This paper uses two longitudinal datasets—one with more limited coverage from the organization for economic co-operation and development and another constructed using general government gross fixed capital formation—to test for the relative effects of infrastructure versus non-infrastructure investment on output per worker, between developed and developing economies. The paper presents evidence that increasing infrastructure per worker has a larger relative impact on developing economies. This also implies that the share of gross capital formation devoted to infrastructure should be higher in developing economies.

基础设施投资对发达和发展中经济体的影响

本文使用两个纵向数据集——一个来自经济合作与发展组织的覆盖范围更有限，另一个使用广义政府固定资本形成总额构建——来测试基础设施与非基础设施投资对人均产出的相对影响, 发达经济体和发展中经济体之间。该论文提出的证据表明，增加人均基础设施对发展中经济体的相对影响更大。这也意味着用于基础设施的资本形成总额在发展中经济体中所占的份额应该更高。
