As a typical representative of digital technology,industrial robots have become an important al-ternative to traditional labor,providing enterprises with an environment of"creative destruction".Whether they can improve the innovation ability of enterprises has attracted wide attention.Based on the micro-enter-prise data of China,this paper discusses the impact of industrial robot application on enterprise innovation a-bility and its mechanism.The findings indicate that the application of industrial robots can significantly im-prove the innovation ability,and effectively enhance the substantive innovation capabilities of enterprises.In addition,the mechanism test shows that the application of industrial robots can increase the demand for high-quality talents,improve the labor structure and enhance human capital,and then promote the innovation a-bility of enterprises,confirming the"talent gathering effect".At the same time,the upgrading of production technology brought about by the application of industrial robots will promote production efficiency,thereby improving the innovation ability,confirming the"productivity improvement effect".Further analysis shows that inlabor-intensive state-ownedenterprises with higher labor costs and higher financial risk,and those with higher external market competition,the application of industrial robots has a more significant role in promo-ting the innovation ability.This paper expands the researchof industrial robots andinnovation capabilities,and has certain reference significance for promoting the transformation of enterprise labor factors,improving the human capital structure,and assisting the intelligent transformation and upgrading of China's manufactur-ing industry.
