A Decision Engineering Method to Identify the Competitive Effects of Working Capital: A Neural Network Model*

Enterprise working capital management determines the enterprise market competition efficiency and management efficiency to a great extent, how to configure working capital and make it generate a positive impact on the market competition effect in financial engineering is worth further discussion. This paper from turnover capacity and liquidity two aspects analyze the effects of working capital on engineering product market competition performance in manufacture industry. Research found that enterprise working capital turnover ability has positive effect on product market competition performance while enterprise working capital liquidity has a negatively relationship with market competition performance. Linear regression based on dynamic panel data, examined the impact of working capital on competitive performance. But according to the regression equation to predict the competitive effects of working capital, exists larger error, because the actual impact of working capital on competitive performance may be nonlinear. So we use BP neural network model to predict the competition performance, and the results indicate the overall prediction effect is good. © 2010 Published by Elsevier Ltd.
