摘要:Tourism is an activity, which has a heterogeneous treatment by scholars in this field. Current approaches prefer to focus on it from economic consideration in general or as a simple genesis of new contractual arrangements. The tendency to consider tourism as a matter of State requires then of a normative political effort and the implementation of basic criteria that would serve to consolidate it in this sense. Studies on tourism are relatively recent. While chemistry, medicine, mathematics and geography have been under review since the earliest times, this "pleasure" travel does not begin to be studied in a scientific manner until between the wars (1919-1939). During 1920s, the world lived a stage of economic boom. It was at this time when it was popularized the use of the telephone, automobile and home appliances as well as travel, because in these years, thanks to the increase of income per capita and a cheaper, a lot of people that before would not have been able to have access to tourism, had access to this privilege. This explains that the increased movement of people leaves more money in the visited places (receptors cores). The first effect arising from the massive influx of tourists to a place is therefore expenditure; hence the first studies were carried out from the world of economics. Tourism is defined as the set of relations and phenomena that occur as a result of displacement and temporary stay of persons outside their place of residence, provided that it is not motivated by lucrative reasons.
