In a world marked by globalization, governments increasingly recognize entrepreneurship as a driving force for economic development and change. On the other hand, entrepreneurship is a fundamental component of the knowledge economy because the potential value of new ideas from research and knowledge can be best exploited by SMEs, rather than economic structures of production of table processes and markets relatively unknown. Travel and tourism activity are no exception, they have become today, a task as important as that done in industry, agriculture and trade. Tourist phenomena are becoming more complex and difficult to address the scientifically because, like any human activity, they fall under the influence of interdisciplinary study, involving economists, geographers, psychologists and sociologists. The issue aims at evaluating various types of entrepreneurship in rural communities adjacent to protected areas and produce an analysis of the extent to which business entrepreneurship for rural tourism and ecotourism is a prerequisite for sustainability equally protected areas and rural areas related them. Of course, not every area can generate thriving rural tourism business, but only those areas where tourism resources can become tourist influence entrepreneurship and support local authorities. Protected areas have recognized their tourist potential. By this potential, the human community may or may not benefit, given the purpose for which it decided to manage it. Transforming potential of the resource potential that is capitalized depends to a greater or lesser capacity to absorb community resource for recovery. Therefore, the dynamicity of these resources, linked directly by the ability of communities to realize the value of existing potential and willingness to integrate this potential in the economic sense. Basically it's existence entrepreneurship. Hence the structure and function occur tourism resource to be included in a specific territorial linked to a sense of recovery, respectively, becoming the dominant tourist: rural, mountainous, white, cross, etc.. Even if the Romanian rural businesses do not have appropriate access to information, knowledge-based businesses and growing across the world, have a low environmental impact and are a major opportunity to create rural jobs. They include: financial services, tourism, manufacturing, construction, trade, transport and communications. The working hypothesis of the study is the idea - the research outlined earlier - that entrepreneurship, in whatever space can be changed by knowledge that constantly made and addressed by all actors responsible for local economic development, determines the occurrence of a leap mentality premises collective evolution toward a higher open performance and welfare.
