As the author could not find a reassuring mathematical and
statistical method in the literature for studying the effect of
information communication technology on enterprises, the author
suggested a new research and analysis method that he also used to study the Hungarian
economic sectors. The question of what
factors have an effect on their net income is vital for enterprises. At first, the
author studied some potential indicators related to economic sectors, then those indicators
were compared to the net income of the surveyed enterprises. The resulting data showed
that the growing penetration of electronic marketplaces contributed to the change
of the net income of enterprises to the greatest extent.
Furthermore, among all the potential indicators, it was the only indicator directly
influencing the net income of enterprises.
With the help of the compound indicator and the financial data
of the studied economic sectors, the author made an attempt to find a connection between
the development level of ICT and
profitability. Profitability and productivity are influenced by a lot of other factors
as well. As the effect of the other factors could not be measured, the results – shown
in a coordinate system - are not full but informative.
The highest increment of specific Gross Value Added was
produced by the fields of ‘Manufacturing’, ‘Electricity, gas and water supply’, ‘Transport,
storage and communication’ and
‘Financial intermediation’. With the exception of ‘Electricity, gas and water supply’,
the other economic sectors belong to the group of underdeveloped branches (below 50
On the other hand, ‘Construction’, ‘Health and social work’ and
‘Hotels and restaurants’ can be seen as laggards, so they got into the lower left
part of the coordinate system.
‘Agriculture, hunting and forestry’ can also be classified as a
laggard economic sector, but as the effect of the compound
indicator on the increment of Gross Value Added was less
significant, it can be found in the upper left part of the coordinate system. Drawing
a trend line on the points, it can be made clear that it shows a positive gradient,
that is, the higher the usage of ICT devices, the higher improvement can be detected
in the specific Gross Value Added.
