Abstract
Purpose
Inaccurate capturing and processing of customer requirements result in negative economic and ecological effects. Digital twins of customer demands promise to remedy these issues. However, successful implementation necessitates users' technology acceptance. This study contrasts three hierarchical digital twin levels with different degrees of user integration and examines determinants for their respective acceptance.
Design/methodology/approach
A structural equation model is applied in a comparative manner, considering different levels of digital twin radicalness. A multidimensional approach is used to measure attitudes towards usage. Data are collected in the context of organisational supply management.
Findings
Results show harmonious effects across digital twin levels. This indicates that technological radicality plays only a subordinate role when assessing acceptance determinants such as user perception on ease of use, usefulness, trust and risk.
Practical implications
Rather than focussing solely on technological factors, findings suggest that users prioritise the actual outcome and efficiency of the system. This perspective offers practical implications for organisations seeking to implement advanced systems and emphasises the significance of user perceptions beyond technological features.
Social implications
The societal impact of this research are an appreciation of customer roles in the supply chain where an enhanced detection of customer needs and preferences aligns businesses with the dynamic and evolving demands of a diverse and a continuously environmentally-conscious consumer base.
Originality/value
This study applies a measurement model for technology acceptance in a unique and multidimensional manner. Thereby, a comparative analysis of user perceptions across different digital twin levels sheds more light on a nascent, promising and underexplored technological method. This interdisciplinary research combined knowledge from the supply chain management and management information systems fields by highlighting key factors for the adoption of complex technological methods.

Abstract
Purpose
The purpose of this study is to provide a comprehensive bibliometric analysis of publications in the Journal of Public Procurement (JoPP) from 2001 to 2021. The study provides insights into trends in publications, prominent publication themes, influential authors, institutions and countries that have prominently been associated with the journal’s journey.
Design/methodology/approach
The study used a bibliometric and content analysis approach using the VOSviewer software to develop insights into the trends, structures and patterns in publications in the journal. Data for the study was extracted from the Scopus and Google Scholar databases.
Findings
The study established that there has been consistent growth in the number of papers published by the journal within the last two decades. Yearly average publication by the journal stood at 14 papers between 2002 and 2009, with the annual average rising to approximately 18 papers between 2010 and 2021. The trend in publication has been established and identified the influential citations and contributors to the journal. The study has also clustered out the thematic structures in journal’s publications. The prominent and emerging research issues in the public procurement environment needing immediate research attention have been highlighted.
Research limitations/implications
The study is a one-journal bibliometric analysis and subsequently ignores publications on public procurement from other journals.
Social implications
The findings of this study highlight to the research community the contributions of JoPP to the public procurement discourse and present important avenues for future research agenda.
Originality/value
To the best of the authors’ knowledge, this study is the first bibliometric study for the JoPP, providing detailed bibliometric indexes of the 21-year period of the journal’s publications. The study comprehensively analyses the contributions in the JoPP to assess the trend and scope in publications in the field of public procurement and draws attention to emerging concerns and critical issues of neglect requiring research attention in the journal.
