The research article in the field of tourism studies has not been sufficiently studied, despite being a discipline strongly connected with a sector of economic growth for many countries. Other textual genres related to the tourism register such as the summary, brochures and web pages in the tourism register, the latter with great relevance for their clear social and economic impact of tourism studies, have enjoyed more scholarly attention. Scientific research in tourism, however, provides organisations, whether public or private, with relevant information for the improvement of the activity, which translates into recommendations that are often included in the conclusions of these studies. It is held, therefore, that there is a direct relationship between the development of the sector and empirical research, which, in turn, shows the interest in academic publications in leading journal. For this reason, this paper includes a formal characterisation of the genre into sections. This study is supplemented with a description of the recurrent lexicalgrammatical structures in each of the sections of the scientific article and the lexical and syntactic variables that characterise the text within the scientific register, both in terms of the complexity and the level of elaboration exhibited in the language used in these works. These structures are intended to signal the authors' perspective, among other aspects.
