Comparative Study on the Development Level of China’s Transportation Infrastructure

Abstract

In order to study the development status of China’s transportation infrastructure and regional development differences and to determine how to do a better job in transportation development planning, transportation investment and construction, traffic operation and maintenance, the simple and intuitive weighted sum method was used to construct an evaluation model of the development level of the transportation infrastructure. The evaluation index system of the development level was also established. The comprehensive weight of the indexes was determined by combining the improved G1 method, the antientropy method, and the optimal combination method based on the consistency test group decision-weighting method. The advantages of the evaluation method constructed in this paper compared with the traditional method, the overall development status of China’s transportation infrastructure, the relative development status among regions, and the main manifestations of the imbalance are analyzed. The results show the following. (1) Compared with the entropy method, the antientropy weight method can avoid the extreme value and compared with G1 method, the improved G1 method can avoid losing effective information and amplify invalid information. The optimal-combination method can synthesize the subjective and objective factors well, making the comprehensive weight more scientific and accurate. (2) The comprehensive index of transportation infrastructure development level in western, central, and eastern China showed a steady upward trend, but the regional difference was obvious, showing a spatial distribution pattern of high in the east and low in the west, indicating the unbalanced development among regions. (3) From 2014 to 2018, the average annual growth rate of the development level of transportation infrastructure in eastern China was higher than that in western and central China, indicating that the imbalance among the western, central, and eastern regions was still worsening. (4) Through the comprehensive index analysis of the criterion layer, it is found that the imbalance of the development of transportation infrastructure is mainly manifested in the development scale, transportation level, and growth potential. The evaluation results are in line with the actual situation and can provide some enlightenment for the planning, investment, and construction of China’s transportation infrastructure.
