INDUSTRY STRUCTURE FOR INDUSTRIAL ROBOTS
At present about 130-140 firms in Japan are manufacturing robots of whom 37 are members of the JIRA. Most large manufacturers, actual or potential, are JIRA members but some important exceptions should be noted--Matsushita Electric Industries, Osaka Transformer Corporation, Seiko, and the pen manufacturers.
The existing robot makers are widely distributed over the whole
range of business scales.
In size of
capitalization, robot makers are to giant corporations. In examining
the table below, the capitalization (equal
companies with less than Y $ 500, 000) represents 41.
100 million 4% of the enterprises;
the medium firms with (Y 100- 300 million) represent 23. 3%, while the firms
with over Y 3 billion capitalization (equal to about $ 15,000, 000) represent
35. the 500
3% of the corporations.
The same trend is evident when we examine
robot makers by number of employees. The small firms with less employees represent 46. 6% of the total, the medium firms with 500
30. 1%, and
based on a
giant firms with survey in 1979,
over 5000 employees, 23. of 133 robot makers, is
3%. This shown below:
