【摘要】：当今时代消费者受到信息和技术不断更新和发展的影响,生活需求变得复杂、不稳定和多元化;另一方面,企业同样受到来自消费者和竞争对手反应的影响,因此所做的战略决策实际上是在模糊的市场环境下进行的。本研究基于模糊数学、博弈论和企业竞争战略决策理论,对市场容量进行模糊化,构建模糊博弈模型,并在此基础上分析企业竞争战略决策现象,为企业市场竞争提供相关解释和启示。第一,构建了区间相同的模糊市场容量古诺模型,重点分析企业超额利润获得。通过建立模糊市场容量估计函数,企业可以根据自身的乐观程度在相同的模糊市场容量区间内估计模糊市场容量,并以有限理性进行产量决策。从模型方面看,该模型扩展了经典古诺模型的均衡数量,经典古诺均衡成为它的特例;从实际产量竞争决策方面看,企业获得超额利润需要比竞争对手更乐观的市场容量估计,在这种情形下企业对自己的产品更有自信。第二,构建了区间差异的模糊市场容量古诺模型,重点分析企业市场进入退出策略和市场定位。该模型改进了第一个模型,假设企业对模糊市场容量区间的估计存在差异性,企业进行估计和决策前需要首先通过模糊市场容量区间估计函数确定好各自的市场容量区间,分析模糊市场容量反应函数发现,潜在进入者需要在进入前调查清楚在位企业的实力和模糊市场容量的匹配程度;处于产量劣势的追随者需要紧跟市场领导者的步伐,注重产品质量;企业需要坚持产品创新,扩大市场容量。第三,构建了模糊市场容量伯川德模型,从模糊市场容量的角度对伯川德悖论给出新的解释。通过分析模糊市场容量条件下企业进行价格战的过程以及模糊市场容量伯川德均衡,发现企业基于模糊市场容量的竞争价格要高于边际成本且具有不相同的正利润。因此从模糊市场容量的角度对伯川德悖论和价格战进行新的解释。并为防止企业过度竞争给出了相关解释和启示。
[Abstract]:Nowadays, consumers are affected by the continuous updating and development of information and technology, and the needs of life become complex, unstable and diversified. On the other hand, firms are also affected by reactions from consumers and competitors, so strategic decisions are actually made in a fuzzy market environment. This study is based on fuzzy mathematics. On the basis of game theory and enterprise competitive strategic decision theory, the market capacity is fuzzy and the fuzzy game model is constructed, and on this basis, the phenomenon of enterprise competitive strategic decision is analyzed. To provide relevant explanations and revelations for the enterprise market competition. First, the paper constructs a Cournot model of fuzzy market capacity with the same interval, focuses on the analysis of the excess profits of enterprises. Through the establishment of fuzzy market capacity estimation function. Enterprises can estimate fuzzy market capacity in the same range of fuzzy market capacity according to their own optimistic degree, and make output decision with limited rationality. This model extends the equilibrium quantity of classical Cournot model, and the classical Cournot equilibrium becomes its special case. From the point of view of actual production competition decision, enterprises need more optimistic market capacity estimation than competitors to obtain excess profits. In this case, enterprises have more confidence in their own products. Second. In this paper, a fuzzy market capacity model with interval difference is constructed, which focuses on the analysis of market entry and exit strategy and market positioning. The model improves the first model. Assuming that there is a difference in the estimation of the fuzzy market capacity interval, enterprises need to determine their market capacity interval through the fuzzy market capacity interval estimation function before making the estimation and decision-making. By analyzing the response function of fuzzy market capacity, it is found that the potential entrant needs to investigate clearly the matching degree between the strength of the incumbent enterprise and the fuzzy market capacity before entering. Followers at a productivity disadvantage need to keep pace with market leaders and focus on product quality; Enterprises need to adhere to product innovation and expand market capacity. Thirdly, a fuzzy market capacity Bertrand model is constructed. This paper gives a new explanation to Bertrand's paradox from the point of view of fuzzy market capacity. By analyzing the process of price war under the condition of fuzzy market capacity and the Bertrand equilibrium of fuzzy market capacity. It is found that the competitive price based on the fuzzy market capacity is higher than the marginal cost and has different positive profits. Therefore, this paper gives a new explanation of Bertrand's paradox and price war from the angle of fuzzy market capacity. Excessive competition gives the relevant explanation and enlightenment.
