885,643....!

First, let me review how I got there, and then we can examine some of
the sources and details in a bit more depth.
From the source I cited earlier:
http://www.computerworld.com/managementtopics/management/story/0,10801,89722,00.html
we have a figure for the number of technology companies in the United
States: 285,000
The GDP for the US in 2002 was $10,207 billion.
The GDP for the world as a whole was $31,720 billion.
So, the US accounts for about a third of the overall global economy,
or more precisely:
10,207 / 31,720 = 0.321784363 = approximately 32.18%
Dividing the two figures:
285,000 / .3218 = 885,643
gives us a result -- 885,643 -- as a reasonable approximation for the
number of technology companies in the world.

The GDP numbers for the US and the world as a whole come from the
World Bank, and can found on the web at:

I also tried to pin down the source of the figure of 285,000 hi tech
companies in the US. In the process, I came across some data that may
be useful, and which I suspect was the source of the 285,000 figure,
though I have not been able to confirm this.
The US Census Bureau conducted an extensive census of the economy for
2002, and data from this effort is just now beginning to trickly out.
The Bureua has released its preliminary 2002 overview survey data:
http://www.census.gov/econ/census02/advance/TABLE2.HTM
Table 2. Advance Comparative Statistics for the United States
The table (which also includes 1997 data for comparison), reports on
the number of businesses in the US in a great many different
categories. It's pretty much a judgement call which categories you
would consider to be "technology companies", but just as a
for-instance:
Computer and electronic product manufacturing 2002 ................ 15,698
Electrical equipment, appliance, and component manufacturing.........6,420
Electronics and appliance stores 2002 ............................. 46,724
Publishing industries 2002 ........................................ 32,239
Motion picture and sound recording industries 2002 ................ 22,831
Broadcasting and telecommunications 2002 .......................... 57,277
Information services and data processing services 2002 ............ 24,929
=====
As you can see, it doesn't take that many categories to begin
approaching the 285,000 figure. When the data is made publicly
available in a finer level of detail, it will be much easier to sort
the sub-categories into "high tech" operations (e.g. "software
publishers"), and make a more definitive count of businesses (at least
in the US).
Well...I hope this provides you the information you were after
(without going overboard!).
Paul...If there's anything else you need -- or if anything here is not
clear -- just let me know by posting a Request for Clarification, and
I'll be happy to assist you further.
