Air transportation is a paramount element within the transport infrastructure of any country. In recent years, several factors have led to an increased demand in the civil aviation industry in Brazil, putting pressure on the country’s airport infrastructure, which by itself justifies industry-related efficiency studies. Although the airport efficiency analysis is widely discussed in the literature, studies aiming to compare public and private Brazilian international airports are still scarce. The main objective of this study is to comparatively analyze the efficiency of public and private Brazilian international airports. To do so, efficiency was studied under two mathematical approaches: the two-stage DEA model and the Malmquist Index. Subsequent statistical analyses show a significant difference in efficiency between government-managed airports and those under concession to the private sector.

巴西公共和私人国际机场的基础设施和航班整合效率：两阶段DEA和Malmquist指数方法

空中运输在任何国家的运输基础设施中都是至关重要的。近年来，一些因素导致巴西民航业的需求增加，给该国的机场基础设施带来了压力，这本身就证明了与行业相关的效率研究的合理性。尽管文献中对机场效率分析进行了广泛讨论，但仍缺乏旨在比较巴西的国际和私人国际机场的研究。这项研究的主要目的是比较分析巴西公共和私人国际机场的效率。为此，通过两种数学方法研究了效率：两阶段DEA模型和​​Malmquist指数。
