The existing research on industrial districts is fragmented, and yields conflicting advice for managers about the benefits and costs of locating in an industrial district. We resolve much of this ambiguity by synthesizing and integrating the existing research, and developing a typology of districts based on the continuous dimensions of need for coordination and centralization of control. In so doing, we elucidate why different types of industrial districts have different structures, and different competitive implications. We introduce four archetypes of industrial districts (based on extreme values of our two dimensions), and for each we discuss the benefits and costs of locating in the district, the sources of competitive advantage for members of the district vis-a-vis non-members, and the sources of competitive advantage a district firm may gain over other members of the same district.

During the 1980s the Marshallian concept of industrial district (ID) became widely popular due to the resurgence of interest in the reasons that make the agglomeration of specialised industries a territorial phenomenon worth being analysed. The analysis of clusters and IDs has often been limited, considering only the local dimension of the created business networks. The external links of these systems have been systematically under-evaluated. This book offers a deep insight into the evolution of these systems and the internal-external mechanism of knowledge circulation and learning. This means that the access to external knowledge (information or R&D cooperative research) or to productive networks (global supply chains) is studied in order to describe how external knowledge is absorbed and how local clusters or districts become global systems. It provides a unified approach; showing that existing capabilities expand when locally embedded knowledge is combined with accessible external knowledge. In this view, external knowledge linkages reduce the danger of cognitive ‘lock-in’ and ‘over-embeddedness’, which may become important obstacles to local learning and innovation when technological trajectories and global economic conditions change.

Italian industrial districts (IDs) recently attracted international attention because their performance during the last few decades contradicted the alleged weakness of industrial structures based on SMEs in "traditional" sectors. The book analyses some developments taking place in Italian IDs and local systems of production that can represent a new stage of evolution for the backbone of the Italian economy. Based on the extensive use of original databases three main trajectories of change in IDs are presented. The first trajectory is the increasing role of "groups" of manufacturing SMEs arising from mergers and acquisitions as well as spin-off growth processes at the "family firms" level. The second one is the consolidation of innovation capabilities in IDs. And the third one is the internationalisation process of Italian IDs through both trade and foreign direct investment. The essays suggest that Italian IDs are again evolving by coherent adaptations which will have, however, uncertain outcomes.

'A Handbook of Industrial Districts is a very well-organized and structured collection of scientific works on the theory of industrial districts.' - Roberta Capello, Regional Studies In this comprehensive original reference work, the editors have brought together an unrivalled group of distinguished scholars and practitioners to comment on the historical and contemporary role 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.

This book outlines the historical framework and the main concepts of the literature on industrial districts. It illustrates a new approach to the study of industrial development, based on well-known industrial districts analysis. Academics, politicians and students interested in local development and also industrial development will find much to learn in Industrial Districts, as will industrial geographers and historians of industry and of economic thought.
