Forecast the Development Scale of Key Industries Based on the Improved GM(1,N) Model and the Research on High-quality Synergistic Development

High-quality development is the primary task of comprehensively building a socialist modernized country. Based on the current situation faced by different industries in terms of high-quality development space, development environment and development connotation, it is urgent to clarify the demands and trends of high-quality development of key industries. Therefore, In this paper, Pearson correlation coefficient method is used to analyze the correlation between the power grid and the high-quality influencing factors system of key industries. By constructing the gray prediction model GM(1,N), the development scale and development trend of key industries in Jiangsu Province from 2025 to 2030 are predicted. The interactive mechanism of high-quality synergistic development is constructed. The results show that the coupling between key industries is strong. For some high-energy-consuming industries, the product output and power generation decline is large and tends to flatten out. In the long run, the synergistic development between the government, the grid enterprise and the key industries can help to realize a win-win situation for the economy, the environment and the society.
