Abstract: China is a country with the fastest growing high-speed railway, which is radically changing peoples commuting and travelling patterns, as well as promoting urbanization by reshaping urban spatial patterns in China. However, wide disputes exist in the role of high-speed railway in driving China's urbanization. This paper explores urban spatial patterns and the role of high-speed railway at China's prefecture level over 2010-2016 using MODIS remote sensing data and spatial panel analysis. The results suggest that there is an increasing tendency of urban agglomeration, and the Yangzi River Delta Region has witnessed the most rapid pace of urbanization. The impact of high-speed railway on urbanization depends on the development level of the city and the location of the highspeed railway station. High-speed railway significantly enhances the speed of urbanization with a larger effect in medium and small cities.

摘要： 中国是当前世界上高速铁路发展速度最快的国家。高铁作为一项大型的交通基础设施，不仅深刻改变了人们的出行方式，更发挥了重塑城市空间和推动城镇化发展的作用。基于MODIS遥感数据考察在2010~2016年中国高速铁路快速发展时期，中国297个地级市的城镇化空间分布格局及其变化趋势，并采用空间面板回归的方法探讨高铁站点的开通对城镇化发展的影响。结果表明在高速铁路快速发展时期，中国的城镇化发展格局空间集聚特征日益明显，长三角地区是城镇化发展最快的区域；高铁对城镇化的推动作用会根据城市本身的发展水平及高铁站点的位置而产生分化；高铁站点的开通可以显著提高其站点所在城市的城镇化发展速度，而对城镇化的推动作用在中小规模城市中更为明显。
