Strengthening Institutions for a Green and Digital Future: Regional Evidence from Europe's Twin Transition
研究了制度质量如何促进欧洲区域的绿色与数字双重转型，通过构建面板数据并使用Tobit模型，发现更高的制度质量显著提升双重转型专利的数量和强度。
ABSTRACT This paper explores the role of institutional quality in fostering the twin transition across European regions. We construct a novel panel dataset at the NUTS2 level (2006–2020), combining patent data from the OECD REGPAT with the European Quality of Government Index. Twin transition innovation is measured through the fractional count of patents in technologies simultaneously addressing environmental sustainability and digital transformation. Institutional quality is captured both through EQI and its key dimensions. Using a Tobit regression model with panel data, we find that higher institutional quality significantly increases the likelihood and intensity of twin transition patenting
