Abstract: The integration of digital technology and green technology can drive enterprises to optimize resource allocation and play an important role in achieving high-quality development. This research uses invention patent information to measure the digital and green technology integration behavior of enterprises, and takes A-share listed companies in emerging industries as samples to study the impact of digital and green technology integration on the high-quality development of enterprises and its mechanism. The study finds that the width and depth of the digital and green technology integration of enterprises have a positive impact and a positive U-shaped impact on the high-quality development of enterprises respectively, and the above conclusions are still valid after the robustness test. The mechanism analysis shows that the width and depth of digital and green technology integration can promote the high-quality development of enterprises by improving the mismatch of asset structure. Knowledge combination ability only positively moderates the relationship between the breadth of integration and the high-quality development of enterprises. The heterogeneity analysis shows that the significance of the impact of the width of digital and green technology integration on the high-quality development of enterprises shows a heterogeneity pattern of “eastern region>central region>western region,” and shows a more significant positive impact in the samples of non-state-owned enterprises, while the depth of digital and green technology integration only shows a significant U-shaped impact in the samples of eastern enterprises and non-state-owned enterprises. The research conclusions of this paper can enrich and expand the relevant theories of digital and green technology convergence, and provide practical support and policy enlightenment for China’s enterprises to promote the convergence of digital and green technology and promote the high-quality development of enterprises.

Key words: digital and green technology convergence, asset structure mismatch, high-quality development, knowledge combination ability
