Tourism represents one of the main industries in terms of job creation and economic development while sustainability in tourism represents a worldwide challenge. The objective of the present study is to use a bibliometric approach to review the relevant literature. Bibliometric indicators, such as citations, are used to identify the field structure and the VOSviewer software is used to map the main trends in this area. Over the period 1987–2018, a total of 4647 papers were found in Scopus regarding sustainability issues in tourism. Analysis of the leading journals, authors, institutions, and keywords indicates that: (1) the literature on sustainability issues in the field of tourism is significantly growing; (2) a mere six papers accounted more than 300 citations, but there are several prolific authors; (3) of the 614 sources included in the review, the most important have published 46.7% of the papers; (4) in terms of documents and citations, the United States is the leading country in this topic; (5) according to keyword trend network analysis, sustainability is becoming a strategic approach for companies and tourist destinations. Finally, this subfield within the tourism literature has considerable potential and is expected to continue growing.

Purpose: The aim of this research is two‐fold: to examine the effects of certain characteristics of top management teams (TMTs) on innovative performance in their companies; and to determine if this influence is direct or if it is influenced by other factors, such as the existence of strategic consensus in the team.Design/methodology/approach: The research is developed using Upper Echelon Theory. This study was conducted with a sample of 100 companies from innovative sectors. Different regression analysis were undertaken in order to test the established hypotheses.Findings: Three main conclusions can be drawn from this research. First, it cannot be stated that all types of diversity related to TMT activity or work have a positive effect on innovation in companies. In this way, diversity in TMT tenure appears to have a negative influence. Second, the incidence of diversity on innovation cannot be direct in all cases. Therefore, functional diversity has a positive effect on innovation, but always when there is a context of strategic consensus in the management team. Finally, TMT educational level exerts a positive effect on organizational innovation degree, independently on processes, which may occur within the team.Originality/value: The paper has tried to improve and clarify the contributions about the direct relationship model proposed by Upper Echelon Theory between TMT demographic characteristics and innovation. The results have confirmed, in support of the critics of the theory that it is necessary to introduce and analyze, along with demographic variables, other factors and processes which affect TMT decision making.
