Abstract According to the “Long Term Plan of Railway Network”, this paper selects accessibility and economic contact intensity as indicators to analyze how their mean, coefficient of variation and standard deviation will change after the high-speed railway network’s completion in 2020, and tries to reveal the impacts of high-speed railway on the change of economic contacts between the cities along the route. The results show that, under the influence of high-speed railway, although the economic contacts of different high-speed railways present space differentiation in changes during 2011 to 2020, the economic contact intensities of the cities along the “four vertical and four horizontal” high-speed railways and hub cities all have increased obviously along with the improvement of their accessibilities. In this way, it is beneficial for the business interconnection between the cities along the high-speed railway, help promote the progress of regional integration and form significant economic belt nationwide. Therefore, the state government should take measures accordingly to use this kind of change to advance the coordinated development of regional economies and control the negative effects that may happen.
