We examine the spillover effects of infrastructure on economic growth after controlling institutions and regional integration. We develop an augmented endogenous growth model to test the complementarity between proximate factors and infrastructure to explain regional growth dynamics. We build a multidimensional infrastructure index, capturing quantitative and qualitative dimensions using the Alkire-Foster method. The empirical analysis is based on 35 Asian economies during the 2006–2016 period using the spatial Durbin panel model. The results show that infrastructures have a positive and significant effect, both direct and spillover, on regional development. The quality of the infrastructure has a relatively higher direct impact, and the quantity has a relatively high spillover effect. These results show that the amount of infrastructure is more beneficial for the regions. On the contrary, quality is more fruitful for the country. Furthermore, the analysis confirms the complementarity of infrastructure with institutions and regional integration, which implies that these factors act as a stimulus to improve the spillover effects of the infrastructure. This analysis supports infrastructure development policies to achieve sustained economic growth in Asia. Infrastructure is a “big push” for these economies to improve their economic status and eliminate poverty. The complementarity of institutions and regional integration requires these factors to be considered in planning infrastructure development policies, particularly for economic corridors.

我们考察了在控制制度和区域一体化之后基础设施对经济增长的溢出效应。我们开发了一个增强的内生增长模型来测试邻近因素和基础设施之间的互补性，以解释区域增长动态。我们构建了一个多维基础设施指数，使用 Alkire-Foster 方法捕获定量和定性维度。实证分析基于 2006 年至 2016 年期间的 35 个亚洲经济体，使用空间杜宾面板模型。结果表明，基础设施对区域发展具有积极和显着的直接和外溢效应。基础设施的质量具有较高的直接影响，数量具有较高的溢出效应。这些结果表明，基础设施的数量对地区更有利。相反，质量对国家更有成效。此外，分析证实了基础设施与制度和区域一体化的互补性，这意味着这些因素可以作为改善基础设施溢出效应的刺激因素。该分析支持基础设施发展政策，以实现亚洲经济的持续增长。基础设施是这些经济体提高经济地位和消除贫困的“大推动力”。机构和区域一体化的互补性要求在规划基础设施发展政策时考虑这些因素，特别是经济走廊。此外，分析证实了基础设施与制度和区域一体化的互补性，这意味着这些因素可以作为改善基础设施溢出效应的刺激因素。该分析支持基础设施发展政策，以实现亚洲经济的持续增长。基础设施是这些经济体提高经济地位和消除贫困的“大推动力”。机构和区域一体化的互补性要求在规划基础设施发展政策时考虑这些因素，特别是经济走廊。此外，分析证实了基础设施与制度和区域一体化的互补性，这意味着这些因素可以作为改善基础设施溢出效应的刺激因素。该分析支持基础设施发展政策，以实现亚洲经济的持续增长。基础设施是这些经济体提高经济地位和消除贫困的“大推动力”。机构和区域一体化的互补性要求在规划基础设施发展政策时考虑这些因素，特别是经济走廊。该分析支持基础设施发展政策，以实现亚洲经济的持续增长。基础设施是这些经济体提高经济地位和消除贫困的“大推动力”。机构和区域一体化的互补性要求在规划基础设施发展政策时考虑这些因素，特别是经济走廊。该分析支持基础设施发展政策，以实现亚洲经济的持续增长。基础设施是这些经济体提高经济地位和消除贫困的“大推动力”。机构和区域一体化的互补性要求在规划基础设施发展政策时考虑这些因素，特别是经济走廊。
