Migration policies on migrant–native marriage: A multilevel analysis of 43 Chinese cities
Bibliographic record
Abstract
Abstract China's household registration ( hukou ) system creates internal migration patterns similar to international patterns. Variations in the stringency of city policies for acquiring local hukou provide a unique opportunity to examine how migration policies affect migrant–native marriage. In this study, we merge a city‐level index that measures the overall difficulty of obtaining local hukou in 43 Chinese cities with China's 2005 mini‐census. Results from multilevel logistic regression models reveal that migration policies have heterogeneous effects on intermarriage. For migrant men, as it becomes more difficult to acquire local hukou , it becomes less likely that a less educated migrant man will marry and more likely that a better educated migrant man will marry a local hukou holder. For migrant women, their likelihood of intermarriage does not vary much with the stringency of hukou policies. These findings suggest that migration policies reinforce inequality between migrants and natives and within the migrant population.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
