Study: China's one-child policy only became effective after cadre evaluation reform

Researchers trace how China's one-child policy, introduced in 1979-1980, initially produced little drop in fertility rates despite fines and penalties for violators. They find the real enforcement shift came with the 'one-vote veto' (OVV) system, which barred local officials from career promotion if their district missed birth-quota targets, a measure first piloted in Hunan's Changde prefecture in 1982 before spreading nationally by the early 1990s.

Study links China's 1990s fertility drop to official incentive changes, not one-child policy itself

A study by Meng and colleagues published in Nature finds that China's one-child policy had little effect on fertility rates during its first decade. Instead, the researchers attribute roughly half of the sharp fertility decline seen in the 1990s to a shift in how local officials were incentivized to enforce population-control measures.
