Regional knowledge spillovers: Fact or artifact?
Research Policy, 2008
The explanation of different levels of innovation and their spatial distribution represents the central focus of the analysis. The empirical literature documents the incidence of spatial autocorrelation in patenting activities and interprets them as evidence for knowledge spillovers. Alternatively, the authors propose the spatial pattern of input variables in innovation processes as driving forces of patenting autocorrelation. They analyze 51
Intra and inter: regional knowledge spillovers in European Union
Aim of this paper is to investigate the impact of intra-regional and interregional knowledge spillovers on regional new knowledge production. Knowledge diffusion in a region and between a pair of regions is definitely influenced by separate factors in a clear way. The most important thing, however, is to test the impact of these factors on knowledge spillovers when they operate, not separately but, simultaneously. We apply a knowledge production function to data for 210 European regions for a 12 years period (1995–2006). Our results indicate that the returns to scale with respect to the main inputs of the KPF, are increasing with the absence of spillovers and decreasing when knowledge spillovers exist. Technological diversity facilitates the creation of new ideas and knowledge. The cross regional technological proximity is positive and statistically significant. The spatial proximity is also positive and statistically significant. However, the simultaneous consideration of the spatial and technological proximity significantly influences the marginal effects of these independent variables on new knowledge creation. Thus, when a region is geographically contiguous to weak innovative systems then the knowledge spillovers are stronger between regions which innovate in similar technological fields. When a region is geographically contiguous to regions with high innovative activity the knowledge spillovers are stronger between regions which innovate in different technological fields. Finally, the location of a recipient region on the technological fields' trajectory influences the impact of the technological distance on knowledge transfer.

EnglishA Knowledge Production Function (KPF) analyzes if the national innovation systems (NIS) generate knowledge spillovers for their regions. Therefore, we include in the traditional KFP some variables that reflect the NIS of each region. In fact, we included 52 national and regional explanatory variables and applied a factorial analysis to reducing them to a few 'synthetic' ones. Our study offers some evidence on the existence of 'national' spillovers and they seems to be asymmetrical. Its intensity is lower in the technologically less developed regions than in those of intermediate technological development and scarcely exists in the case of the more developed or central regions.

Regional knowledge spillovers: a firm-based analysis of non-linear effects
Regional Studies
This article revisits the question of the role of knowledge externalities in firm productivity. It also addresses the overlooked issue of a plausible nonlinear effect and differences among industries. Using a panel of Portuguese manufacturing firms, it finds that regional knowledge spillovers differ substantially across industries and they are nonlinear, which is critical issue to promoting more assertive regional policies.
Innovation and geographical spillovers: new approaches and empirical evidence
Regional Studies
Innovation and geographical spillovers: new approaches and empirical evidence. Regional Studies. This special issue concerns the generation of knowledge and geographical spillovers, and it includes a selection of papers that cover existent research gaps with respect to the role of space in the promotion of knowledge spillovers and innovation. These papers analyse different typologies of innovation processes carried out in several geographical areas and highlight heterogeneities of these processes, after focusing on several determinants in innovation. Empirical results indicate the positive role of geographical spillovers and the importance of accurate matching among firms, in industry and with regard to regional characteristics, in order to ensure the generation of knowledge and innovation.
