摘要：This paper describes the approach applied and the results of an evaluation of the effects of the
Swiss government programme to promote the diffusion of Advanced Manufacturing
Technologies (AMT) from 1990 to 1996. The method used is based on specifying and
econometrically estimating with firm data simultaneously an adoption equation which,
besides the main explanatory variables as proposed by the theory of technology diffusion,
includes a policy variable, and a policy equation with a set of firm characteristics and an
adoption variable as regressors. The results are consistent with a positive impact of promotion
on adoption of AMT, particularly a more intensive adoption of AMT for firms which did not
use AMT when the programme started
