Pulished in 2000, a selection of contributions presented in 1998 at the conference of Udine entitled, "The Development of Industrial Districts in Italy". The theoretical aim of the book is to explain the dynamic mechanism of the growth of Italian "industrial districts" shifting attention from "Marshallian industrial districts", where focus is not just on the decentralization of production among small-batch firms. Determinant factors explaining growth seem related to the ways in which firms explore the markets, learn tacit knowledge, network with subcontractors and make incremental innovations. In substance, the work offers a cognitive approach to the issue of industrial districts.

Fiorenza Belussi, Giorgio Gottardi, and Enzo Rullani This volume collects some papers presented at the Vicenza conference "The Future of Districts", held in June 1999, organised by the Department of Technology and Management of Industrial Systems of the Faculty of Engineering of Padua University, with the collaboration of several engineers, industrial economists, and experts in the issue of technology management. This was the starting point of a long-lasting and painful colIective discussion, the results of which are documented here, during many meetings of this "itinerant" group, including the workshop in Padua, organised by Professor Luciano Pilotti and held in May 2001, "Systems, governance & knowledge within firm networks" at the Department of Economics of the University of Padua, and the recent international research seminar, held in May 2002, in Rome at the Tagliacarne Institute, within the EU sponsored project "Industrial districts' re location processes: identifying policies of EU enlargement West-East ID". The reason we decided to organise this book was not only to underline the importance of the industrial district (ID) model as a tool of propulsive local growth in a country like Italy. On the contrary, the idea that moved us was the theoretical dissatisfaction with the way in which the phenomenon of local development and industrial clustering of specific industries was treated in the international approach of the various disciplines.

The Technological Evolution of Industrial Districts collects a wide array of theoretical and empirical contributions on the issue of industrial districts and gives insights into the complexity of industrial clustering, which has received growing international attention in the last decade. The industrial district model has been acknowledged as a tool of local growth. Using this background, the contributors deal with the dynamics of economic and social processes that generate the various possible patterns of evolution at a local level. The authors analyze districts not just as spatial concentrations of specific industries but also as organizational forms that are created throughout an historical process rooted in the economic and social dimension of a specific place. This is the basis, they argue, on which activities, skills, knowledge, innovation, and institutions are settled, and continuously changed, in reaction to endogenous drifts and exogenous shocks. IDs are viewed here as densely populated industry-specific organizations composed of complementary enterprises, territorial identity, embedded institutions, trust, and social capital. In other words, the ID "formula" goes back to the idea of an existing "dominant" industry (or product) specialization in the territory and a close "community" of people and firms co-located in a small area that is typically smaller than a province. Starting from the Marshallian concept of clustering, the book incorporates the more recent literature on clusters, proposing a distinction among these terms often used as synonymous.

The book is divided into three parts. Part I provides a background discussion of the theory of industrial districts, bringing into the traditional Italian approach the Nordic studies based on the theory of knowledge-based organizations and the institutional perspective of the French regulation school. Part II, the book's core, develops a cognitive approach to the theory of industrial districts. Part III presents some empirical evidence on the new evolutionary design of traditional and high-tech industrial districts localized in Italy and in France.

This volume will be particularly useful as a reference work for policy makers and as a supplemental text for courses in applied economics and business, industrial organization, industrial districts/clusters management, and network economics.
