Abstract
To determine the influence of the weight of the economic effectiveness evaluation criteria of the major investments of listed enterprises, and provide new management ideas for the development of the follow-up enterprises, firstly, the financial benefit evaluation system of investment projects is analyzed and constructed, and the specific evaluation process is analyzed. Then, on this basis, the evaluation index is refined; the basic structure of BP neural network (BPNN) is introduced, and genetic algorithm is used to improve BP neural network. The cost-benefit analysis model is constructed based on the improved BPNN. The listed company A is taken as an example to analyze its development data in recent years, and then the data of 10 listed companies are taken as the research object. Matlab simulation software is used to train and verify the improved BPNN model, analyze and predict the weight value of the financial benefit index of the investment projects of these 10 companies, and then determine the index to improve the financial benefit of the investment projects. Under the analysis of the development data of listed company A in the past 10 years, it is found that the indicators of the listed company's profitability per share, debt risk operation ability, development, and growth ability in the past 10 years are in relatively stable state. The principal component analysis of its 20 secondary sub-indexes is conducted based on the four primary indicators: profitability, debt risk, operational capacity, and development and growth. A total of eight principal components including return on equity (ROE), return on assets (ROA), (total asset turnover) TATO, turnover of account receivable (AR), asset-liability ratio, interest protection multiple, income growth rate, and year-on-year rate of increase for complete assets are extracted. The average error between the final output value, the actual value, and the expected value is 0.0304 and 0.0169, respectively. The weight coefficient of the monetary benefits evaluation indicator of investment items is calculated, and the computed results show that year-on-year rate of increase for complete assets, TOTA, ROA, turnover of total capital, and ROE are important indexes in the financial benefit evaluation of investment projects. It indicates that to improve the financial benefit of investment projects of listed enterprises, it is necessary to enhance the year-over-year growth degree of total properties and ROA.
Highlights
With the continuous construction and progress of socialist economic market in China, economic subjects in different fields and industries are cautious and focus on the investment projects they chose
The economic cycle, international financial shocks, and various economic policies are included in the macroeconomic factors; the performance of enterprises, assets, and industries are contained in microeconomic factors; supply and demand, trading system, and investors are incorporated in market factors [3,4]
The results show that 2 principal component factors with characteristic roots greater than 1 (TATO and turnover of account receivable (AR)) were extracted from the asset operation index, and 2 principal component limitations with trait roots greater than 1 were achieved from the debt risk index
Summary
With the continuous construction and progress of socialist economic market in China, economic subjects in different fields and industries are cautious and focus on the investment projects they chose. Extensive attention and researches are attracted by the evaluation of financial benefits of projects after investment [1]. Through the analysis of the indicators that affect the financial benefit of investment projects, the methods of enterprise management are better grasped, and the maximum economic benefit is brought. Investment project is a very large and complex system, with many people involved, and it will be affected by other factors besides market law [5]. Artificial neural network model has great research significance and promotion value in investment benefit prediction
