Abstract
This paper builds on and extends the literature on the linkage between firm productivity and their export destinations to study the productivity of Chinese firms and their sales destinations in other provinces within China. Moving the study from international markets to domestic markets conveniently avoids the hard to control heterogeneity across different destination markets in international trade, as provincial markets within China are less heterogeneous than international markets but segmented by Chinese provincial borders. The paper explicitly controls the fact that many firms only sell in their home provinces by using the zero‐inflated negative binomial method. It finds that firms with higher productivity tend to sell in other provincial markets, and more productive firms enter more provincial markets. The results are robust . ( JEL F15, D21, D24)

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
