This article describes the economic development forecast problems often encountered in macroeconomics. Taking the Zhejiang Province modernization index as an example, this paper uses the BP neural network method to establish the economic system model of Zhejiang Province and predicts the economic situation in the following years based on these models. Specific description of the above system design ideas, specific programs, algorithms and implementation and other issues. Through the above examples, illustrate the general method and application of neural network in practice.
