学习与实践

基于数字化、智能化融合视角衡量数智化发展水平，并借助SBM-GML模型评估城市绿色全要素生产率，实证分析数智化推动城市绿色发展的影响效果和作用机制。研究发现，数智化显著正向驱动城市绿色全要素生产率增长，且通过一系列稳健性检验。机制分析表明，数智化通过推动产业升级、优化资源配置和激励绿色创新，有效提升绿色全要素生产率。异质性分析表明，数智化对大型城市、创新禀赋较高的城市以及环境保护重点城市的绿色全要素生产率提升效应更加明显。据此，应从强化数智“新基建”战略地位、纵深推进实数融合、加快培育创新体系三方面协同发力，为驱动高质量发展、实现经济效益与绿色效益的双重跃升提供有力支撑。

Based on the integrated perspective of digitalization and intellectualization,we measure the development level of digital and intelligent transformation,evaluate urban green total factor productivity by means of the SBM-GML model,and empirically analyze the impact effect and mechanism of digital and intelligent transformation on promoting urban green development. The study finds that digital and intelligent transformation significantly and positively drives the growth of urban green total factor productivity,and has passed a series of robustness tests. Mechanism analysis shows that digital and intelligent transformation effectively improves green total factor productivity by promoting industrial upgrading,optimizing resource allocation,and stimulating green innovation. Heterogeneity analysis shows that the enhancement effect of digital and intelligent transformation on green total factor productivity is more obvious in large cities,cities with high innovation endowment,and key cities for environmental protection. On this basis,coordinated efforts should be made from three aspects:strengthening the strategic status of digital and intelligent "new infrastructure",further promoting the in-depth integration of the real economy and digital economy,and accelerating the cultivation of the innovation system,so as to provide strong support for driving high-quality development and realizing the dual leap of economic benefits and green benefits.
