Investment Value Evaluation Of The Listed Companies In China Machinery

In Currently academia, for the studies of evaluation of investment projects of listed companies, the researchers mostly pay attention to the single objective to give the value. However, most of the investors pay attention to how to acquire a good objective to invest. In this article, the author studies the evaluation of the relative value to compensate for the lack of existing research. And satisfy the investors, management and other investments in acquiring targets with high investment value by providing methodological support.Based on the system sorting of home and abroad relevant literature, the author analyzed the major driver of company value, summed up the current evaluation method, and then proposed from two different angles investment value evaluation:(1) According to the value drivers, author determined the evaluation index system, and then use factor analysis to extract the main factors in the index system and to determine the weights of the main factors. After that, author used the gray fuzzy optimization model to evaluate the investment project of the machinery industry; (2) According to the driver of value, author determined the input and output index, and then used the super-efficiency model to evaluate the investment project. The research results and the contribution of this article are as followings:(1) studying how to use the grey fuzzy optimization model in evaluation of the investment project. The results show that when using this model, not only the contribution for the optimal solution, but also the effect of the couple factors is considered; (2) studying how to use the super-efficiency model to evaluate the investment value. The results show that the super-efficiency model can efficiently identify the relative investment value of the company.
