基于2014年和2016年中国家庭追踪调查（CFPS）数据，考察隔代照料对儿童沉迷网络的影响。研究发现：隔代照料对儿童沉迷网络具有显著的助推作用，且在稳健性检验后依然成立；父母外出也会显著促进儿童沉迷网络。进一步的异质性分析表明，对于母亲从事非农就业和跨省工作的儿童来说，隔代照料更为显著地增加其沉迷网络的可能性。

Based on the data of China Family Panel Studies (CFPS) in 2014 and 2016，this paper investigates the impact of grandchild care on children's internet addiction. The results show that grandchild care has a significant promoting impact on children's internet addiction, and the conclusion is still valid after the robustness test. In addition, this study finds that parental migration can also significantly contribute to children's internet addiction. Further heterogeneity analysis shows that for children whose mothers are engaged in non-agricultural employment and inter-provincial work, grandchild care may significantly increase the possibility of internet addiction.
