基于風(fēng)險(xiǎn)偏好的航運(yùn)公司多元化投資組合決策研究
[Abstract]:With the development and maturity of investment behavior decision theory, researchers pay more and more attention to the importance of non-economic factors in decision making. In particular, the representative risk preference factors in the human factor affect the decision-making results. The investment decision of a single investment project includes people's risk preference in the decision-making factors. With the maturity of single investment research, people begin to take risk preference into account in studies with multiple portfolios. The shipping field also appeared successively to consider the decision maker's risk attitude investment decision. On the basis of comprehensive analysis of the strategic development and development model of shipping companies, when considering the problem of portfolio decision, the decision makers with different risk preferences will take different decision action schemes for the portfolio schemes. In this paper, the decision makers with different risk preferences are faced with more complex portfolio investment, which can be used as a reference for different risk preference decision makers by constructing a decision model to work out the appropriate portfolio scheme for different risk preference decision makers. Firstly, the paper systematically analyzes the current situation of shipping companies' diversified investment decision and the deficiency of diversified investment decision, as well as the risk of shipping enterprise's diversified investment portfolio, and summarizes the influencing factors of risk decision and the influence position of risk preference on decision-making. The portfolio theory based on risk preference is put forward and the model is established. Secondly, the utility function which describes the risk preference of decision makers is combined with the mean-variance model to establish the risk aversion and risk preference portfolio decision models respectively. Through empirical calculation and analysis, the decision results of people with different risk attitudes are obtained and compared with the results of portfolio calculation without considering risk attitude, and the reasonableness of decision making ideas is verified by data analysis.
