本文描述了1950-95年152个国家的年度实物基础设施存量数据库。该数据库包括对基础设施的六个指标的估计：电话数量、电话主线数量、发电能力千瓦、道路总里程、铺设的道路里程和铁路线里程。报告了原始数据集和经过处理的数据集，在这些数据集中，已将系列联系起来，以克服定义和覆盖范围的变化。其中包括一些衡量基础设施质量的指标，如道路状况较差的百分比、无法通过的本地电话呼叫百分比、可供使用的内燃机车百分比以及配电系统损失的电力百分比。除道路总量外，所有序列的数据都具有相当好的质量，应该对研究人员有用。文章还给出了基础设施存量与人口、人均国内生产总值、土地面积和城市化水平之间的回归结果。它表明，电话、发电能力和铺设道路的存量往往随着人口的增加而成比例增加，而且与人均国内生产总值成比例地增加。公路总长度和铁路线总长度都随着国家的大小而增加，对人口和收入的影响相对较小。
This article describes an annual database of physical infrastructure stocks for a cross-section of 152 countries for 1950-95. The database includes estimates of six measures of infrastructure: the number of telephones, the number of telephone main lines, kilowatts of electricity-generating capacity, kilometers of total roads, kilometers of paved roads, and kilometers of railway lines. Both raw and manipulated data sets, in which series have been linked to overcome changes in definition and coverage, are reported. Some measures of infrastructure quality, such as the percentage of roads in poor condition, the percentage of local telephone calls that do not go through, the percentage of diesel locomotives available for use, and the percentage of electricity lost from the distribution system, are included. The data on all series except total roads are of reasonably good quality and should prove useful to researchers.The article also presents regression results relating stocks of infrastructure to population, per capita gross domestic product, land area, and level of urbanization. It shows that stocks of telephones, electricity-generating capacity, and paved roads tend to increase proportionately with population and more than proportionately with per capita gross domestic product. Both the length of total roads and the length of total rail lines rise with country size and are relatively insensitive to population and income.
