Global efficiency estimation of complex networks and regional technological and economic development based on fractal network model

Abstract

Abstract To accelerate the construction of transportation infrastructure, vigorously develop the transportation industry, drive economic development, and stimulate the growth of the national economy, the author puts forward the research on the relationship between highway traffic networks and regional economic development based on the fractal network model. Taking the road traffic network of 17 prefecture-level cities in A province as the research object, the fractal dimension of each grade of the road network is calculated with fractal technology, and the weight dimension model for measuring the comprehensive road network is constructed. The empirical results show that the fractal dimension of the regional road network is affected by the size of the road network, and then the prefecture-level cities are zoned, the correlation analysis is made on the road network weight dimension, trunk line fractal dimension and comprehensive economic index of various regions. The study found that the fractal dimension of the road network in each city was positively correlated with the comprehensive economic index, indicating that the more uniform the road network coverage, the more complex the traffic network, the better the economic development of the region. In order to further explore the coordination between highway construction and economic development in each city, the fractal dimension of 17 prefecture-level cities is calculated by introducing the fractal model of highway scale and economic output, it is found that the economic development of 6 cities including 1 city is ahead of the highway scale, 4 cities including 4 are the same, and the economic development of 7 cities including 2 cities lags behind the highway construction scale. Although the weight dimension does not represent there present your state of all classes of highways in a spatial form, it is based on the spatial fractal of all classes of highways, the weight value of the road capacity is integrated, which can highlight the advantages in the horizontal comparison with the fractal situation of the comprehensive road network in the same level areas.
