Abstract The upgrade of legacy infrastructure is a challenging undertaking in general. The underlying issues are especially prominent for telecommunications networks outside of urban areas. Using German micro-level data, we identify the structural determinants for fiber optics deployment and its extent. We also measure the role of technology competition from the existing infrastructures, VDSL-Vectoring and TV-Cable. In this setting and exploiting a natural experiment, a technologically restrictive policy as proposed by the European Commission is found to be ineffective in promoting fiber deployment. Policy interventions in the form of subsidies targeted at specific local infrastructure projects, however, raise the likelihood of fiber deployment by a substantial margin. A targeted, proactive policy approach is therefore needed to overcome structural and geographical disadvantages.

光纤与矢量:限制宽带扩展中的技术选择

摘要 传统基础设施的升级是一项具有挑战性的工作。对于城市地区以外的电信网络,潜在问题尤其突出。使用德国微观数据,我们确定了光纤部署及其范围的结构决定因素。我们还衡量了来自现有基础设施、VDSL-Vectoring 和 TV-Cable 的技术竞争的作用。在这种情况下并利用自然实验,发现欧盟委员会提出的技术限制政策在促进光纤部署方面无效。然而,针对特定地方基础设施项目的补贴形式的政策干预大大提高了光纤部署的可能性。有针对性的,
