The effects resulting from the application of the concept of the sustainable development of rural tourism on Stara planina

The development of rural tourism on Stara planina (Old Mountain) has a positive impact on the economic development of the local communities in the area. However, if an adequate program of the sustainable development of tourism on Stara planina were made, that would also have positive effects as an accompanying factor contributing to the development of rural tourism. In particular, the results would show that there is a need for the preservation of the quality of the environment and the development of all resources, especially with respect to the realization of an economic profit. The aim of the paper is to detect the extent to which the effects arising from the development of rural tourism depend on the implementation of the program of the sustainable tourism development of the mountain. The method that makes the realization of a causal connection between these two phenomena possible is the linear regression analysis. The purpose of the regression analysis is to determine the shape of such a connection, i.e. the dependence between the observed phenomenon, by applying a mathematical formula and a range of corresponding assumptions. Therefore, it best describes the quantitative relationship between the variation in the observed phenomenon of reality, as well as the agent that serves to evaluate the predictive value and the dependent variable against the desired value of the explanatory variables or the effects resulting from the development of rural tourism on Stara planina
