This study examines industrial transfer from the perspective of industrial chain. Firstly, the input-output method is used to identify the upstream and downstream related industries of communication equipment. Secondly, through the study of provinces that have implemented similar industrial scale development law, the key factors affecting the industrial transfer scale are established. Based on the practical experience of this province, this study constructs a multiple regression forecasting model for the scale of industrial undertaking area. This model not only incorporates the actual development situation, but also fully draws on the successful development experience of other regions, and aims to innovatively predict the possible scale of the industry in the future. This approach not only ensures the realistic feasibility of the forecast results, but also enhances its prospectivity and accuracy. Finally, through rigorous empirical analysis, the validity of the prediction model is verified. The forecast results not only provide the scientific basis for the government and enterprises to formulate the strategy of industrial chain transfer, but also provide the necessary data basis for assessing the possible environmental impact of industrial transfer.
