摘要:文章以2014年“宽带中国”战略实施为准自然实验,利用多期双重差分法研究了数字基础设施建设对城市绿色全要素生产率的影响。研究发现:数字基础设施建设有利于促进城市绿色全要素生产率的提升,且该作用是通过提高城市技术创新水平和产业结构优化来实现的。研究结果为推动我国经济高质量发展,合理优化数字基础设施建设,促进城市绿色全要素生产率提高提供了理论支撑和政策建议。
Abstract: Based on the implementation of the "Broadband China" strategy in 2014, this paper uses the multi-period double difference method to study the impact of digital infrastructure construction on urban green total factor productivity. It is found that the construction of digital infrastructure is conducive to promoting the improvement of urban green total factor productivity. And this role is achieved by improving the level of urban technological innovation and industrial structure optimization. The research results provide theoretical support and policy suggestions for promoting the high-quality development of China's economy, reasonably optimizing the construction of digital infrastructure, and promoting the improvement of urban green total factor productivity.
