The Nexus between Dynamic Efficiency of Government Policy and Export Performance in Renewable Energy Technology Sector: A Dynamic Panel Approach

This paper tests the relationship between dynamic (innovative and green-innovative) efficiencyof government policy and export of renewable energy technologies using the dynamic panelapproach. Panel data for 20 Organization for Economic Cooperation and Development (OECD)countries for the period covering 1994-2012 were used. Taking into account the results ofpanel framework analyses, the panel vector autoregression (VAR) model in the first differencewas used to test the relationship among the variables in question. Panel generalized method ofmoments (GMM) estimation was conducted, then on the basis of the difference in GMMestimation results, causality was determined by running Walt tests on the coefficients ofvariables. The results from the study show that there is no long-run linear causal relationshipbetween dynamic innovative or green-innovative efficiency of policy and export. Moreover,there is a short-run linear causal relationship running from dynamic innovative efficiency ofpolicy to export, and between dynamic green-innovative efficiency of policy and export
