Abstract

ABSTRACT This study analyses whether higher efficiency performance of Ecuadorian hospitals attracts larger inflows of interregional patients to a given hospital and assesses the existence of spatial dependence in the patient migration network. We develop an innovative two-stage approach. In the first stage, we use conditional order-m estimations to obtain robust hospital efficiency. In the second stage, we apply a spatial Durbin interaction model to estimate the effect of hospital efficiency on patient migration flows and disentangle the spillover effects. We identify the positive effect of specialized hospitals’ efficiency in attracting patients from other regions alongside spillover effects in the migration dyad.

患者迁移流的空间依赖性

摘要本研究分析了厄瓜多尔医院的高效率是否会吸引更多的区域间患者流入特定医院，并评估了患者迁移网络中是否存在空间依赖性。我们制定了一种创新的两阶段方法。在第一阶段，我们使用条件阶-m估计来获得稳健的医院效率。在第二阶段，我们应用空间Durbin交互模型来估计医院效率对患者迁移流的影响，并理清溢出效应。我们确定了专科医院在吸引其他地区患者方面的效率的积极影响，以及迁移二元中的溢出效应。

期刊介绍： Spatial Economic Analysis is a pioneering economics journal dedicated to the development of theory and methods in spatial economics, published by two of the world"s leading learned societies in the analysis of spatial economics, the Regional Studies Association and the British and Irish Section of the Regional Science Association International. A spatial perspective has become increasingly relevant to our understanding of economic phenomena, both on the global scale and at the scale of cities and regions. The growth in international trade, the opening up of emerging markets, the restructuring of the world economy along regional lines, and overall strategic and political significance of globalization, have re-emphasised the importance of geographical analysis.
