摘要

本文以 1976-2020 年间 81 个发达经济体和新兴市场经济体为样本，实证研究了经济和政策不确定性对绿色创新的影响。我们的研究结果表明，不确定性的增加会导致绿色创新（以新的绿色能源专利数量衡量）的长期减少。这种影响适用于多种技术，在经济衰退和金融压力较大的时期，以及在环保法规不那么严格的国家，这种影响更大。重要的是，不确定性对绿色专利的影响大于对非绿色专利的影响。结果对几种敏感性测试都是稳健的，包括工具变量方法和差分策略。

Uncertainty and innovation in renewable energy

This paper empirically investigates the impact of economic and policy uncertainty on green innovation for a sample of 81 advanced and emerging market economies during the period 1976–2020. Our results show that increases in uncertainty lead to a long-lasting decrease in green innovation, measured by the number of new green energy patents. This effect holds for a wide set of technologies, it is larger during recessions and periods of higher financial stress, and in countries with less stringent environment protection regulations. Importantly, the effect of uncertainty on green patents is larger than on non-green patents. Results are robust to several sensitivity tests, including an instrumental variable approach and a difference-in-differences strategy.

期刊介绍： Since its launch in 1982, Journal of International Money and Finance has built up a solid reputation as a high quality scholarly journal devoted to theoretical and empirical research in the fields of international monetary economics, international finance, and the rapidly developing overlap area between the two. Researchers in these areas, and financial market professionals too, pay attention to the articles that the journal publishes. Authors published in the journal are in the forefront of scholarly research on exchange rate behaviour, foreign exchange options, international capital markets, international monetary and fiscal policy, international transmission and related questions.
