【摘要】：目前,我国可耗竭资源开采回采率普遍较低,企业可以通过追加投资来提高资源的管理及技术水平,进而提高资源开采回采率,减少资源浪费。文中基于Hotelling横向差异化模型,构建了一个三阶段动态博弈模型,采用逆向归纳法的思路,分析了可耗竭资源开采企业追加投资的动态行为。首先在企业通过竞争形成的价格和市场份额给定的基础上,分析第三阶段实行价格歧视消费者的转移情况,得到两企业的竞争策略;接着将第三阶段的最优价格策略和利润考虑到第二阶段中,讨论两企业的价格竞争均衡问题,分别得到两企业的需求;最后将第二阶段的利润贴现到第一阶段,可得到企业追加投资的策略,给出了该动态博弈模型存在唯一子博弈完美纳什均衡的条件和企业最佳追加投资规模。研究结果表明,要使企业追加投资就必须要求追加投资的回报率足够高,当企业追加投资的回报率很高时,只要较小的追加投入就会产生较大的边际成本减少量,获得较大的竞争优势,甚至会将不进行追加投资企业挤出市场;当投资回报率给定时,企业追加投资的激励是取决于其耐心,即企业对未来收益关注越多,则追加投资的规模也越大。
[Abstract]:At present, the recovery rate of exhausted resources in our country is generally low. Enterprises can improve the management and technical level of resources through additional investment, and then improve the recovery rate of resource exploitation and reduce the waste of resources. Based on the horizontal differentiation model of Hotelling, a three-stage dynamic game model is constructed, and the dynamic behavior of additional investment of exhausted resource mining enterprises is analyzed by using the idea of reverse induction. Firstly, on the basis of the price and market share given by the enterprise through competition, this paper analyzes the transfer of price discrimination against consumers in the third stage, and obtains the competitive strategy of the two enterprises. Then, the optimal price strategy and profit of the third stage are taken into account in the second stage, and the equilibrium problem of price competition between the two enterprises is discussed, and the demand of the two enterprises is obtained respectively. Finally, the profit discount of the second stage is realized to the first stage. The strategy of enterprise supplementary investment can be obtained, and the conditions for the existence of a perfect Nash equilibrium in the dynamic game model and the optimal additional investment scale of the firm are given. The results show that in order for the enterprise to make additional investment, the return on additional investment must be high enough. When the rate of return on additional investment is very high, a larger marginal cost reduction will occur if the additional investment is small. To gain a greater competitive advantage, firms that do not make additional investments will even be squeezed out of the market; when the rate of return on investment is given, the incentive for companies to make additional investments depends on their patience, that is, the more attention they pay to future returns, The larger the additional investment.
