On the Roman origins of entrepreneurship and innovation in Germany
研究德国地区创业与创新差异是否可追溯至两千年前的罗马统治，发现罗马统治对创业与创新的水平和质量有持久的正面影响，可能源于区域间社会与经济交流的印记。
We investigate whether the development of regional disparities in entrepreneurship and innovation in Germany can be traced back to Roman rule 2000 years ago. We find a lasting positive Roman effect on the level and quality of entrepreneurship and innovation. This effect might be due to the imprint of local hard factors, such as interregional social and economic exchange, particularly emerging from the integration into the Roman Empire. This effect remains robust when a number of other significant historical developments are taken into account. We hope that these results stimulate a scholarly debate on the probably underestimated importance of ancient roots of economic development.
