PurposeThis paper attempts to seek answers to four questions. Two of these questions have been borrowed (but adapted) from the work of Defee et al.: RQ1. To what extent is theory used in purchasing and supply chain management (P&SCM) research? RQ2. What are the prevalent theories to be found in P&SCM research? Following on from these questions an additional question is posed: RQ3. Are theory‐based papers more highly cited than papers with no theoretical foundation? Finally, drawing on the work of Harland et al., the authors have added a fourth question: RQ4. To what extent does P&SCM meet the tests of coherence, breadth and depth, and quality necessary to make it a scientific discipline?Design/methodology/approachA systematic literature review was conducted in accordance with the model outlined by Tranfield et al. for three journals within the field of “purchasing and supply chain management”. In total 1,113 articles were reviewed. In addition a citation analysis was completed covering 806 articles in total.FindingsThe headline features from the results suggest that nearly a decade‐and‐a‐half on from its development, the field still lacks coherence. There is the absence of theory in much of the work and although theory‐based articles achieved on average a higher number of citations than non‐theoretical papers, there is no obvious contender as an emergent paradigm for the discipline. Furthermore, it is evident that P&SCM does not meet Fabian's test necessary to make it a scientific discipline and is still some way from being a normal science.Research limitations/implicationsThis study would have benefited from the analysis of further journals, however the analysis of 1,113 articles from three leading journals in the field of P&SCM was deemed sufficient in scope. In addition, a further significant line of enquiry to follow is the rigour vs relevance debate.Practical implicationsThis article is of interest to both an academic and practitioner audience as it highlights the use theories in P&SCM. Furthermore, this article raises a number of important questions. Should research in this area draw more heavily on theory and if so which theories are appropriate?Social implicationsThe broader social implications relate to the discussion of how a scientific discipline develops and builds on the work of Fabian and Amundson.Originality/valueThe data set for this study is significant and builds on a number of previous literature reviews. This review is both greater in scope than previous reviews and is broader in its subject focus. In addition, the citation analysis (not previously conducted in any of the reviews) and statistical test highlights that theory‐based articles are more highly cited than non‐theoretically based papers. This could indicate that researchers are attempting to build on one another's work.

Although sustainable supply chain management (SSCM) has recently received increasing attention among UK manufacturing firms, there is a concern as to whether SSCM practices are being implemented because they are profitable or only because of governance coercive pressure. Thus, the aims of this paper are twofold: first, determining the role of governance in the adoption of SSCM practices; second, investigating whether SSCM practices can be both environmentally beneficial and commercially viable. In light of these issues, this paper develops and empirically assesses an integrated model of governance pressures-SSCM practices-performance. Data was collected from 146 UK manufacturing managers, and analysed using the structural equation modelling method. Exogenous driving forces of governance were found to be precursors to the successful implementation of SSCM practices. The empirical results further suggest that while the implementation of sustainable supply chain management has a positive effect on environmental performance, it does not necessarily lead to improved economic performance, as only sustainable procurement was found to have a positive effect on economic performance. This paper contributes to the literature by highlighting the role of governance in SSCM adoption and performance gains in environmental protection while economic performance is partially compromised. The results also provide useful insights for both managers seeking to adopt sustainable practices and policy-makers seeking to further promote sustainable supply chain.

This paper reports the findings of a two-year EPSRC funded research project into relationship and performance strategies in power regimes. The findings from 12 very different industrial and service sector cases studies demonstrate that there is a correlation between the ability to improve the performance of suppliers and the power circumstances that exist between the buyers and suppliers. Buyers appear to be able to achieve improved performance from suppliers in situations of buyer dominance or interdependence. The research also demonstrates that whatever the objective power circumstance managers often subjectively misperceive the appropriate sourcing choices available to them. As a result business relationships can be aligned, but they are often misaligned. Furthermore, misaligned relationships may be "remediable" but they may not.
