Prediction of the intercity migration of Chinese graduates

We investigate the intercity migration of Chinese graduates from their hometowns to their work destinations. Motivated by the gravity model, which is a common tool for predicting human migration and movement, we introduce a new model that considers the following three factors: economy, administration and study location. The resulting model can predict the migration flux of graduates in good agreement with the observed flux. The prediction results for the migration flux of graduates with different degree levels and the discrepancies among these graduates, with respect to the dependence of the flux on the three factors in the model, are obtained.
