Chapter 14 The Role of Cross-Country Knowledge Spillovers in Energy Innovation

Abstract

Purpose – This chapter aims at investigating the impact of cross-border knowledge spillovers on technological innovation in the renewable energy sector.

Methodology/approach – The analysis presented in the chapter assumes that technological knowledge exhibits several tacit elements and requires established connections to flow between countries. A new measure for knowledge spillovers is obtained by weighting international R&D stocks through bilateral trade flows. The country-level patenting activity is modelled through a knowledge production function. The sample includes 18 OECD countries over the 1990–2006 period. Estimates are obtained through panel data techniques.

Findings – Our econometric results show that international knowledge developed by other countries has positive effects on the focal country's innovation in renewable energy technologies. Cross-country linkages, rather than mere geographic proximity, are found to favour cross-country knowledge spillovers.

Impact – The research contributes to the design of energy innovation policies. Public R&D is confirmed to be a relevant input to energy innovation. Coordination between countries in energy R&D activities can be required, particularly when countries maintain mutual linkages.

Originality – This study adds empirical evidence on the effect of cross-country knowledge spillovers and on the channels through which technological knowledge diffuses globally. It contributes to the emerging empirical research on energy innovation.
