Abstract
"One of the most challenging issues in the recent literature on technological development has been related to the ""geography of innovation"" or ""spatial clustering of innovations"". The relationship between innovation and geography is a topic of growing interest in both economics and regional science. The main questions are the extent to which knowledge spillovers (knowledge externalities) are geographically localized and their impact on the innovative performance of regions. The main hypothesis is that knowledge spillovers are space dependent because spatial proximity is important in the transmission of knowledge and ideas. Our approach examines the issue of knowledge spillovers from an explicit spatial econometric perspective, yielding more precise insights into the range of spatial correlation between patents, R&D expenditure, and employment, across different geographical areas. The proposed study represents the first attempt in the literature to provide a systematic analysis of the relationship between knowledge spillovers and elasticity of labor in the European Union (EU-14 countries) at the lowest possible level of spatial aggregation. We do so by analyzing R&D expenditures made by firms and universities, number of patents, and employment in 14 countries (EU-2002) at NUTS 2 (Nomenclature Units Territory Statistics) level."
