This paper estimates the effect of the expansion of broadband infrastructure, which enables high-speed Internet, on population development in panel of Finnish areas in the period 2010-2018. The study differs from previous studies in that it uses accurate statistics on the availability of broadband in 1 km * 1 km population grids. Therefore, the impact of broadband availability on rural development is evaluated more accurately than previously. The results of the Difference-in-difference (DiD) regression analysis show that the availability of broadband reduces depopulation of remote and sparsely populated rural areas. In this respect, the telecommunication policy in Finland has been successful, and the findings encourage the expansion of broadband infrastructure in rural areas.
本文估计了2010 - 2018年期间，芬兰各地区面板中能够实现高速互联网的宽带基础设施扩张对人口发展的影响。该研究与以往研究的不同之处在于，它使用了1公里×1公里人口网格中宽带可用性的精确统计数据。因此，对宽带可用性对农村发展的影响评估比以往更为准确。双重差分（DiD）回归分析结果表明，宽带可用性减少了偏远和人口稀少农村地区的人口减少。在这方面，芬兰的电信政策是成功的，研究结果鼓励在农村地区扩大宽带基础设施。
