In this work, the index system of the information technology industry in private enterprises is established, which includes six aspects: Profitability, operation ability, solvency, expansion ability, innovation ability, and company scale. Then, the GA-BP algorithm combining genetic algorithm and neural network is introduced to analyze and predict the growth of the enterprise. After preprocessing the data gained from Wind dataset, the model is trained and the coefficient of determination R2 on the test set is 0.9997, showing its outperformance than other five machine learning algorithms. Through the correlation coefficient analysis between the growth rate of market value and the growth value predicted, the validity of the established model is tested. Finally, the index system is simplified by ranking the importance of the features via Random Forest Algorithm. The coefficient of determination R2 on the test set is 0.8929 when eight features are selected, proving the rationality of the initial index selection again.
