Abstract
Today, tourism and the hospitality industry are playing an increasingly important role in the economy of Kazakhstan, creating multiplier effects and contributing to the development of related industries. The aim of the study is to quantify the impact of final demand for the hotel and restaurant sectors on the economy based on the intersectoral balance model. Annual statistical reports from the Bureau of National Statistics of Kazakhstan were used as initial data, aggregated into 15 broad industries. Methods were used to calculate coefficients of direct and total costs, output multipliers, income multipliers and value-added, as well as indices of direct and inverse intersectoral relations based on the Leontief model. Results showed that the hotel-restaurant sector had the greatest multiplier effect, with a multiplier of 2.929 for output and 0.691 for income. The value added multiplier was 1.686. The values obtained reflect a high degree of interconnection between the sector and other industries, and its ability to produce a significant cumulative economic impact with increased final demand. The findings of the study highlight the importance of the hotel and restaurant sector as one of the key drivers of economic growth, especially in terms of creating added value and stimulating employment. Practical significance lies in strengthening internal cooperation, which can further enhance the effect of increasing final demand for hospitality services. Future research could include the development of dynamic and hybrid approaches to account for changes in structure, price effects, and technology in supply chains.
