The topicality and necessity of the topic is motivated by the usefulness and necessity of approaching, from a new perspective, the development of the southeastern region of Romania through some important features in the increasingly challenging era of the prohibitions imposed by COVID 19, some knowledge which tries to answer the increasing complexity of economic and social realities, interactive and innovative approaches, analysis and promotion of the natural and anthropic potential of this tourist area and tourism enterprises, activities accomplished by them and attracting foreign investors, practices made public by managers in the tourism sector.

In order to improve the quality of the services in the tourism sector, by training / qualifying the staff, the customer orientation through some tourism promotion and information policy, the conservation and preservation of the sustainable environment, the visualization of managerial practices, methods of investigation, analysis, survey, questionnaire, observation, comparison, being completed more stages: documentation (consultation of representative works in the tourism sector), then the research of some empirical facts (practical reality data), fact which gives the whole approach the character of scientific work. Given the specificity of the data, the Spearman correlation coefficient and the Hi correlation coefficient (x ) were used to analyze the links and correlations between different items and different variables related to the sample, to validate the research hypotheses.
