The literature has always shown that there are two important factors in the improvement of a country's research output: Gross Domestic Product (GDP) and R&D Expenditures. Taking the discussion a step further, and in an effort to provide policy recommendations on what is needed to boost research capacity, this paper aims at decomposing the change in energy research papers of five countries (Australia, Canada, Germany, UK and US) into four factors: GDP, R&D intensity (ratio of total R&D to GDP), energy R&D rate of return or productivity (number of energy-related papers per unit of energy R&D expenditure), and energy R&D priority (share of energy R&D to total R&D expenditure).
