Food Product Proliferation: A Market Structure Analysis
回顾了产品激增的定义和分析模型，并用回归模型检验市场结构与新食品产品数量之间的关系，发现产品激增是差异化寡头市场中的一种行业行为。
Abstract The frequent introduction of avowedly novel products is a common marketing strategy of leading food manufacturers. Over half of all new packaged consumer goods are foods or beverages, yet little is known about the amounts, patterns, and causes of product proliferation. Alternative definitions and analytical models of product proliferation are reviewed, focusing on those derived from Hotelling spatial‐equilibrium theory. A simple regression model is used to test the relationship of market structure to the number of new food products introduced. The results verify that food product proliferation is a mode of industry conduct arising from markets characterized by differentiated oligopoly.
