Introduction
Information and communication technology (ICT) has been recognized as a key factor in the economic development and growth of countries, especially in the last decades [3], [16], [19], [30].Development of ICT contributes to higher productivity, efficiency, gross domestic product, and a higher level of innovation activity [17], [20], [29].According to the European Commission, ICT drives 20% of productivity growth in the European Union countries [7].
The development of ICT impacts higher overall competitiveness in numerous ways.A positive impact of ICT usage can be found in many areas: the financial sector, health organizations, education and science, and public organizations [14].The usage of ICT increases development of e-skills and the quality of education systems, changes the structure of business processes, encourages employment and collaboration among individuals and facilitates everyday activities [2], [27].
Usage and application of the information and communication technology (ICT) differs in particular countries, which lead to the digital divide among countries [22], [29], which has a negative impact on the overall development of the information society [13], [15], [28].The digital divide does not present only the difference between using and not using ICT, but also the difference in the level of knowledge and skills which are necessary for using ICT [1].
According to numerous researches, digital divide is present in European countries.For example, Piatkowski [21] showed that ICT led to higher growth of productivity at macro and micro level in several post-transition countries which became EU members in 2004.He highlighted that the highest efforts were made by several countries such as: the Czech Republic, Poland, Hungary and Slovenia, followed by Romania.On the other hand, Slovakia and Bulgaria lag behind regarding economic development and ICT usage.This indicates that European leaders should invest more efforts in decreasing the digital divide [4], especially taking into account that EU countries are thriving to become the most dynamic and competitive knowledge-based economy and society [25].In order to maintain a competitive position on the market in the next several years, European countries should enhance development of ICT and e-skills, since educated employees with such skills are a crucial factor for competitiveness, growth and employment [5], [10].
In this paper, we investigate how ICT influences competitiveness of European countries through four areas (elearning, personal usage of the Internet, e-commerce, e-government).We attempt to determine if there are differences in the economic development of those countries and how ICT affects them.In order to attain this goal, we have conducted a two-stage analysis.In the first stage, the cluster analysis using K-means was used to organize European countries into sensible groupings for the year 2011, according to their usage of ICT.Defined clusters are compared using Anova analysis according to their competitiveness indices, using the Global Competitiveness Report.
The paper is organized as follows.The first section provides an introduction.In the second section data and the model specification are explained.Results of the cluster and the Anova analysis are described in the third section.At the end, a discussion and conclusion close the paper.

Methodology
In the following section, the methodological approach to the research will be presented: measuring ICT usage, measuring competitiveness, and statistical two-stage methodology.

Measuring ICT Usage
ICT usage was measured using four dimensions: e-learning, personal usage of the Internet, e-commerce, egovernment.

Measuring Competitiveness
The Global Competitiveness Report of the World Economic Forum (WEF) defines competitiveness as "the set of institutions, policies, and factors that determine the level of productivity of a country" [23].WEF measures the competitiveness with overall competitiveness index (Global Competitiveness index), three subindices, and 12 pillars.In its Global Competitiveness Report 2011 report the WEF measured competitiveness of 142 countries.In our work we used the data for the competitiveness of 32 countries (EU countries, Iceland, Norway, Macedonia and Turkey) in 2011.We used the data on the overall competitiveness index, three subindices, and 12 pillars, which comprises in total the data of 32 countries with 16 competitiveness indicators.Appendix contains the list of abbreviations used for the competitiveness indices in our paper.

Two-Stage Methodology
In this paper we have conducted a two-stage analysis with the goal to investigate how ICT influences the competitiveness of European countries.In the first stage we used cluster analysis in order to organize European countries into sensible groupings for the year 2011, regarding their usage of ICT.In the second stage we used the Anova analysis in order to compare defined clusters according to their competitiveness indices, using the Global Competitiveness Report.
The first stage: Cluster analysis.One of the best ways to understand a large amount of data is to organize them into logical groups.The cluster analysis presents a statistical method used for grouping objects based on their similar characteristics [12].Therefore, the main goal of the cluster analysis is to find structure in data and to group data into clusters based on their similarities.The three main purposes for using the cluster analysis are detecting: underlying structure, natural classification and compression [12].Scientific fields in which cluster analysis can be used are numerous, and its common applications include the following: image segmentation, documents generation, customer differentiation [24].There are several methods which can be used for defining the number of clusters, and one of the most popular is the K-means method [26].
In the first stage, data on the usage of ICT in 32 European countries were used for cluster determination.Using the non-hierarchical K-means cluster analysis, countries were grouped regarding indicators of development and usage of ICT: e-learning usage (individuals), Internet use (individuals), e-commerce (firms) and e-government usage (individuals).Using the K-means method, we chose to use four clusters as this is appropriate for our analysis according to the number of selected countries: The second stage: Anova analysis.The Anova analysis is often used in order to test differences among defined clusters [9], [11].In our paper, the analysis of variance was used in order to compare competitiveness of the countries of identified clusters.We compared countries in four clusters according to the average values of 16

Countries' Clusters
According to the K-means methodology conducted by means of indicators of ICT usage, 32 European countries are grouped into clusters.

Differences in Competitiveness among Clusters
In this section, results of the Anova analysis are presented.The analysis of variance is conducted in order to compare competitiveness of the countries of identified clusters (Tables 2-5).In order to estimate the relationship of e-learning usage and competitiveness of selected European countries in 2011, calculated average values of competitiveness indices of each cluster are presented in Table 2.In order to estimate the relationship of the Internet usage by individuals (e-banking and finding an employment) and competitiveness of selected European countries in 2011, calculated average values of competitiveness indices of each cluster are presented in Table 3.In order to estimate the relationship of e-commerce usage and competitiveness of selected European countries in 2011, calculated average values of competitiveness indices of each cluster are presented in Table 4.

Discussion
After the cluster analysis and the analysis of variance were conducted, the conclusions are drawn regarding the relation between ICT usage of countries and their level of competitiveness.
Table 6 summarizes the results of the analysis of variance for the year 2011.The statistical significance for the differences of calculated average index values of competitiveness for countries from identified clusters (using indicators of e-learning, the personal usage of the Internet, e-commerce and e-government) is shown.
The analysis showed that the calculated average index values of competitiveness for countries from identified clusters of e-learning, personal Internet usage, e-commerce an e-government usage indicators are statistically significant for all indices of competitiveness, mostly with the 1% probability.The exception is the Market size, which are not statistically significant different among none of countries' clusters, as well as the pillar of Macroeconomic environment that is not statistically significant different among e-learning clusters.
On the other hand, Cluster B has the highest level of the competitiveness according to e-commerce for most of the indices.This result could indicate that the countries that are most developed are still oriented towards their strong national markets and traditional marketing and sales channels.These are the countries in the e-commerce Cluster B: Austria, Finland, Luxembourg, the Netherlands, Germany, Sweden, and the United Kingdom.On the other hand, the countries those are more oriented towards the online marketing and sales channels are still lagging behind according to the competitiveness indices.These countries are in the e-commerce Cluster A: Belgium, Norway, the Czech Republic, Denmark, and Ireland.However, it can be concluded that the result indicate the existence of the positive relation between the level of ICT usage and country competitiveness.

Conclusion
Our research revealed that the aforementioned European countries, which are also the most competitive, lead in the usage and implementation of ICT when it comes to firms which invest significant funds in the development of ICT, as well as when it comes to residents who use ICT extensively.The research and the results confirmed that the impact of the use of ICT on the competitiveness of a country is different for particular groups of countries with regard to the level of economic and social progress.The research showed the existence of the digital divide among European countries.The most developed countries of Western, Northern and Central Europe are also among the most competitive countries in the world and they lead in investments and also in the development and the usage of ICT.
The contribution of this study is the identification of four clusters that could help less developed countries in achieving a higher level of ICT usage which will lead to their social and economic growth.The following countries stand out as the most developed with the highest level of ICT usage: Denmark, Finland, France, Iceland, Luxembourg, Norway, Sweden, the Netherlands, Belgium, Ireland and Austria, which are also classified in the first two clusters, Cluster A and Cluster B. Developing European countries whose residents and firms use ICT on a smaller scale in relation to the countries of the first two clusters (the Czech Republic, Lithuania, Hungary, Malta, Portugal, Slovakia, Slovenia, Spain, Bulgaria, Cyprus, Greece, Croatia, Italy, Macedonia, Poland, Romania and Turkey) form the Cluster C and Cluster D group.It is also important to point out that the Cluster D mainly contains countries that are among the last that entered the EU, as well as candidate EU countries.These countries economically and socially lag behind the developed European countries, taking into consideration the use of ICT, and the scale of the global competitiveness index on which they are ranked is much lower compared to the countries of the first two clusters.
We consider the findings of this paper a valuable indicator for those who are preparing European strategies for the next years.The results showed the existence of the digital divide, which means that new strategies and policies should be directed toward development and implementation of ICT in less developed countries.Although the number of users who use the Internet increases every year in the world, both in developed countries and developing countries, not everyone has the necessary knowledge, skills and abilities to use it in the right way to achieve the significant benefits from its usage.It is therefore important, in addition to the use of ICT, to also encourage young people to obtain education on the use and possibilities of ICT.In this way it is possible to encourage the development of the information society thus reducing the digital divide between countries.
Limitations of this research refer to data collection and the analysis, which is made for only one year, i.e. 2011, and only for European countries.Also, it could be possible to expand the number of indicators of ICT usage.Future research should therefore focus on the analysis of time series data and compare the results obtained for the several years in order to determine whether developing countries have made some progress over the past four years.Also, countries outside Europe should be included in the analysis, since these countries lag behind to the largest extent.
The overall competitiveness index (Global Competitiveness Index) is composed of three subindices (Basic requirements, Efficiency enhancers, and Innovation and sophistication factors) which are composed of pillars of competitiveness.The Basic requirements index is composed of four pillars of competitiveness: Institutions, Infrastructure, Macroeconomic environment and Health and primary education.The Efficiency enhancers subindex is composed of six pillars of competitiveness: Higher education and training, Goods market efficiency, Labour market efficiency, and Financial market development, Technological readiness and Market size.The Innovation and sophistication factors subindex is composed of two pillars of competitiveness: Business sophistication and Business innovation.

Table 1 :
Table 1 presents the clusters of the selected European countries grouped based on different dimensions of ICT usage in 2011, using K-means.The results revealed that 32 countries grouped into four clusters differ according to the employed dimension of ICT usage.Four clusters were detected using K-means and the data on four dimensions on ICT usage in 32 European countries in 2011.We named clusters as A, B, C and D. Countries in Cluster A have the highest average value of ICT usage in four dimensions: e-learning, personal usage of the Internet, e-commerce, e-government.On the other side, countries in Cluster D have the lowest average value of ICT usage.Average values of ICT usage indicators for different clusters are provided in Appendix A. Countries' clusters based on different dimensions of ICT usage, 2011Countries which lag behind developed countries regarding ICT usage are grouped into Cluster D (Bulgaria, Cyprus, the Czech Republic, Greece, Croatia, Romania, and Turkey).There is a lower rate of the ICT usage in the aforementioned countries for the purpose of e-learning, personal purposes, and e-government.E-commerce is developed the most in Poland, Macedonia, Bulgaria, Croatia and Greece in Cluster D. Therefore, countries in Cluster C are mainly situated in Southern Europe, with some Mediterranean countries.
Countries which are grouped into Cluster B for the purpose of e-learning, personal Internet usage, and e-government are: Estonia, Hungary, the Netherlands and the United Kingdom.E-commerce is popular in the following countries in Cluster B: Austria, Finland, Luxembourg and Sweden.Therefore, countries in Cluster B are situated mainly in Central Europe.

Table 2
reveals that average values of competitiveness indices indicators are the highest in Cluster A, in which countries whose citizens use e-learning the most can be found.The only exception is the average value of the competitiveness pillar Market size which has the lowest value compared to other values for countries from Cluster A. Countries which can be found in Cluster A are: Denmark, Finland, Iceland, Luxembourg and Norway (Table1).Average values of competitiveness indices from other clusters are related to e-learning usage.After Cluster A where countries with the highest average values are grouped, there are Cluster B, Cluster C and Cluster D where countries with the lower average values of competitiveness indices are, as well as the lower value of e-learning usage.Anova analysis revealed that calculated average values of competitiveness indices of the clusters for e-learning indicators are statistically significant for all competitiveness indices, except for the competitiveness pillars Macroeconomic environment and Market size.
