Highly productive firms use their capital, labor and material resource
s more effectively to create product values than do less productive fi
rms. A measure of this effectiveness is ''total factor productivity''
(TFP). studies have shown that gains in the TFP of individual firms ar
e directly related to the intensity of their investment in R&D, primar
ily to investments for product and process development. R&D expenditur
es for basic research also contribute to productivity growth, but thei
r contribution is indirect, enhancing the gains realized through produ
ct and process development. On the other hand a firm's R&D expenditure
s for technical service may have a negative impact on its productivity
growth. other factors such as the complexity of the R&D organization,
and technology planning practices also appear to influence the produc
tivity growth of firms.
