Abstract:

A transportation hub is the key link in the construction of the comprehensive three-dimensional transportation corridor of the Yangtze River Economic Belt (YREB), and it is the basic factor responsible for the promotion of this belt. A high-speed railway hub has the effect of "last kilometer of time-space compression" and is the key to building an efficient, convenient, modern, and comprehensive transportation system. Based on the principle of this effect, this study constructed a model for measuring the connection-distribution performance of the high-speed railway hub, determined the connection-distribution performance of the urban high-speed railway hub in the YREB, and analyzed its spatial differentiation characteristics, and further revealed the influencing mechanism of the connection-distribution performance of the high-speed railway hub. The main results are as follows: (1) the connection-distribution performance of the high-speed railway hub in the YREB presented an "olive type" grade structure with two small ends and a large middle section, that is, there are fewer high-speed railway stations with high performance and average performance, and there are more high-speed railway stations with good performance and medium performance. (2) The connection-distribution performance of the high-speed railway hub in this economic belt showed a regional differentiation pattern of "high in the east and low in the west" and "high in the north and low in the south", and showed an urban agglomeration differentiation pattern of "high in the core area and low in the marginal area". Moreover, spatial differences were prominent in the distribution of nine evaluation indexes of the connection-distribution performance of the high-speed railway hub. (3) GDP, urbanization rate, city level, station passenger flow and frequency of shuttle bus were key driving factors affecting the connection-distribution performance of the high-speed railway hub. At the same time, there were significant differences in the key driving factors for the connection-distribution performance grades of high-quality, good, medium and average levels.

Key words: high-speed railway hub, performance evaluation of the connection-distribution, spatial differentiation, mechanism, Yangtze River Economic Belt
