Abstract：Based on the background of the new crown pneumonia epidemic,this paper uses the grey system theory to establish a short-term dynamic prediction model of economic indicators in the Yangtze River Delta region.Compared with the existing gray model,the use of Euler polynomials as the driving term of the gray model makes the new model more flexible and versatile.The mod-el exhibits more significant penformance and more accurate stability in economic forecast in the Yangtze River Delta region.The in-novation of this paper is to analyze the dynamic forecast of the GDP of each city in the Yangtze River Delta in 2022 under the influ-ence of different epidemic levels,and combine the historical data of the GDP of the cities in the Yangtze River Delta to predict the GDP in 2022.The value can reach up to 130 trillion yuan.
