Historical roots of innovative entrepreneurial culture: the case of Italian regions
研究了1927-2017年意大利各省创业活动的持续性，发现高技术和低技术行业的持续驱动因素不同，前者依赖使用动力的企业家比例（特定角色模型效应），后者依赖工业企业家比例（一般角色模型效应）。
This paper investigates persistence in entrepreneurship across Italian provinces over the period 1927–2017. We distinguish between a ‘general’ dimension (sociopsychological) and a ‘specific’ dimension (learning) of the role model effect. Based on data obtained from a comprehensive survey conducted in 1927 by the Italian National Statistical Institute, we find different drivers of persistence across sectors: the only driver of persistence in high-technology sectors is the share of entrepreneurs using motive power (‘specific’ role model effect), while the share of industrial entrepreneurs (‘general’ role model effect) is an important driver of persistence in low-technology manufacturing and service sectors.
