摘要：German chemical manufacturing industry is marked by two major structural changes
during 1992-2004. Firstly, number of firms was ranging extensively: from 676 to
901, while only 96 firms represented balanced panel. Secondly, size of the firm
dropped considerably-by 88%. This paper is intended to shed light on both
phenomena. Based on reliable census data analysis suggests the former evidence
be explained (i) by persistent poor performance of firms and (ii) by so called
"general purpose technology" argument. The latter phenomenon was found to be a
rational behaviour because numerous firms continually operated under decreasing
returns to scale.
