# 17.07 The spatial evolution of the Italian motorcycle industry (1893-1993): Klepper’s heritage theory revisited

Andrea Morrison, Ron Boschma


This paper investigates the spatial evolution of the Italian motor cycle industry during the period 1893-1993. We find support for both the heritage theory of Klepper and the agglomeration thesis of Marshall. Indeed, being a spinoff company or an experienced firm enhanced the survival rates, but we also found a positive effect of being located in the Motor Valley cluster in Emilia Romagna. Interestingly, this beneficial effect of a cluster could not be found outside the Emilia Romagna region. This might indicate the importance of a favourable local institutional environment, as propagated by the Emilian district literature.

# 14.18 Do spinoff dynamics or agglomeration externalities drive industry clustering? A reappraisal of Steven Klepper’s work

Ron Boschma


Klepper’s theory of industry clustering based on organizational reproduction and inheritance through spinoffs challenged the Marshallian view on industry clustering. The paper provides an assessment of Klepper’s theoretical and empirical work on industry clustering. We explore how ‘new’ his spinoff theory on industry clustering was, and we investigate the impact of Klepper’s theory on the economic geography community. Klepper’s work has inspired especially very recent literature on regional branching that argues that new industries grow out of and recombine capabilities from local related industries. Finally, the paper discusses what questions on industry location are still left open or in need of more evidence in the context of Klepper’s theory.
