Large firms, entrepreneurship and regional development policy: 'Growth poles' in the Mezzogiorno over forty years

Large firms are often perceived by economists and policy-makers as ‘growth poles’ to promote development in backward regions. The idea behind the ‘growth poles’ is that large firms may have a leverage effect on the birth and growth of small and medium sized firms. Regional policy in Italy, particularly in the Mezzogiorno, has subsidized large external plants since the 1950s. A new wave of planning agreements in the 1990s is going to redesign and to strengthen this policy orientation. This paper offers empirical data on plant location and growth at provincial level over 40 years. There is no evidence of overall long term growth impact of large acternal plants in the Mezzogiorno, while there are interesting variations by sectors. A theoretical interpretation of the impact of large firms on local entrepreneurial resources is offered, pointing to the negative effects of large firms on the supply of local entrepreneurship. Policy implications are discussed.
