Purpose: For better mapping the path of intellectual capital (IC) research, the purpose of this paper is to selectively review empirical studies of IC published, and identify theories, components and three dimensions of analysis: national IC (NIC), regional IC (RIC) and organizational IC (OIC). Design/methodology/approach: The systematic literature review (SLR) subject to analysis is based on empirical studies made between 1960 and 2016, and focuses on three dimensions of analysis: NIC, RIC and OIC. Four research questions were designed, using the following databases, namely, Web of Science, Scopus and Google Scholar, for data collection purposes. Findings: The SLR unveils a multidimensional taxonomy for measuring and classifying the type of IC applicable to the different levels of analysis and provides some recommendations for future studies of NIC, RIC and OIC, by outlining the need for clear definitions of components and measures of IC and identifying strengths, limitations and future research avenues. Originality/value: In order to fill the gap found in the literature and the non-existence of a study clarifying the multiple dimensions of analysis of IC, this SLR makes a twofold, original contribution to the literature on management: providing an SLR of the main empirical studies dealing with different units of analysis; and identifying a multidimensional taxonomy for measuring and classifying the type of IC applicable to the different levels of analysis.

Purpose: The purpose of this paper is to determine the predominant classification of intellectual capital (IC), in terms of components, using the literature of reference on the relationship between IC and performance and considering multi-dimensional analysis axes (MAAs): organisational, regional and national. Design/methodology/approach: A systematic literature review (SLR) is presented focussing on empirical studies on IC published in the period 1960-2016. A protocol for action is defined and a research question is raised, gathering data from the databases of: Web of Science, Scopus and Google Scholar. A social network analysis is also provided to determine the type of networks embracing groups, IC individual components and performance type. Findings: Of the 777 papers included in the SLR, 189 deal with the relationship between IC and performance. The paper highlights the greater development of empirical studies starting from 2004; the organisational MAA is the most studied. The most frequently used groups of components in studies dealing with IC’s influence on performance corresponds to a triad of human capital; structural (organisational or process) capital; and relational (social or customer) capital, which determine positively the performance of organisations/regions/countries, but their influence is not linear and depends on various factors associated with the context and surrounding environment. Practical implications: This study has wide-ranging implications for politicians/governments, managers and academics, providing empirical evidence about the relationships between the components of IC and performance, by MAAs, and a global vision and better understanding of how those IC components have developed and how they are related to performance. Originality/value: Due to the high number of references covering a wide range of disciplines and the various dimensions (e.g. organisational, regional and national) that form IC, it becomes fundamental to carry out an SRL and systematise its MAAs to deepen knowledge about what has been discovered/developed in this domain, in terms of empirical studies, in order to situate the topic in a wider theoretical-practical context. The paper is exceptionally wide-ranging, covering the period 1960-2016. It is one of the first clarifying studies on systemisation of the literature on IC, by MAA, and an in-depth study of IC’s impact on the performance of organisations/regions and countries which may serve as a guideline for future studies using the taxonomy proposed.

This paper analyses the relationship between the intellectual capital of higher education institutions (HEIs) and their sustainable development practices, and assesses whether higher education institutions’ sustainable development practices are related to their stakeholders’ quality of life. Using a structural equation model, two model specifications are estimated, gathering primary data from a convenience sample composed of 738 full-time students and 587 teachers/researchers at seven Portuguese higher education institutions. The findings reveal that intellectual capital influences sustainable development practices directly and positively, whereas sustainable development practices influence students’ quality of life in a significant way, although the same is not verified for teachers/researchers. These findings provide insightful implications for policy-making and intellectual capital management for practices in higher education institutions; firstly, by showing that the sustainable development concept is associated with HEIs’ practices of economic, environmental, social and organisational sustainability; secondly, by concluding that public Portuguese HEIs need to improve the social dimension of their sustainable development practices, and here there may be room for improvement in the institution through better and more proficient social engagement that is more directed to the challenges of sustainability and social change; and thirdly, by showing that the inclusion of better sustainable practices has repercussions on the quality of life of all stakeholders.

Purpose: The purpose of this paper is to present an innovative operational proposal for measuring the intellectual capital (IC) of higher education institutions (HEIs) through a strategic prospective lens of analysis.Design/methodology/approach: After providing a literature review on the methods for measuring IC that focuses on the organisational IC of HEIs, four case studies applied to Portuguese HEIs are presented, using a matrix of cross-referenced impacts – multiplications applied to a classification (MICMAC) approach.Findings: The empirical findings reveal how human capital, structural capital and relational capital make up the core components and provide a fairly diversified list of the measurement indicators for the operational evaluation of the IC of HEIs.Practical implications: It contributes into the literature of strategic prospective analysis of HEIs by: analysing the measurement systems for the organisational IC interrelated with HEIs; identifying the key components to the organisational IC of HEIs and their respective measurement indicators; and draufting a new method for operationally implementing organisational IC through the systematic application of the components and indicators identified.Originality/value: Through an innovative vision, the present study reconciles and systematically structures the methods already proposed by other authors before presenting an innovative operational approach and an alternative to the already existing methods. In addition, the structure of this proposal itself enables HEIs to choose from among the various indicators proposed for IC, correspondingly those that best align with the type of institution under evaluation.

This study explores the contributions of different dimensions of the intellectual capital of higher education institutions (ICHEIs) to their performance, incorporating the previously unexplored dimension of quality of life (QoL) as a performance measure, and correspondingly taking into account the connection between the Theory of Stakeholders and the Theory of Legitimacy. Applying a Structural Equation Model and the Partial Least Squares method, we present new empirical findings from a sample of 738 students and 587 lecturers/researchers from seven Portuguese public HEIs. The ICHEIs positively influence the institution’s performance, through relational capital and structural capital; and QoL emerges as an important dimension of HEIs’ performance standards, especially regarding students’ perception of academic QoL. When HEIs understand and measure their IC, they will gain a better understanding of their core competencies, enabling a better allocation of resources and implementation of more effective strategic and operational actions.

Purpose: This study aims to identify stakeholders’ perceptions of the effects associated with different components of intellectual capital (IC) on the sustainable development (SD) practices of higher education institutions (HEIs). Design/methodology/approach: The empirical approach uses a structural equation model to provide new empirical findings in relation to 738 students and 587 lecturers/researchers at seven Portuguese state HEIs through quantitative research. Findings: The results obtained are, firstly, important contributions to the literature on the IC and SD practices of HEIs, as a relationship between these two constructs is confirmed, especially through relational capital (RC) and structural capital (SC). Secondly, the stakeholders considered show different perceptions of the influence of the components of HEIs’ IC on these institutions’ SD practices, and thirdly, perception of the economic dimension is most influenced. Practical implications: The empirical findings indicate the need to provide better information about HEIs’ policies and practices of SD and how the latter contribute to the SD of the institution and its region of influence. Originality/value: No previous studies investigate students and teachers/researchers’ perceptions of the social, environmental, economic and organizational dimensions of SD in HEIs and at the same time how those perceptions can be influenced by the components of IC (e.g. human capital, SC, RC) in that institution.
