Abstract

Public service delivery has become a key domain through which administrative law responds to contemporary challenges of governance, digitalization, and rising citizen expectations. However, existing scholarship has largely examined administrative law and public service delivery in isolation, leaving a gap in understanding how legal frameworks shape service outcomes in practice. This study addresses that gap by conceptualizing public service delivery as a functional site for analyzing administrative law and by identifying enforceability as a central explanatory variable. The article examines how administrative law shapes public service delivery through a comparative analysis of the European Union and Vietnam, focusing on legal principles, institutional arrangements, and governance mechanisms. Methodologically, it adopts a qualitative, law-centered comparative approach grounded in doctrinal analysis and structured through a thematic analytical framework. The analysis demonstrates that public service delivery in the European Union is embedded within a dense and enforceable administrative law framework, where legal principles, multi-level governance, and safeguards for digital administration enhance accountability, procedural fairness, and service quality. In contrast, Vietnam’s public service governance remains largely policy-driven. Although administrative law principles are formally recognized, their practical impact is constrained by limited judicial enforceability, particularly in digital and decentralized contexts. The study concludes that the decisive factor shaping public service delivery is not the formal recognition of administrative law principles, but their enforceability. Sustainable improvements therefore depend on consolidating administrative law as a rights-based and enforceable framework capable of aligning efficiency, digital innovation, and citizen-centric governance across diverse systems

Abstract

Digital technology enhances labor productivity by automating repetitive tasks and improving data-driven decision-making, while simultaneously increasing energy management efficiency through smart monitoring and optimization systems. Therefore, this study examines the impact of advanced digital technology (proxied by internet penetration) on labor productivity and energy management efficiency in Vietnam using ARDL analysis of annual data from 1990 to 2024. The model includes internet penetration, GDP per person employed (labor productivity), renewable energy consumption, and GDP growth. ADF and PP tests confirm a mixed order of integration, I (0)/I (1), justifying the use of ARDL bounds testing. Descriptive analysis indicates rapid digitalization, with internet penetration increasing from 0% to 84.15%, alongside steady productivity growth, while renewable energy consumption exhibits a strong negative correlation with the time trend (r = -0.9855), suggesting a declining pattern. ARDL results reveal very high persistence in labor productivity (lagged coefficient = 0.9929, p < 0.001). GDP growth exerts significant short-run effects, whereas internet penetration shows a delayed impact, with an insignificant contemporaneous coefficient but a positive lagged effect. Long-run estimates suggest continued productivity momentum and positive contributions from digitalization and macroeconomic growth. However, the error correction term is positive and statistically insignificant (0.1681, p = 0.597), indicating the absence of a stable long-run equilibrium relationship. Diagnostic tests confirm residual normality and homoscedasticity, while the Durbin–Watson statistic (1.5403) suggests mild positive autocorrelation. Overall, the findings highlight delayed productivity gains from digital infrastructure, emphasizing the need for complementary institutional and structural adjustments.
