Abstract

With the development of the economy, developing high-technology industries and upgrading traditional industries have become a global focus. The relationship between the development of high-technology and traditional industries has also affected urban expansion. In this paper, a fractional derivative gray Lotka−Volterra model with time delay (FDGLV) is established by introducing fractional derivative and delay factor into the GLV model. The model is solved by using the fractional Adams−Bashforth−Moulton predictor−corrector algorithm. The gray correlation analysis is used to determine the time delay value of the model, and the parameters are optimized by using the whale algorithm. Then, the data of high-technology industry, traditional industry, and urban expansion in Chengdu, Changsha, and Chongqing are collected to verify the effectiveness of the model. Finally, the model is used to analyze the coopetition between industrial upgrading and urban expansion in Wuhan, and predict the development status in the next 5 years.
