基于资源依赖理论与动态能力理论，选取2012～2022年创业板企业数据样本，揭示数字技术应用对创业板企业成长性的影响机理。研究发现，创业板企业应用数字技术对其成长性有显著的正向影响，且该影响在民营企业、大型企业、东部地区和数字经济发展水平较高省份企业中表现更显著。进一步研究发现，创业板企业应用数字技术对成长性的正向影响受到动态能力的门槛调节，在跨越该门槛后影响显著为正。

Based on the resource dependence theory and dynamic capability theory, this study collects data samples of ChiNext companies from 2012 to 2022 to reveal the impact mechanism of digital technology applications on the growth of ChiNext companies. Research has found that the application of digital technology by ChiNext companies has a significant positive impact on their growth, and this impact is more pronounced in private enterprises, large enterprises, enterprises in the eastern region, and enterprises in provinces with higher levels of digital economy development. Further research has found that the positive impact of the application of digital technology on the growth of ChiNext companies is moderated by the threshold of dynamic capabilities, and the impact becomes significantly positive after crossing this threshold.
