Based on panel data of 116 countries in 2014–2019, this paper investigates the association between mobile broadband speed and labor productivity. It finds no robust contemporaneous relationship for the total sample, but there is a significant and robust association when a one-year lag of mobile broadband speed is introduced. The interpretation of the results is that a 10 percent increase in mobile broadband speed in period t-1 is associated with 0.2 percent increase in labor productivity, ceteris paribus. The results are only robust for non-OECD and low-income countries, respectively.

移动宽带速度的经济影响

基于2014-2019年116个国家的面板数据，本文研究了移动宽带速度与劳动生产率之间的关联。它发现整个样本没有稳健的同期关系，但当引入移动宽带速度一年滞后时，存在显着且稳健的关联。对结果的解释是，在 t-1 期间移动宽带速度提高 10% 与劳动生产率提高 0.2% 相关，在其他条件不变的情况下。结果仅对非经合组织国家和低收入国家分别是稳健的。
