中文摘要：

标准化和多样化是相对的，标准化会降低产品的差异性。技术进步企业面临将技术申请法定标准实施标准化或保留技术实施差异化战略的选择。前者可以收取专利费，提高企业的利润；后者可以提高产品的内在价值，获得优于对手的竞争优势。文章将技术水平作为变量引入到产品的基本效用中改造Hotelling模型，分析了技术进步企业在标准化战略和差异化战略间的选择，得出这种选择和技术水平的关系，从而为网络效应企业的战略选择提供了理论支持。

英文摘要：

Standardization is the opposite of the differentiation and may reduce the diversity of products. A technologically advanced enterprise may face strategy choices between applying for legalizing the implementation of technology standardization and retaining the implementation of technology differentiation. The former helps to collect royalties and increase the profits of enterprises while the latter can increase the intrinsic value of products and the competitiveness of enterprises. In this paper, technical level is introduced as a variable into the basic utility of products to transform the Hotelling model. By analyzing the strategy choice between standardization and differentiation of technologically advances enterprise, we find out the relationship between strategy choice and technology level, thus providing a theoretical support for the strategy choice of enterprises under network externalities.
