Abstract ：
The 4.0 technologies provide a technological window for regions to promote their innovation level and achieve leapfrogging. Using the panel data of China's cities in the period from 2004 to 2021, this study finds the significantly positive impacts of technological window in technological innovation and technological catch-up and that these impacts are amplified by knowledge spillovers. Dividing regions into complex regions and simple regions based on their knowledge complexity, the roles of technological window and knowledge spillovers show heterogeneity. Complex regions are more sensitive to utilize technological window and knowledge spillovers to accelerate innovation and catch-up, while the technological window is less efficient for simple regions and these regions are difficult to absorb frontier knowledge spillovers.

Abstract ：
高铁直通极大地促进了我国城市间要素流动，推进城市间知识溢出水平的提升，促进城市进一步发展。然而，高铁是否能够缩小城市间知识溢出差距、带动沿线城市均衡化发展仍然值得探讨。本文利用2003～2022年高铁直通和专利引用数据，构造包含80940个城市对的面板数据，考察城市间高铁直通对城市间知识溢出差距变化的影响。研究发现：高铁直通扩大了城市间知识溢出差距，知识向高发展水平城市净流出，知识要素分布的不均衡性加剧。高铁直通对知识溢出差距的影响在不同发展水平、不同地理和经济距离、不同城市群中的城市对中存在差异。本文为进一步完善高铁网络、缩小城市间知识溢出差距、促进协调发展提供政策参考。
