This study analyzes the causality relationship between economic growth and energy production (Electricity and Thermal Energy) and technological investments in Kazakhstan between 1993 and 2020 using Cointegration and Vector Error Correction Models (VECM), and also performs impact analysis. Cointegration analysis was used to determine whether there is a long-term relationship between the variables that became stationary after the first difference. Energy production proved to be an important contributor to the economic growth of Kazakhstan. Compared to energy production, technology investments have a more decisive effect on economic growth. Therefore, the importance of technology investments for countries has been emphasized once again.

The economic globalization in the century of competition increase assumes some new economic relations. In our opinion, one of the key points for state’s competitive recovery is the domestic tourism development which, in turn, requires some changes in the skilled personnel training. The research objectives are in conduct and analysis of the results of sociological survey among travel companies’ representatives working directly with graduates in the city of Almaty. In the course of the sociological research, we have applied the methods of generalizations, analyses, statistical distributions, expert judgments and comparisons. The conducted analytical research has allowed for studying the opinions of those specialists practicing in the tourist business and, thereupon, for making some conclusions and providing certain recommendations on the education quality improvement in training personnel for the tourist industry.

The economic, social, and ecological wellbeing of a society are all negatively impacted by the traffic congestion issue. Intelligent Transportation Systems (ITS) have been used to better sustainable transportation systems across the globe, helping to lessen the unsustainable effects of the clogged highway issue. The goal may be reached by examining the positive effects ITS deployments have had on urban areas in the United States. In addition to the statewide findings, we also do in-depth research on the economies of seven major Florida communities. A fuzzy-data envelopment analysis (DEA) technique is used instead of the conventional DEA approach for sustainability performance analysis in order to take into account the uncertainty in benefit and cost evaluations. While all of the ITS investments are very successful when looking at the cost-benefit ratio, the findings from the fuzzy-DEA method show that some of them are less efficient than others. This research's TBL findings give a fuller picture of the societal and economic benefits of ITS-related congestion reduction, including its drawbacks, indirect indicators, and environmental advantages. In addition, decision makers had positive findings from TBL analysis of ITS investments and comparisons of sustainability performance of ITS initiatives.
