The approach to estimation of the synergetic effect of the travel industry clustering in the region

The article deals with the approach to estimation of the synergetic effect arising in the regional economy as a result of the travel industry clustering. The approach is based on the determination of the group of indicators describing the synergetic effect in economic, environmental and social spheres of the region. The author has developed a scale based on the Sturgess-Lux function with the level of confidence probability of 0,95, which includes the threshold values of the interval and its identification.
