Small- and medium-sized enterprises (SMEs) generally make a crucial contribution to local and national economies. As the market has become increasingly globalised over the past two decades, SMEs often feel the need and/or push to internationalise their business activities. It is in this need that several barriers and challenges are perceived by SMEs, since these companies generally have different characteristics and resources compared to large multinational enterprises (MNEs). Accordingly, given that the literature on internationalisation is rather extensive and relatively fragmented, this study seeks to systematically understand the scientific structure of research on the internationalisation of SMEs, and how it is organised.

The authors used a bibliometric approach and data co-citation to identify and systematise the scientific publications, intellectual structures and research trends related to SME internationalisation.

The study research reveals five approaches that theoretically support the internationalisation processes of SMEs: (1) internationalisation and networks; (2) internationalisation and venture capital; (3) internationalisation and intrinsic characteristics; (4) internationalisation and transactional costs; and (5) internationalisation and firm resources and capabilities.

This study has important implications for academics and practitioners who are likely to benefit from a holistic understanding of the different aspects of SME internationalisation.

The aim of the study is to analyze how knowledge spillovers and knowledge management capabilities affect the innovation capabilities of hospitality sector companies in crisis environments.

A survey was completed by 63 hotel directors based in Portugal, gathering data on knowledge spillover, knowledge management capabilities and innovation capabilities. Two multiple linear regression models were used to estimate the impact of knowledge spillovers and knowledge management capabilities on innovative capability.

It has been concluded that knowledge spillovers work as external benefits of knowledge creation, increasing the innovation activities of companies in the hospitality sector, which reinforces that knowledge spillovers help to enhance innovation capabilities. The study's results show that it is essential for companies to manage knowledge. It also concludes that effective knowledge management facilitates the exchange of knowledge required in the innovation process. Knowledge spillovers improve the performance of innovation in companies through the development of new insights and innovation capabilities.

This research was carried out in a period of crisis. As expected in a troubled period, the results are extremely volatile. This study's sample is composed of Portuguese hospitality companies.

This research provides valuable insights into the overflow of explicit and tacit knowledge in the hotel industry. Moreover, this study offers new insights into the mediating role of knowledge management capability in the relationship between a hotel's knowledge overflow and its innovation performance.

Knowledge and its management and, more recently, strategic knowledge management (SKM) represent major challenges for the organisations of the 21st century. Despite the importance of this knowledge field, and the significant quantity of research that has focussed on this theme, there is a dearth of studies in the literature undertaking a systematic SKM review. This study aims to provide a currently complete and systematic SKM review to stimulate and contribute to furthering this academic field and correspondingly set out an agenda for future research.

This paper sourced the data from the science citation index expanded (SCI-expanded), the social sciences citation index (SSCI) and the arts and humanities citation index (A&H CI) databases. This research spanned references published in journals belonging to the categories of management, business and economics without any chronological filter. The search returned a total of 99 references with their dates of publication between 1995 (1 reference) and 2018 (7 references).

The results included the identification of three core approaches to this study field: SKM models and competitive advantage, SKM implementation and the Systematic SKM approach.

This current study seeks to undertake the mapping of the scientific publications, the intellectual structure and research trends in the SKM field to: identify the fundamental contributions to the SKM research field; determine the research pathways establishing its intellectual structure and the scientific journals with the greatest impact on the field and identify the SKM research field geographical distribution and its collaborative structure.

This study defines a roadmap for an informed research agenda that proposes multiple directions: the usage and development of an innovative theory that may open new paths for future research and theoretical construction; a more sophisticated understanding of the concept and its applicability; approaching the shortcomings interrelated with the content across different levels of analysis; and the application of relevant and appropriate methodologies for operationalizing SKM.

The purpose of this paper is to empirically examine the moderating effect of competitive advantage on the resource value and rareness combination and firm performance.

The authors adopted a quantitative research method to achieve the aims of this study. The data collected came from a sample of footwear firms and the hypotheses assessed by multivariate analysis.

The findings provide insights into previously inconsistent findings regarding the exploitation of resources and capabilities and contribute to resolving these issues by considering the conditions under which the resource value and rareness combination contributes to firm performance levels and the effects of competitive advantage on this relationship. Interestingly, the authors find that it cannot be inferred that the rarer the resources and capabilities combination, the greater the probability of attaining competitive advantage.

As limitations, the authors would highlight the fact that the results are specific to one particular industrial sector, and thus not susceptible to the drawing of generalisations as well as the fact that the study does not make recourse to triangulating its methodology (for example, through interviews), which would generate more precise, detailed and objective information. The findings have important managerial implications and the authors close by presenting future research directions.

This study offers an explanation for previous mixed findings on the relationship between the resource value and rareness combination and firm performance and makes a contribution regarding how such combinations are of great relevance to the organisation and business strategy to turn in better performance levels.

Research into the relationship between entrepreneurial ecosystems and sustainability has deepened in terms of both quantity and quality even while still remaining a fragmented and divergent field. Hence, the purpose of this study is to put forward empirical evidence to advance the literature on the relationship between entrepreneurial ecosystems and sustainability. To this end, the authors furthermore identify and highlight a future research agenda.

The source of the empirical analysis in this article stems from the Community Innovation Survey, the leading statistical inquiry of innovation in companies carried out by Eurostat based upon the conceptual framework set out in the Oslo Manual. For modelling the variables, the authors applied binary regression based on logistic distribution.

The results of the research demonstrated how all of the variables considered for entrepreneurial ecosystems (co-operation with suppliers, co-operation with clients or customers, co-operation with universities; co-operation with government, public or private research institutes) return positive impacts on national sustainability

Despite the data spanning only the nine countries in the database, the results enable insights into the theory as the results serve to strengthen already existing considerations on the positive effects of entrepreneurial ecosystems for the sustainability of countries.

The results of the research may generate important implications for company policy formulation. The identification of the relevance of the different actors in entrepreneurial ecosystems and their impact on sustainability may assist firms and policymakers to identify the leading actors and the resources necessary to sustaining their activities and thereby correspondingly establishing their priorities.

The research (1) both deepens the prevailing knowledge on this theme and fills a gap encountered in the existing literature; (2) in practical terms, for managers, entrepreneurs and politicians to better grasp how entrepreneurship constitutes a systemic phenomenon and these systems require approaching in terms of their impacts and greater contributions to obtaining sustainability.

This study aims to map scientific publications, intellectual structure and research trends in the development of human resource management (HRM) by adopting innovative practices. Specifically, it aims to (1) identify the fundamental contributions of research and to (2) determine the lines of research that constitute the most prominent intellectual structure to contribute to defining a future research agenda.

This study employs bibliometric, bibliographic coupling and cluster analysis techniques. To evaluate any potential patterns among the articles, it is analyzed how those were jointly cited. Hierarchical cluster analysis was also applied to those subject to bibliographic coupling analysis within the scope of grouping the interrelated articles into distinct sets.

The results enabled the identification and classification of various theoretical perspectives on human resources development through the adoption of innovative practices into four main approaches: (1) organizational factors of success, (2) strategic HRM, (3) human behavior and (4) learning management.

This study identifies, explores, analyzes and summarizes the main themes contributing to deepening the literature by identifying the priority areas concerning HRM through the adoption of innovative practices that can guarantee international standards of excellence.

There has been a diverse range of research on the factors enabling informal entrepreneurship as well as the means to avoid or to eradicate its incidence. However, the authors may also identify how a significant proportion of research on this field of study centres around developing economies and correspondingly justifying the application of such analysis to countries with different levels of economic development as is the case of Europe. The purpose of this paper is to depict the ways in which economic and political institutions influence informal entrepreneurship.

To this end, the authors apply aggregate data at the national level collected from different sources, in particular the World Bank, the Organisation for Economic Cooperation and Development, the Global Entrepreneurship Monitor and Freedom House, for the years between 2006 and 2015 and for 23 European countries amounting to a total of 229 observations (unbalanced panel).

Through recourse to econometric estimations, based upon multiple regression model methodologies for panel data, the authors may report that the greater the quality of economic and political institutions, the lower the level of informal entrepreneurship.

The authors thus seek to contribute towards a better understanding of the influence of institutions and the policies that may feasibly influence informal entrepreneurship.

The purpose of this paper is to present a conceptual framework for performance measurement (PM) for the integration of supply chain management (SCM) and quality management (QM).

A systematic literature review on SCM and QM was conducted to develop key performance measures related to six areas of integration between QM and SCM: leadership; continuous improvement and innovation; sustainability performance; stakeholders; information system; and management and strategic planning.

Supported by the literature concerning to supply chain quality management (SCQM) integration, a set of nine propositions about performance measures, that contribute to the integration of SCQM, were developed.

This study contributes to QM practices within a supply chain environment from an integrated perspective. Additionally, the propositions have significant implications from both managerial and theoretical perspectives. This study also extends the concept of supply chain quality integration by focusing on key aspects of PM that may help to improve the overall performance of the supply chain.

This paper aims to present and discuss an innovative maturity model (MM) to assess supply chain quality management (SCQM). The SCQM MM can be used to guide organizations in the development and improvement of quality in their supply chains (SCs). Additionally, this paper intends to better understand that integration and its impacts on organizational performance.

The proposed MM was developed based on an exhaustive literature review of the most relevant MMs developed in the areas of quality management, supply chain management and other relevant domains.

The proposed MM consists of a matrix with 100 criteria organized in five organizational dimensions and five maturity levels, embracing the most relevant SC issues and describing a progressive path towards a state of full maturity.

It is an innovative tool useful for both academic experts and practitioners to integrate quality management across the SC, thus promoting and improving organizational performance from an integrated and sustainable perspective.

This study aims to map scientific publications, intellectual structure and research trends in the sustainable business model (SBM) field. Specifically, it attempts to (1) identify the fundamental contributions of research in this area of knowledge; and (2) determine the research lines that constitute the most prominent intellectual structure. We leverage these insights to formulate and propose a future research agenda for SBM.

The authors made recourse to the bibliometric, co-citation and cluster analysis techniques. To evaluate potential patterns among articles, we analysed how articles are jointly cited. We further applied hierarchical cluster analysis to the articles and used co-citation analysis to group the interrelated articles into distinct sets.

The results enable the identification and classification of the prevailing theoretical foci in the domain of SBM: (1) SBM implementation; (2) SBM challenges; (3) institutional SBM; (4) circular SBM; and (5) emerging SBM.

This study identifies, explores, analyses and summarises the main theoretical approaches and themes surrounding SBM research to date, contributing to deepening the literature by identifying the priority areas concerning sustainable business models and encouraging future research of an internationally excellent standard.
