60 It should be noted that the National Innovation Survey and the EU's "Third Joint Innovation Survey" differed in their methodologies in that the former performed sampling with replacement to the population represented by the number of companies, while the latter performed sampling with replacement to the population represented by the number of employees, and bias may have existed in the responding companies. Consequently, the proportion of companies in Japan that have achieved innovation may have been excessively small. The results of the "Third Joint Innovation Survey" were announced in "Innovation in Europe-Results for the EU, Iceland and Norway" from Eurostat.
