GDP Forecast of Jinan and Hefei based on LSTM and the Transformation Enlightenment of Old Industrial City Jinan

Jinan City, Shandong Province, is one of the important cities in modern industrial production and development in China. It plays an important role in the industrial history of modern China and has a very rich industrial cultural heritage. Hefei City, Anhui Province, from a small city, through reform and innovation, has become a rising star of Chinese cities, with per capita GDP approaching Jinan. In this paper, the single variable time series prediction model based on LSTM is used to fit the Area GDP of Jinan and Hefei in 31 years from 1990 to 2020, and the Area GDP data of the two cities in the next three years is predicted. Finally, combined with the development of foreign old industrial cities, this paper puts forward some suggestions for the future development of Jinan.
