Using data from China’s 1990 and 2000 censuses, this paper examines interprovincial migration by describing its spatial patterns and estimating models based on the gravity approach. Between the censuses, interprovincial migration increased considerably in size and became more unidirectional and concentrated. Modeling results highlight the role of regional economic disparity and migration stock,...

conclusions the x-intercepts (point at which the fdc crosses the x-axis) were on average more in the base-in direction, y-intercepts (point at which the fdc crosses the y-axis) were shifted in the exo direction, and slopes were steeper in the symptomatic group. results there were more subjects with exo fixation disparity than eso fixation disparity in the study sample. the means for fixation di...
