This paper analyses the policy implications of territorial competition
; that is the promotion of local economic development in competition w
ith other territories. It does so both in analytical and empirical ter
ms moving from a wider supranational and analytical standpoint to a mo
re practical and local one, The impact of territorial competition in w
elfare terms depends critically on the perspective adopted. Some polic
ies are pure waste even from the point of view of the initiating terri
tory. Other policies may have a positive impact in economic welfare te
rms, viewed from the perspective of the territory, but be zero sum fro
m a wider perspective. There may also be policies, however, which incr
ease economic welfare, both locally and from a wider perspective. This
suggests that there is a case for providing a supranational regulator
y framework. The empirical section first examines the evidence as to w
hether local policies for economic growth do, in fact, have any impact
. The paper concludes with an examination of the actual policies pursu
ed in a sample of European regions and draws out some conclusions for
local policy makers.
