This study evaluates bibliometric analysis of sustainable tourism in the open innovation realm, depicts emerging themes, and offers critical discussion for theory development and further research. Through the use of bibliometrix, this paper investigates the amount of studies conducted in this area and verifies if such studies have represented a contribution to the evolving research in the field of sustainable tourism. Specifically, the paper identifies whether and to what extent scholars have explored these interconnections and maps to get to a conceptual structure of the field under investigation. The results identify the development status and the leading trends in terms of impact, main journals, papers, topics, authors, and countries. The analysis and the graphical presentations are crucial, as they can help both researchers and practitioners to better understand the state of the art of sustainable tourism in the experiential and digital era.

This paper investigates the main elements that can influence customer satisfaction in tourist services, with specific reference to tourism industry. The importance of this topic resides in the fact that tourists’ positive experiences of service, products, and other resources provided by tourism destinations can produce customer retention as well as positive word-of-mouth. Indeed, satisfaction with travel experiences contributes to destination loyalty. The degree of tourists’ loyalty to a destination is reflected in their intentions to revisit the destination and in their recommendations to others. Thus, information about tourists’ loyalty is important to destination marketers and managers in order to sustain destination attractiveness. Although predominant literature has adopted a demand-side perspective, this paper analyses tourist satisfaction according to an overlapping perspective that contemplates both the demand and the offer side where this latter, in the wider meaning, also includes the systemic perspective. More precisely, this paper aims to identify the principle competitive strategies that the variety of stakeholders, cooperating together in a destination, has to implement in order to increase tourist satisfaction and loyalty. Indeed, the point of view of this paper is to understand how destination attributes and services affect the tourist satisfaction. In order to study the link between destination attributes and tourist satisfaction, the paper collects cross-sectional data via questionnaire, from May 2012 to May 2013. The adopted approach allows to individuate the factors that can influence tourist satisfaction, their (positive or negative) direction and their magnitude. This paper uses 14 tourist satisfaction indicators in order to measure the global satisfaction. Furthermore, this study allows to identify the current strengths and weaknesses of the tourist offer. In particular, the study paid attention to the phase of service delivery since it is the time when customer satisfaction is generated. From this study, it comes out that tourist satisfaction depends on a complex process where the role of each actor is fundamental and it must be in tune with all the other ones. Findings show that tourists visiting Naples are not completely satisfied, supporting that Naples has not a clear destination image.

Over the years, literature on the topic of destination resilience has gained increasing attention in different fields (strategic management; sociology; etc.). Therefore, the potentiality of resilience in the tourism field has stimulated the definition and the implementation of strategies, policies, and activities addressed to mitigate risks and seize opportunities through open innovation attitudes in times of crisis. This work aims to contribute to the debate on tourist destination resilience by proposing a conceptual framework of destination resilience and open innovation based on a bibliometric analysis. Moreover, this article is intended as a starting point for a wider discussion of factors that contribute to destination resilience and therefore provides the basis to develop a toolkit of matrixes and approaches. Findings reveal that resilience assessment, as well as in terms of performance, remain undiscovered. Moreover, the present research poses some unresolved questions, shaping interesting future research directions.

Increased awareness about the importance of a safe, healthy nutrition has changed human interactions with food and increased worldwide demand for high quality and ethical food. In this respect, the purpose of this paper is to highlight the concept of ethical food and the nature of kosher food production, assessing common traits and the main differences between the two. A literature review was undertaken in order to verify the direction in which further studies might proceed. A research review on current literature was carried out exploring concepts of ethical food and food certification underpinning kosher businesses by means of an analysis of both producers’ and consumers’ perspectives. In order to proceed with an accurate analysis, the paper matches both the conceptual analysis and the bibliometric one. The overlap between these two forms of analysis makes results robust and useful for future research. This review reveals common points between ethical and kosher food because attention is given to both processes and products and the way the market perceives them as expressions of trustworthy and safe production. Furthermore, the analysis reveals an under emphasis on kosher food in the academic world and the results reveal the importance of empirical analysis. The analysis is focused mainly on kosher food production as an expression of ethical food. It would be interesting, however, to expand the analysis to other types of ethical certification such as Halal food, for example, in order to perform comparative evaluations. From a practical point of view, it is interesting to note that kosher food is conceived as very safe food and that non-religious people are sensitive to this, which opens new horizons for ethical food. It also offers the possibility that firms that have never considered entering the field of ethical food certification may do so to expand their businesses. This implication also reveals that there is a higher attention on sustainability and safety in agro-food market. Therefore there are great opportunities of expansion for ethical food. From a social point of view, this paper is of importance for several reasons. It deals with a relatively new and relatively unexplored issue; it points out the relevance of sustainability and safety in food market and consumer behavior, it presents the possibility of exploring knowledge interactions between different perspectives (multidisciplinary approach) and cultures which, in the opinion, will present significant challenge in relation to agro-food business research in the future. The originality of this work is that of systematizing a literature review of ethical food, enlarging its scope and boundaries with specific reference to kosher food. It also highlights the need to focus on both management and marketing, since up to now there has been a lack of academic contributions to these areas of research. Directions for further research are outlined.

Purpose: Over the past few years, several scholars have focused on innovation strategies with specific regard to family food firms. In line with this research stream, the purpose of this paper is to understand how family food firms with long-standing traditions can implement innovative productions while remaining anchored to the past. Design/methodology/approach: By adopting a qualitative research methodology, mainly based on a multiple case study, this paper seeks to cover some unexplored areas regarding the opportunity of combining tradition and innovation to achieve success in the highly competitive international arena in which family food firms operate. The authors analyze the cases of “La Torrente,” “Cioccolatitaliani” and “La Fabbrica della Pasta di Gragnano.” Findings: Successful family food firms leverage their deep-rooted knowledge of both family and local traditions to innovate. At same time, they establish continuous info exchange flows with all of the firm’s stakeholders by adopting an open innovation approach. Research limitations/implications: From a theoretical perspective, there is a need for an in-depth study of how an effective blend of tradition and innovation is formalized, above all, in family firms. As for the practical implications, all the three case studies represent a best practice, especially for family firms with a long-standing history and strong local connections. Practical implications: The paper shows how important it is to keep traditional factors in food industry and offers hints and suggestions to decision makers of family firms on how to valorize, in terms of competitiveness, their traditional resources – almost bound to their territory with innovation tools and processes. Social implications: The paper is interesting because it offers an analysis of a specific group of firms – family firms – that characterize many industries in Italy and in Europe. Although often small, these firms can show dynamism and creativity. The paper offers hints on how to approach innovation in the sector while keeping the value of tradition. Originality/value: The originality of the proposed conceptual model stems from the need to overcome the previous theoretical models, which deal separately with sources of past knowledge and sources of new and/or external knowledge.

In recent years, the air transport sector has played a significant role in the economy of the areas served. The demand for air travel has doubled every fifteen years and has grown faster with respect to other industries. This is also due to the introduction of low-cost airlines (LCA). In the coming decades, more efficient management of airports will become an essential aspect to address. A clear understanding of the current airport structure based on the analysis of the operational efficiency will therefore be necessary. All air carriers seek to expand their operations at airports, which tend to operate efficiently in order to reduce costs. However, in carrying out their activities and maximizing operational efficiency, airports should simultaneously manage to increase their passengers’ satisfaction. All over the world, passengers are demanding higher levels of service and regulators are paying increasing attention to the provision of airport services and the quality of the services supplied. Starting from these considerations, the aim of this paper is to study the efficiency of an airport through joint analysis of the operational efficiency (with the Data Envelopment Analysis -DEA-model) for the airport manager (by maximizing the exploitation of existing infrastructures), taking into consideration the quality of airport services as perceived by the user. The original and added value of this work lies in the quantitative analysis of the main characteristics that determine the efficiency of main European airports, also taking into account the quality perceived by the users during their trips with the air mode. Thus, the efficiency of 103 European airports in 37 different countries, for the year 2018, were compared, highlighting the effect of low-cost airlines. This aspect, as far as the authors know, has not been treated in the literature. Indeed, this study represents a decision support system (DSS) tool for operational managers in the air sector for the identification of the characteristics that improve airport efficiency. This paper refers to the pre-COVID-19 period because it would not be useful to make an efficiency analysis influenced by the pandemic, since the latter represents a specific event. Therefore, this analysis provides interesting inputs for both researchers and practitioners to manage the issue of efficiency in ordinary contexts. Moreover, the airline industry is characterized by cut-throat competition, and it may be very useful in the close future to examine this issue to improve firms’ management in the industry.
