their research, set for publication in the June 2026 issue, provides a rigorous economic framework for understanding why a major policy shift did not produce the expected surge in births.

The study is significant because it moves beyond simple population projections to explore the structural, economic, and behavioral factors that constrain family formation in contemporary China. By focusing on the discrepancy between stated fertility preferences and actual childbearing outcomes, the researchers identify core tensions in China’s social and economic system — including rising costs of child-rearing, housing pressures, and shifting gender roles — that the policy alone could not resolve. This work is an essential contribution to the global conversation on how governments can effectively design family-support policies in rapidly modernizing economies.

For China’s scientific and policy communities, this analysis underscores the need for integrated strategies that couple population policy with broader economic reforms. It serves as a clear signal that demographic engineering, without addressing underlying socioeconomic realities, has limited power to alter long-term trends. The findings carry direct implications for China’s labor market stability, innovation capacity, and long-term economic growth prospects.

Why it matters:
For global economists and policymakers, this research provides a critical case study on the limits of pronatalist policies, demonstrating that shifting population trajectories requires far more than removing legal barriers — it demands deep structural changes to housing, education, and gender equality.
