Morfometría y composición química de una laguna de gravera

Abstract

Knowledge spillovers have been used to explain the increased rate of innovation that is found in R&D clusters. We estimate a knowledge production function for industrial R&D Activities using China's Provincial data. Controlling for R&D expenditures, R&D personnel and R&D expenditure by colleges, We investigate the link at a regional level between localization of knowledge spillovers and R&D activities clustering. The results indicate that R&D spillovers are localized and it has an obvious spatial attenuation effect. © 2008 IEEE.
