Purpose-Countries that can adapt to the pace of technological developments, follow and use this speed have a stronger economy and obtain a significant competitive advantage in the global arena. Therefore, the countries make various regulations to increase the technological achievements, access to the global technologies, adapt to the rapid technological transformation and organize their substructures according to these technologies. Technology Achievement Index (TAI), which is one of the studies to evaluate the technological performance of countries, classifies countries according to their technological achievements. Conclusion-According to TAI-16 classification, the countries were identified as follows; 40 countries as Leaders, 38 countries as Potential Leaders, 17 countries as Dynamic Adopters, and 10 countries as Marginalized. Furthermore, TAI ranking of the 105 countries was created. In this classification, while Switzerland had the highest with 0.813 TAI value, Ethiopia had the lowest value with 0,028 TAI value.

Purpose-Information and communication technologies have a strong influence on sustainable economic growth and global competition. The countries that adapt to the speed of these technologies and have skills, infrastructure and accessibility to use these technologies will benefit from the strong influence of ICT. Various analyses, measurements, and comparisons are made to measure this effect. Methodology-Information and Communication Technologies (ICT) Development Index prepared annually by the International Telecommunication Union (ITU) is a composite index calculated from eleven indicators to monitor developments in the field of ICT and make the comparison between countries. Findings-In this study, the efficiency of the indicators in the ICT Development Index (IDI) in OECD countries was examined by data envelopment analysis. Conclusion-By evaluating the relative effectiveness of the countries, the efficiency scores and reference values were determined for 2015.

Purpose -In this study, the ICT development level of Turkey is aimed to evaluate. To this end, ICT development Index (ICTDEV-I) calculated for Turkey-wide and 12 regions from the years of 2013 to 2017 separately for each year. Then, comparative analysis and recent situation analysis are performed. Methodology -Following the methodology used by the International Telecommunication Union (ITU), Factor Analysis is used and the Principal Component Analysis method is chosen to calculate the ICTDEV-I and to determine the weight of each indicator. Findings-The regions are ranked according to the calculated index values. ICTDEV-I values of 12 regions are increased within five years. Conclusion-Within five years, there has not a considerable change in the index ranking of the regions, and many regions have kept their place in the index. Considering the ICTDEV-I values of the regions, while Istanbul has the highest value, the Southeast Anatolia Region has the lowest value.

Purpose -The aim of this study is determining the development level of 80 countries in the ICT, measuring the performance of countries over time and revealing the digital divisions among the countries. Methodology -Following the methodology used by the International Telecommunication Union, ICT Development Index (ICTDEV-I) of 80 countries are calculated separately for each year from 2010 to 2016. To calculate the index and determine the weight of each indicator, the Factor analysis is used and the Principal Component Analysis is chosen. The countries are grouped according to their ICT levels to reveal and compare digital divisions among them. Findings-The countries are ranked according to the index values and comparative analysis are presented. The size of the digital divide and whether shrink of this division among the countries is analyzed. Conclusion-There is an increase in the index values of all countries included in the ICTDEV-I. Digital divisions are increased between developing and less developed countries.
