A gravitációs modell és a gravitációs törvény összehasonlítása

The role of transport in European tourism flows

“…As concluded by Dusek (2003) in his work on the gravity model: »With the exponent increasing, the intensity of interregional connections becomes more distance sensible and collaterally the relevance of masses will gradually decline.« By applying the spatial interaction model (Table 1), data on the number of guests can be sufficiently estimated. Therefore there is a relatively close connection between the interaction ability of the starting area, the attraction of the destinations, and the turnover estimated on the basis of destination competition and the actual number of guest nights.…”

The Application of Gravity Model in the Investigation of Spatial Structure

“…As the exponent, c, increases and the intensity of inter-regional relations becomes more sensitive to distance, this significance of masses gradually decreases [5]. The minus sign express mathematically, that the masses attract each other (see Figure 1).…”

Investigation of spatial structure: modelling approach

“…As the exponent, c, increases and the intensity of inter-regional relations becomes more sensitive to distance, this significance of masses gradually decreases (Dusek 2003). The minus sign express mathematically, that the masses attract each other (see Figure 1).…”

“…The gravitational theory is a theory of contact, which examines the territorial interaction between two or more points in a similar way as correlations are analysed in the law of gravitation in physics. According to Dusek (2003), despite the analogy, there are significant differences between gravitational models used by social sciences and the law of gravitation used in physics. It is worth bearing in mind that "the gravitational model is not based on the gravitational law".…”
