Abstract Following the rule of complete set and small intersection redundancy, the paper redivides 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 secrets; technological secrets have supportive effects on the efficacy of IPRs, lead time as well as superior complementary assets; lead time improves the efficacy of superior complementary assets and superior complementary assets enhances the efficacy of IPRs, technological secrets as well as lead time.
