EXAMINATION OF THE USE OF INFORMATION TECHNOLOGIES IN TURKEY BY MCDM METHODS: 2014-2021 PERIOD

Electronics and communication sector investments, which have increased with the decreasing infrastructure costs in recent years in Turkey, Information Communication Technologies (ICT) is becoming widespread. According to the data of the Turkish Statistical Institute (TUIK) for 2021, the number of households with internet access has increased to 92%. The development of information and communication technologies provides social transformation by affecting the development speed of countries. Despite the regional differences in Turkey, the development of the informatics infrastructure has shown great improvement. In this study, with Multi-Criteria Decision Making Methods, a model that can measure the development performance of the regions in Turkey towards the use of information technologies at the statistical region level has been examined. In the model created, PSI (Preference Selection Index) was used to weight the criteria, and WEDBA (Weighted Euclidean Distance Based Approach) methods were used to evaluate the ICT usage level of the regions. The data in the study was taken from the TUIK database and is based on the Household Information Technologies (IT) Usage Survey of 2021 carried out by the institution. The criteria for the use of information and communication technologies consist of internet access, broadband, fixed broadband, mobile broadband, regular internet usage and internet usage. According to the findings of the study, it can be said that while the most important criterion was internet access in 2014, it was mobile bandwidth in 2021. Within the scope of the study, Istanbul and East Marmara regions showed the best performance. In addition, it was concluded that the Southeastern Anatolia region, which showed the most development, was followed by the Western Anatolia, Mediterranean, Central and Middle East Anatolia regions, and the development in other regions was less than the aforementioned regions.
