圍繞bertrand悖論的所展開的爭論,為進一步展開對這一問題的分析提供了豐富的工具和背景知識,在對已有的理論文獻加以回顧引述的基礎上,保留原有的空間壟斷概念和競爭策略的同時,改變單純從生產者角度來論述產品差異度對企業合作的影響,重新構造消費者效用函數,引入消費者偏好,以消費者的偏好的大小來表示產品之間的差異度,通過單時期和無限期博弈模型來論證產品差異度(消費者偏好程度之比)對臨界折現因子的影響,進而論證其對企業間進行合作所產生影響;效用函數的引入使得價格和運輸成本不再是決定消費者購買的唯一因素,消費者對產品的選擇不完全取決于消費者的位置,這會導致企業間定價和市場份額的非對稱性變化。Through the analysis, it is shown that : 1, while fabricating the grating, the principle of selecting the parameters is : the period should be as large as possible, the etching depth should be small and filling factor should approach to 0. 25. 2, if selecting the parameter combine the selecting principle and the requirement of concrete application, the space of selecting the parameter should be larger than before. 3, while the period to. 4a, the surface profile has no effect on the reflectivity
