Logistics

Background: nowadays, traditional delivery options are challenging to the urban last-mile logistics and sustainability goals. The purpose of this study is to investigate the practical factors that drive frequent e-shoppers to actively switch their intention from conventional delivery options to utilizing smart lockers. Methods: the hypothetical framework tested integrating constructs from the Technology Acceptance Model (TAM) and the Theory of Planned Behavior (TPB), and supplementary constructs such as privacy and convenience. Data were collected via a structured online questionnaire from 513 respondents in major Egyptian cities, including Alexandria and Cairo. The framework was tested using Structural Equation Modeling (SEM) via SmartPLS 4.0 software to assess the relationship between constructs and switching intention. Results: the analysis confirms that switching intention to use smart lockers is positively driven by Perceived Usefulness, Perceived Ease of Use, Convenience, Privacy, and Perceived Behavioral Control. Notably, a positive attitude towards smart lockers was found to have a non-significant effect on the intention to switch in the Egyptian context. Conclusions: this research contributes to addressing the gap in the extant literature by focusing on analyzing the unique contextual determinants in the emerging last-mile logistics within a developing market context.

Background: This study examines how Green Knowledge Integration Capability (GKIC) influences supplier performance within sustainable supply chains by balancing exploration (acquiring new knowledge) and exploitation (refining existing knowledge) strategies. Methods: Based on Social Exchange Theory, Relationship Motivation Theory, and Absorptive Capacity Theory, a conceptual model was developed and tested using cross-sectional survey data collected from 398 managers representing 240 multinational corporations (MNCs) operating in Pakistan. Structural Equation Modelling (SEM) was employed to analyse the relationships among exploration and exploitation focus, Green Management Innovation (GMI), GKIC, Green Absorptive Capacity (GAC), and supplier performance. Results: The findings indicate that exploration and exploitation strategies significantly enhance supplier performance, with GKIC acting as a mediating mechanism linking strategic focus and innovation to performance outcomes. Moreover, GAC strengthens the impact of the exploration and exploitation focus on performance but exhibits limited moderating effects for GMI and GKIC pathways. Conclusions: The results highlight GKIC’s critical role in translating strategic and innovation initiatives into supplier performance gains. This study contributes to the sustainable supply chain literature and provides actionable insights for managers and policymakers to enhance sustainability outcomes through knowledge integration and absorptive capacity development.

Background: This study aims to examine the barriers hindering the implementation of sustainable procurement in Indonesian small and medium-sized enterprises (SMEs) and to identify their hierarchical relationships. Methods: A mixed-method approach was adopted, employing Interpretive Structural Modeling (ISM) to map the causal structure of barriers and Fuzzy MICMAC analysis to classify them according to their influence and dependence. Data were collected through expert evaluations and secondary sources, providing both empirical depth and contextual validity. Results: The results reveal that financial constraints, particularly funding limitations, are the most critical and independent barrier driving the entire system of obstacles. The analysis further shows that systemic linkage barriers, such as minimal government incentives, limited availability of eco-friendly raw materials, and high import dependency, create a self-reinforcing cycle that amplifies cost challenges for SMEs. Dependent barriers, including regulatory inadequacies and weak supplier collaboration, are identified as outcomes of these structural constraints, while autonomous barriers like limited consumer awareness remain less influential but still significant. Conclusions: These findings demonstrate that sustainable procurement barriers are not isolated but interconnected, with financial viability acting as the foundational challenge. The study contributes to the literature by providing a relational perspective on sustainable procurement barriers, offering managerial insights for policy.
