摘要：This paper analyzes research efficiency at the industry level in manufacturing
for 13 European member and four nonmember countries during 2000 and 2004. A
unique dataset was compiled that matches patent applications at the European
Patent Office (EPO) to industry-specific R&D inputs from EU KLEMS. We find
that Germany, the United States, and Denmark have the highest efficiency scores
on average in total manufacturing. The main industries that are at the
technology frontier are those involved in electrical and optical equipment and
machinery. Separate frontier estimations for these industries, conducted without
the constraint of a constant technology frontier, provide additional support for
our results.
