摘要

This study empirically investigates the causal relationship between research and development (R&D) expenditure and innovation in Greece, during the period 1981-2009. It uses time series analysis, the theoretical background of the endogenous knowledge-based growth theories and the annual number of patent applications to the European Patent Organization as proxy of innovation activity. The Johansen method is applied to examine the possibility of co-integration. The results confirm the presence of a long-run relationship between R&D expenditure and innovation. The total and private R&D expenditure appear to have a positive effect on total and business innovation. In addition, the public R&D expenditure has a positive influence on business and total innovation, which indicates the existence of significant externalities of public sector research. The long-run elasticity of innovation with respect to R&D expenditure is estimated to be, on average, 1.9. Implications for public policies and related practices are formulated.
