Abstract

This paper investigates the impact of broadband Internet on the provision of public media in a large developing country. We use new panel data on public broadcasting at the province level from 2005 to 2017 and a control function approach exploiting variation in China's centralized roll-out of digital infrastructure. We find that rising broadband penetration has substantial negative impacts on the quantity of public media provision—including news, public-service programs, and entertainment—in China's local radio and television. Except for news, these effects are driven by changes in both the extensive margin (i.e., fewer channels) and the intensive margin (i.e., less broadcasting per channel). While industry ad revenues decrease significantly, ad intensity and volume per channel increase with higher broadband penetration rates. Lastly, we find that broadband Internet attracts young, educated, and urban viewers away from television but has no effect on the elderly, the less educated, and those with low-paying jobs.

宽带互联网对公共媒体的影响:来自中国的证据
本文调查了宽带互联网对一个发展中大国公共媒体供应的影响。我们使用了2005年至2017年省级公共广播的新面板数据,并采用了控制函数方法,利用了中国数字基础设施集中部署的变化。我们发现,宽带普及率的提高对中国地方广播和电视提供的公共媒体数量(包括新闻、公共服务节目和娱乐)产生了实质性的负面影响。除新闻外,这些影响是由广泛边际(即更少的频道)和密集边际(即每个频道更少的广播)的变化驱动的。虽然行业广告收入显著下降,但随着宽带普及率的提高,每个频道的广告强度和数量却在增加。最后,我们发现宽带互联网吸引了年轻的、受过教育的和城市的观众远离电视,但对老年人、受教育程度较低的和低收入的人没有影响。
