技术获取作为众多企业选择建立战略联盟的重要原因，促进了企业创新绩效的提升。然而，技术获取的联盟动机对企业创新产出的影响却是一个极为复杂的作用过程。本文以已有研究为基础，引入专利策略构建“技术获取一专利策略选择一创新绩效”的分析框架，考察技术获取的联盟动机如何借助专利策略选择作用于企业创新绩效。选取信息技术产业的联盟企业作为样本，通过实证研究发现：技术获取动机会引致企业专利策略组合的运用，实现了技术获取向创新绩效的转化；技术获取引致的企业创新绩效因联盟意图及策略组合而存在差异，以市场进入为目标的情形下，企业创新效率和专利产出趋于增加；以市场拓展为诉求的联盟企业市值得到强化。

英文摘要：

Technology acquisition is one of the most important reasons why most firms choose to establish or participate in strate- gic alliances, which greatly enhance firms＇ innovative performance. However, the influencing mechanism of firms＇ technology acquisition to innovative outputs is rather a complex process. Based on existing researches, this paper brings patent strategies to construct the analytical framework of ＂technology acquisition - choice of patent strategy - innovative performance＂, in hope to in- vestigate how technology acquisition affects the choice of patent strategies, and their mutual effects on firms＇ innovative perform- ance. Taken firms attending IT industry strategic alliances as samples, we find that： alliance motivation of technology acquisition lead the firms to choose and implement a certain combination of patent strategies, which then enhance the transformation from technology acquisition to innovative performance, although innovative performance differs according to the alliance motivation and the strategic combination. Set market access as the performance goal, both firms ＇ innovative efficiency and patent outputs tend to increase, while when attempting to market extension, market capitalization or market opportunity would be consolidated.
