Abstract: In the era of open innovation, manufacturers are increasingly relying on suppliers and other external partners in their innovation process. Based on the absorptive capacity theory and the organizational inertia theory, this paper examines the influence of diversity of technological knowledge base on the utilization of supplier innovation. The diversity of technological knowledge base can promote the innovation utilization of suppliers by improving the absorptive capacity and restrain the innovation utilization of suppliers by reducing the absorptive intention. However, there are significant differences in the mechanism and effect of supplier innovation between the diversity of technology-related and technology-independent knowledge base. The results obtained from the data of listed manufacturing companies in China show that the supplier innovation performance is positively correlated with enterprise innovation performance. The correlation between the innovation performance of suppliers and that of the enterprises is weakened by the irrelevant diversity of technological knowledge base. The correlation diversity of technological knowledge base enhances the positive correlation between the innovation performance of suppliers and that of enterprises.

Key words: supplier innovation performance, diversity of technological knowledge base, absorptive capacity, innovation performance of manufacturer

摘要： 在开放创新时代，创新越来越依赖于供应商等外部创新源。基于吸收能力理论和组织惯性理论研究了企业技术知识基础多元度对企业利用供应商创新的影响。企业技术知识基础多元度可通过提升吸收能力促进企业对供应商创新利用，也可通过降低吸收意愿抑制企业对供应商创新利用。但企业技术知识基础相关多元度和技术知识基础无关多元度影响企业利用供应商创新的机制和效果存在明显差异。 基于制造业上市公司数据进行了分析，主要结论如下：供应商创新绩效与企业创新绩效正相关；技术知识基础不相关多元度削弱了供应商创新绩效和企业创新绩效之间的正相关关系；技术知识基础相关多元度增强了供应商创新绩效和企业创新绩效间的正相关关系。
