中文摘要：

遵循并集完备且交集冗余小的原则，重新划分了专有化手段类别；基于220家中国制造业企业产品创新的经验数据，利用多元回归分析探索并验证了专有化手段间的排斥性和支持性。研究发现，知识产权法律保护与技术知识的隐性属性之间互有排斥性；知识产权法律保护促进技术保密的有效性；技术保密提升知识产权法律保护、领先时间以及互补资产优势的有效性；领先时间促进互补资产优势的有效性；互补资产优势提升知识产权法律保护、技术保密以及领先时间的有效性。

英文摘要：

Following the rule of complete set and small intersection redundancy, the paper rediv- ides the categories of appropriability methods. Based on the data of 220 Chinese manufacturing firms who conduct product innovations, this paper explores and examines the contradictive and supportive effects among appropriability methods by use of multivariate regression analysis. The research results show that there are contradictive effects between Intellectual Property Rights（IPRs） and tacitness of technological knowledge, while IPRs exerts a supportive effect on the efficacy of technological se- crets; technological secrets have supportive effects on the efficacy of IPRs, lead time as well as superi- or complementary assets; lead time improves the efficacy of superior complementary assets and superi- or complementary assets enhances the efficacy of IPRs, technological secrets as well as lead time.
