A meta-analysis towards the effectiveness of startup accelerators
通过整合21项研究的68个效应量，发现参与加速器对新创企业绩效有显著正向影响，并识别出项目时长、队列规模等调节因素。
Abstract Accelerators have become crucial facilitators of entrepreneurial growth, yet empirical research on their effectiveness remains fragmented and inconclusive. To this extent, this paper conducts a comprehensive meta-analysis to synthesize quantitative findings and assess the impact of accelerator participation on new venture performance. By analyzing 21 primary studies and 68 effect sizes, the results reveal a statistically significant positive effect of accelerator participation. The study identifies key moderating factors, such as program duration, cohort size, sponsorship type, and regional context, which significantly influence venture outcomes. Additionally, the analysis highlights the presence selection biases within accelerator programs. This paper contributes to the theoretical understanding of accelerators by offering insights into their role in enhancing financial and operational dimensions of new venture performance. The findings provide valuable implications for both scholars and practitioners, laying the groundwork for future research on accelerator design and effectiveness.
