内生增长要素与城乡收入差距

城乡收入产生于城乡部门不同的生产函数。其突出特征是,人力资本要素在城乡经济中的重要差别,而人力资本的差别在很大程度上决定于城乡家庭生育率的不同选择。相对于城市来说,农村地区的高生育率和低人力资本积累率所导致的低水平均衡,是农民收入增长困难的重要原因;而城市部门已进入低生育率、高人力资本存量和积累率所推动的持续增长阶段。缩小城乡收入差距政策的主要着眼点,应是促进农村家庭人力资本积累率提高和生育率下降。

The Endogenous Growth Factor and Urban-rural Income Gap

Urban-rural income produces in different production function of urban-rural department. The prominent character is the important difference of human capital factor in urban-rural economy, but the difference of human capital is decided in the different choices of urban-rural family fertility in very great degree. In comparison with the city, the low-level balance that the high fertility and low accumulation rate of human capital in countryside area cause is the reason that the farmer income grows difficultly. However, city department has already entered into continuing growth stage in which the low fertility, high human capital storage and accumulation rate remain. The mainly point of the policy of narrowing urban-rural income gap is to raise the accumulation rate of human capital and lower the fertility in countryside area.
