Data for: Migration externalities in Chinese cities

Abstract of associated article: We analyse the impact of internal migration in China on natives׳ labour market outcomes. We find evidence of a large positive correlation of the city share of migrants with natives׳ wages. Using different sets of control variables and instruments suggests that the effect is causal. The large total migrant impact (+10% when one moves from the first to the third quartile of the migrant variable distribution) arises from gains due to complementarity with natives in the production function (+6.4%), and from gains due to agglomeration economies (+3.3%). Finally, we find some evidence of a stronger effect for skilled natives than for unskilled, as expected from theory. Overall, our findings support large nominal wage gains that can be expected from further migration and urbanisation in China.

相关文章摘要：本研究对中国内部移民对本地居民劳动力市场结果的影响进行了分析。研究发现，移民在城市中所占份额与本地居民工资之间存在显著的正相关关系。通过使用不同组别的控制变量和工具变量，我们提出这种影响是因果性的。大量总移民影响（当移民变量分布从第一四分位数移动到第三四分位数时，增长10%）源于与本地居民在生产函数中的互补性收益（增长6.4%），以及源于集聚经济收益（增长3.3%）。最后，我们发现一些证据表明，相较于非熟练劳动力，熟练劳动力的效应更强，这与理论预期相符。总体而言，我们的研究结果表明，随着中国进一步的人口迁移和城市化，可以预期将带来巨大的名义工资增长。
