Development and Evolution of Slacks‐Based Measure Models in Data Envelopment Analysis: A Comprehensive Review of the Literature

Journal of Economic Surveys, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 10, 2025

ABSTRACT This paper provides a comprehensive review of slacks‐based measure (SBM) models within the nonparametric data envelopment analysis (DEA) framework. The reveals that development and modifications SBM have progressed in multiple directions. Key areas modification include (1) nature inputs outputs, (2) specificity, (3) super‐efficiency for ranking decision‐making units, (4) inclusion networks organizational structures or production processes, (5) dynamic analysis, (6) various other methodological aspects. Increasingly, complex addressing aspects, such as input/output characteristics are appearing literature. Another notable trend is integration proposals from different authors into unified models. Some publications even attempt to forecast future efficiency levels incorporate large datasets (big data). Despite numerous advancements, still lack robust statistical inference capabilities, unlike radial models, which possess more developed foundations.

The efficient use of water must be enhanced and promoted to achieve the Sustainable Development Goal (SDG) 6. Thus, contribute achievement SDG Target 6.4 close a research gap in SDGs' progress, this paper carries out usage efficiency analysis 126 countries leveraging AQUASTAT database maintained by Food Agriculture Organization United Nations (FAO), providing information that can help assess promote sustainable management water. methodology uses conceptual model considers Water Withdrawal (WW) stage Productivity (WP) stage, each one with its own set variables, designing customised non-parametric frontier solution identifies best practices them as benchmarks for global usage. In particular, proposed approach non-radial Directional Distance Function (DDF) estimates inefficiency along different dimensions, both desirable undesirable, quantifying potential improvement computing an score whole system. Due heterogeneity sample, metafrontier has been carried out. results indicate there are significant differences between regions terms efficiency. highest include Australia, Western Central Europe Southern Eastern Asia, while Asia lowest. Most corresponds Gross Value Added dimension WW is generally higher than WP stage.

A novel method of assessing port resilience and its positive ramifications

Maritime Policy & Management, Journal Year: 2025, Volume and Issue: unknown, P. 1 - 24

Published: Jan. 19, 2025

Ports play a crucial role in facilitating global trade and logistics, serving as vital hubs that connect countries continents. However, they are susceptible to disruptions disasters due their natural characteristics, while resilience is essential for maintaining regular operations, especially the face of disruptions. From perspective inputs outputs, this study evaluates nine major Chinese ports from 2011 2021, using super-efficiency slacks-based measure network data envelopment analysis (SBM-NDEA). This approach extends beyond evaluating port's internal capacities, incorporating urban economic factors critical ensuring long-term resilience. The novel method assessing port its positive ramifications offers clearer understanding specific stages requiring improvement, thereby enhancing overall ports. Specifically, three considered: absorptive, adaptive, restorative. results reveal different exhibits distinct trends above stages. Shenzhen Port demonstrates superior performance both absorptive adaptive stages, Rizhao excels restorative stage. research contributes advancing academic knowledge industry practices by offering new insights, methodologies, practical implications

General network production theory for good and bad inputs and outputs

Journal of Productivity Analysis, Journal Year: 2025, Volume and Issue: unknown

Abstract The paper systematically extends a recently developed general production theory for networks of arbitrarily complex structure by utilising multi-criteria analysis to include undesirable objects as inputs and outputs. By embedding Koopmans’ linear activity into the broader framework approach is generic in that it requires rather weak technological properties, thus allowing non-convex even discrete possibilities without any disposability property. modelling can often be more appropriate than conventional ones easily extended dynamic analyses, since its network flow equations are based on balances integrate inventories cases material Theorems proved relate important properties whole (e.g. convexity) or their activities efficiency) those individual units.

Published: April 1, 2025

This study employs Data Envelopment Analysis (DEA) to evaluate the efficiency of top 20 smart cities in converting Research and Development (R&D) investments into desired outcomes. Using national R&D expenditure (2015–2022) as input ten criteria from IMD 2024 Smart City Index report outputs, analysis reveals varying levels among leading cities. Seven achieved perfect scores, while others, including some high-ranking cities, showed unexpected inefficiencies. provides valuable insights resource utilization identifies specific areas for improvement across structural technological dimensions. The limitations include focus on top-performing use data a proxy city-specific investments. findings this offer foundation policymakers urban planners optimize allocation improve city initiatives, contributing ongoing development sustainable environments face advancements challenges.
