Liquidity Risk, Credit Growth and Bank Profitability in Vietnam: The Moderating Role of Bank Size

This study of Vietnamese banks from 2015 to 2023 reveals that while liquidity management and bank size directly enhance profitability, the impact of credit growth is contingent on bank size, with larger banks better able to leverage credit expansion for profits due to superior risk management capabilities, whereas smaller banks face greater vulnerability to aggressive lending.

Shocks, Reforms, and Infrastructure Investment in Turkish Rail Freight: Interrupted Time Series and Bayesian Counterfactual Evidence, 2000–2024

This study utilizes interrupted time series and Bayesian counterfactual analyses of Turkish rail freight data from 2000 to 2024 to reveal that high-speed rail openings and liberalization reforms failed to increase traffic, while the sector unexpectedly grew during the pandemic but suffered a severe, disaster-driven contraction following the 2023 earthquakes, challenging infrastructure-led optimism and highlighting the need for resilient network planning.

Patent Citation Networks Anticipate Technology Lock-In Risk: Multimodal Evidence from China’s Semiconductor Industry

This study demonstrates that patent citation-network structures can effectively anticipate technology lock-in risks in China's semiconductor industry before conventional performance indicators deteriorate, enabling the development of a Technology Lock-in Risk Index (TLRI) that serves as an early-warning screening tool, particularly for large patenting entities.

Discipline-Level Benchmarking of University Innovation Contributions in a Cross-Border Regional Innovation System: Evidence from the Guangdong-Hong Kong-Macao Greater Bay Area

This paper employs a novel discipline-level benchmarking framework to reveal that Hong Kong's research universities within the Greater Bay Area exhibit a structural bifurcation where high research excellence and networking fail to translate into cross-border commercialization due to pathway-dependent disciplinary configurations and a lack of feedback loops between societal engagement and competitive research capacity.
