论文摘要
山东省的儿童比中国其他任何省都有更多的孩子。相对于其他省份的平均值，有关122,000多名儿童的数据显示出出生顺序的高度优势急剧提高。我们建议，山东的陡峭出生顺序梯度是由于对长子的偏爱，这影响了父母的生育决策和对儿童的资源分配。我们表明，在山东省内，对地区和文化的坡度更陡峭，对大孩子偏爱。正如预测的那样，该梯度也随着同胞的性别而变化。通过反向计算，山东省的陡峭出生阶段解释了山东省和中国其他地区之间平均身高差距的一半以上。
More children in Shandong Province are stunted than any other province in China. Data on more than 122,000 children show a dramatic increase in height advantage with birth order in Shandong relative to the average of other provinces. We suggest that the steep birth order gradient in Shandong is due to a preference for the eldest child, which influences parental fertility decisions and resource allocation to children. We show that within Shandong province, the gradient is steeper for regions and cultures with a high preference for the eldest child. As predicted, this gradient also varies with the sex of the sibling. By back-calculating, the steeper birth order gradient in Shandong Province explains more than half of the average height gap between Shandong Province and the rest of China.
