基于模糊理論的港口投資風險分析方法研究
[Abstract]:In the national economy development and construction, the port plays a pivotal role. Strengthening port construction is the main content of improving the overall strength of the country. At the same time, the port construction project has the characteristics of large investment and high technology content, which will inevitably meet various risks in the course of port construction. Therefore, port investors, such as banks, take the risk analysis of port construction as the key research content. It is found that the risks of port construction are various. Due to the changes of natural conditions, geological structure and construction scale, there are a lot of uncertain factors in the process of port construction. These uncertainties often lead to large budget overruns, and may even lead to project failure. Therefore, it is very necessary to carry on the effective risk analysis to the port construction project investment. On the basis of consulting a large number of literatures and existing achievements, this paper firstly makes a systematic and in-depth study on the present situation of port construction risk management at home and abroad. Secondly, from the point of view of technical economics, taking the internal rate of return as the evaluation index of risk variables, the economic evaluation and uncertainty analysis of port construction projects are carried out. Thirdly, the sensitivity coefficient of uncertain factors is taken as the weight measure of risk variable factors, and the first-degree fuzzy evaluation model of project investment risk is established, and the accuracy of expert subjective evaluation is taken as the weight of each evaluator. A two-level fuzzy evaluation model of port construction investment risk is constructed. Finally, the feasibility and practicability of the improved fuzzy comprehensive evaluation model are verified by taking the construction project of Haihong Port in Dalian Port as an example. In this paper, the improved fuzzy comprehensive evaluation method is applied to the investment decision of port construction project, which makes the evaluation of investment risk of port construction project realize quantitative, and it is more convenient to analyze and judge, which can reduce the investment risk of port construction project. Expand economic benefit, have important realistic meaning and use value.
