Resumo: The Literature Review that is presented here aims to bring theoretical considerations about the destruction of value. The co-destruction of value in the hotel industry in Portugal can occur for different reasons and in different contexts. As is the case with economic crises, political instability and changes in consumer preferences. To mitigate the destruction of value in the hotel industry, hotel owners and managers need to be aware of market trends, invest in maintenance, offer quality services, adopt effective marketing strategies and be prepared to adapt to changes in consumer preferences. and in the business environment. The term value destruction is considered recent in the literature and is a process of interaction between service systems that results in a decline in at least one of the welfare systems (which, given the nature of a service system, can be individual or organizational). The theme of value co-creation is consolidated from the discussions of Zikmund et al (2013), Meyer & Schwager (2015), Rajnish et al. (2017) and Mxunyelwa e Henama (2019) among other authors. These consider essential and extremely important the change in the role of customers, who are increasingly informed when making their purchasing decisions.The new dominant logic of services (LSD) changes the focus of attention when creating value for the customer, now not only in production, but mainly in relationships with customers.
