摘要

我们采用控制函数方法，辅以各种识别策略，从2010年到2015年，对德国46个两位数制造业和服务业的宽带可用性对企业全要素生产率（TFP）的异质性影响进行了因果估计。在此期间，宽带的可用性（定义为访问传输速率至少为16mbps）在德国各城市增加了一倍多。我们的研究结果表明，虽然宽带可用性对制造业企业的生产力影响微不足道，但它对许多服务部门产生了显著且高度异质性的影响，估计信息和通信服务部门的平均增幅高达6.8%。

Broadband and productivity: Structural estimates for Germany

We employ a control function methodology, complemented by various identification strategies, to causally estimate the heterogeneous effects of broadband availability on firms’ total factor productivity (TFP) across 46 two-digit manufacturing and service industries in Germany from 2010 to 2015. Throughout this period, the availability of broadband, defined as access to transmission rates of at least 16 Mbps, more than doubled across German municipalities. Our findings reveal that, while broadband availability had a negligible effect on the productivity of manufacturing firms, it exerted a significant and highly heterogeneous impact in numerous service sectors, with an estimated average increase of up to 6.8% in information and communication services.

期刊介绍： The Journal of Economic Behavior and Organization is devoted to theoretical and empirical research concerning economic decision, organization and behavior and to economic change in all its aspects. Its specific purposes are to foster an improved understanding of how human cognitive, computational and informational characteristics influence the working of economic organizations and market economies and how an economy structural features lead to various types of micro and macro behavior, to changing patterns of development and to institutional evolution. Research with these purposes that explore the interrelations of economics with other disciplines such as biology, psychology, law, anthropology, sociology and mathematics is particularly welcome.
