In search of key performance indicators of regional competitiveness in the European Union
利用欧盟区域竞争力指数的40个指标，识别出知识工作者、就业率、劳动生产率、潜在市场规模和不在教育就业培训中这五个关键绩效指标，并发现劳动力市场效率支柱对区域竞争力分类至关重要。
Abstract This study investigates key performance indicators (KPIs) affecting regional competitiveness in the European Union (EU) and compares its performance across two groups of EU regions identified by their development phase based on the path dependence argument. Utilizing 40 indicators from the Regional Competitiveness Index (RCI) across 268 NUTS2 regions, it identifies five critical KPIs: Knowledge workers, Employment rate, Labor productivity, Potential market size, and not in education, employment, or training. The classification and regression tree decision tree reveals the labor market efficiency pillar as crucial for RCI classification. Offering unique insights into RCI indicators and their impact, this research provides a policy‐oriented perspective and suggests avenues for further comparative research.
