This article theoretically and empirically studies the association between research and development investments in renewable energy (RE) and oil prices at the country level. We find a positive and robust association between patent counts for RE and price of crude oil using a panel of 46 countries for 1991–2013 in a fixed‐effects hurdle Negative Binomial control function framework. Results suggest that net conventional energy importing countries are more likely to invest in RE when oil prices increase. Countries with more electricity production, less emissions, and greater energy utilization generate more RE patents per year.

常规能源定价会引发可再生能源创新吗？非线性方法的新证据

本文从理论和经验上研究了国家层面对可再生能源（RE）的研发投资与石油价格之间的关联。在固定效果障碍负二项式控制功能框架中，我们由46个国家组成的小组在1991-2013年间发现可再生能源专利数量与原油价格之间存在正相关关系。结果表明，常规石油净进口国在油价上涨时更有可能投资可再生能源。拥有更多电力，更少排放和更多能源利用的国家，每年会产生更多的可再生能源专利。
