For the measuring of digital divide in the e‐Government field, the following indicators were chosen, taking into account their meaning and the actual data availability( Figure 5):
• enterprise use e‐Government for obtaining information from site of public institution,
• enterprise use e‐Government for downloading forms from the site of public institution,
• enterprise use e‐Government for sending the completed forms to public institution.
The suggested model, implemented with this set of indicators, could be classified to the group of measurement tools which investigate the intensity of use of e‐Government services. Different choice of benchmarking indicators could align it into different type of measurement tools.
Figure 5: Choice of indicators in sub‐indices
In this particular case, there are two sub‐indices in the model, one for each type of digital divide. Each of these two sub‐indices is expressed through three selected indicators. The formula for EGPI calculation is then as follows:
EGPI =,( 3) where the sub‐indices EGPIi are calculated according to the formula
where
EGPIi =, i = 1,2( 4)
Xjmax – maximum measured value of indicator Xj Xjmin – minimum measured value of indicator Xj.
7. Research methodology and results
The raw data used as the basis for calculation of EGPI in the field of economy originate from the survey on the usage of ICT in Serbia, carried by the Statistical Office of the Republic of Serbia for years 2009 ‐ 2012( Vukmirović, Pavlović and Šutić, 2009, 2010, 2011, 2012). In this survey the methodology of Eurostat was applied on enterprises( Eurostat, 2007). It was carried out by phone, on the territory of the Republic of Serbia( without Kosovo and Metohia), on the stratified sample, allocated on the following regions: central Serbia( without Belgrade), Vojvodina and Belgrade. The reference period was within three months before telephone interviews. The scope of the representative sample was 1200 enterprises.
The input data for calculation of sub‐indices and the total e‐Government polarization index EGPI are expressed in percentages. The examples of input data are shown in Figures 6, 7, and 8. These are the values of indicators I1, I2 and I3 for years 2009 – 2012, used for calculation of EGPI1( e‐Government polarization index caused by different size of enterprises).
