Abstract：High-speed rail, with the obvious advantages of the strong transport capacity, fast speed, safe and comfortable nature, is leading a revolution in the global transportation. The impact of the high-speed rails on the accessibility of cities and the pattern of regional economic in China has been a hot issue with Chinese high-speed rail network gradually improved. Based on the cross-sectional data of the years of 2008, 2011 and 2013, from two dimensions of the weighted average travel times of the cities along the HSRs and the hour economic circles extension of central cities, this article analyses the impact of high-speed rails on the accessibility. And further, it analyses the impact of the high-speed rails on the regional economic development pattern by the gravity model, regional superiority potential model and Moran index, Theil coefficient. This study shows that:1) High-speed rails have been significantly improving the daily accessibility of cities along the rails. The accessibility levels of eastern cities are still higher than middle and western cities. But three areas' urban transportation development imbalance has a modest improvement. The hour economic circles of Beijing and Wuhan present planar spread pattern, but the circles of Shanghai, Guangzhou and Xi'an are linear scaling. 2) High-speed rails are significantly impacting the Chinese regional economic development pattern. The accessibility levels of the cities along the rails have been improved. The economic ties between cities are more closely linked. Urban agglomeration in the middle reaches of the Yangtze River is great potential. Diffusion effect brought by high-speed rails is enhanced. Finally, this article gives the further discussion of promoting the healthy development of Chinese regional economic based on the high-speed rail construction.
