为了探索产业特性、内部研发活动、创新策略和知识属性对多元化产学研知识互动的影响，本文对广东省清溪镇所有规模以上企业进行调研，获得了166家企业参与14种产学研知识互动情况的数据。根据现有研究，本文将多元化产学研知识互动形式分为合作研究、人员流动、研究服务与支持和科研成果商业化四类。研究结果表明，高技术产业在人员流动、研究服务与支持和科研成果商业化上的参与程度比非高技术产业高，但在合作研究上两者并无差异。企业内部研发活动和探索型创新策略对四类产学研知识互动的程度都有正向影响。另外，企业所需知识的属性也会影响企业参与多元化的产学研知识互动。

The aim of this paper is to examine the effects of sectoral characteristics, in-house R&D activities, innovation strategies and nature of knowledge on firms’ engagement in varied knowledge interactions. Based on a survey of all above-scale manufacturing firms at Qingxi Town of Dongguan City, Guangdong Province, we gathered data on 14 university-industry-research institution knowledge interaction channels used by a sample of 166 manufacturing firms. We distinguish four types of knowledge interaction channels, namely collaborative R&D, human mobility, R&D services and support and commercialization of research results . The findings show that firms in high-tech industries engage more deeply in human mobility, R&D support and services and commercialization of research results channels than those in non-high-tech industries, but there is no difference between the two sectors in collaborative R&D channels. Besides, the results show that there are positive correlations between the four channels and in-house R&D and explorative innovation strategy. At last, we find that nature of knowledge acquired from external sources can influence the propensity of firms to engage diversified channels.
