本文以中国本土企业为研究对象, 依据中国国家知识产权局专利许可备案登记数据、专利申请数据和中国工业企业数据, 采取Tobit模型实证分析了2002-2005年间181家企业专利技术引进与其技术多元化发展的关系。研究表明, 企业跨技术领域引进技术对其技术多元化发展存在消极作用;与国内技术许可引进相比, 引进国外技术可以带来对技术多元化发展的积极效应;企业许可引进的相对技术年龄与其技术多元化发展之间存在倒U型关系。

This study is determined to explore the technological diversification phenomenon through technology licensing-ins pertaining to Chinese indigenous firms. Various data sources are used in the empirical analyses of 181 Chinese home-grown firms which are engaged in technology licensing-in activities during 2000-2005, i.e. the registered records of patent technology licensing agreements and patent applications by the State Intellectual Property Office of the People's Republic of China, and the annual survey of all Large- and Medium-scale companies by the National Bureau of Statistics. Through a Tobit model in the statistic analyses, it has been found that: (1) technology licensing-ins across a wider technology domain negatively impact licensee firms' subsequent technological diversification development; (2) technology licensing-ins across a longer geography distance, i.e. from advanced economies positively influence licensee firms' subsequent technological diversification development; (3) licensed-in technologies from a relative longer temporal distance exhibit a reverse "U" relationship with licensee firms' subsequent technological diversification development.
