Two traditional models of global expansion were evaluated in an explor
atory effort to explain the globalization patterns of emerging high-te
chnology companies. In-depth field interviews were conducted with 19 M
assachusetts-based companies that supply software or peripheral produc
ts for desktop computing to explore: their timing and aggressiveness i
n entering markets outside of North America; their structures and patt
erns for expansion; and their success. Sampled companies report nondom
estic revenues ranging from 6% to 58% of their totals. Statistical ana
lyses of ''globalization success,'' defined here as how quickly a comp
any achieves substantial percentage of revenues from nondomestic marke
ts, support an integrated model of globalization that combines a clust
er of other influences with elements of Vernon's specific product cycl
e model and aspects of the more generic internationalization process m
odels. In accordance with Vernon, high-tech products are developed pri
marily for the home market but are soon transferred overseas, more slo
wly to ''lagging markets.'' In contrast with Vernon, many different se
lling arrangements are employed and overseas production does not follo
w for most high-tech firms. In accordance with the general internation
alization theory, when high-tech companies perceive foreign markets as
risky they proceed cautiously, often using outside specialists to fac
ilitate marker entry and increase their involvement over time as their
familiarity increases. But in contrast with this, many high-tech firm
s, especially the most successful, do not even perceive such riskiness
and do not exhibit such caution. Unrelated to either of those two mod
els, and building upon the work of Rugman et al. [1], globalization su
ccess is most strongly linked to how aggressively senior management al
locates internal resources to developing an overseas business model th
at approximates the company's U.S. model of selling/distributing. Exte
rnal environmental forces, too, such as the varied adoption rates of t
he underlying desktop computing platforms themselves as well as regula
tory factors, also affect globalization of high-tech products and comp
anies. (C) Elsevier Science Inc., 1996
