The entrepreneurial ecosystem clock keeps on ticking – A replication and extension of Coad and Srhoj (2023)
重复并扩展了Coad和Srhoj（2023）的研究，在荷兰发现生产性创业持续性的强证据，并进一步提出创业生态系统的质量和规模会影响这种持续性，为不同文献发现提供了调和。
A key hypothesis in the entrepreneurial ecosystem (EE) literature is that a positive relation exists between the quality of EEs and the prevalence of productive entrepreneurship. Recently, Coad and Srhoj (2023) argued that the quality of EEs should also be positively related to the persistence of productive entrepreneurship. However, using two different measures for high-growth firms in regions in Croatia and Slovenia, they found no consistent evidence for the persistence of productive entrepreneurship. This led them to conclude that the EE framework is not valuable for policymakers. We contend that their generalization is incorrect and that their findings are consistent with a further articulation of the EE approach. We build our argument in two empirical studies. In Study 1, we replicate the approach by Coad and Srhoj (2023) in the Netherlands, where we find strong evidence for the persistence of productive entrepreneurship. We argue that the differences found in the replication study can be explained by accounting for the quality and size of EEs. In Study 2, we follow up on this notion by formulating two new hypotheses about the effect of quality and size of EEs on the persistence of productive entrepreneurship but argue that this effect decreases in strength as the quality and size of entrepreneurial ecosystems increase. Our hypotheses are supported by data on EEs and innovative start-ups in Europe. Accordingly, our results reconcile the different findings in the literature regarding the persistence of productive entrepreneurship. Theoretically, our work provides a further articulation of the EE approach by explaining the persistence of productive entrepreneurship, in addition to the more commonly studied prevalence of productive entrepreneurship. We conclude with policy implications of our findings. • Persistence of productive entrepreneurship is a key output of entrepreneurial ecosystems. • Persistence of productive entrepreneurship is stronger in larger than in smaller regions. • Persistence of productive entrepreneurship is stronger in high-quality than in low-quality entrepreneurial ecosystems.
