What the literature leaves open

  • The study identifies the challenge of constructing a multi-layer network framework to examine the spatiotemporal evolution of the HSR network structure and its correlation with the regional economic network. The study also identifies the challenge of applying the Mantel test and the Time Exponential Random Graph Model to confirm the correlation and verify the dynamic evolution mechanisms. The study notes the difficulty in directly obtaining economic data and the need to use the gravity model to construct the economic network.

  • Prior studies have predominantly focused on national-level networks or economically developed regions. There is a lack of research on urban agglomerations in underdeveloped areas of western China. The study aims to fill this gap by exploring the development characteristics of the HSR network and its internal relationship with regional economic development in Western China.

  • Several limitations should be considered when interpreting the findings of this research. First, the study was conducted at two specific airports in Turkey (one regional and one major global hub), which may limit the generalizability of the results to larger international hubs with different infrastructure. Second, the cross- sectional design captures passenger needs at a single point in time, potentially missing seasonal variations in health-related travel behaviors. Third, the data rely on self-reported measures, which are susceptible to recall bias and social desirability. Additionally, security constraints in sterile zones prevented objective observation of medical events, necessitating a reliance on participant declaration. Finally, while qualitative inter-coder reliability was high, the depth of thematic insights was constrained by the brief nature of open-ended survey responses.
