| 摘 要： | 在技术位势的测度基础上，区分低位势企业-高位势学研机构、高位势企业-低位势学研机构两种类别，构建混合回归模型及个体效应模型，运用我国制药企业1995-2012年的产学研联合发明专利数据，对不同类别组合和同一类组合内不同影响时期技术势差对企业技术能力的影响效应进行了比较研究。结果表明，产学研合作中企业技术能力成长的短期效果显著优于长期效果，而合作主体双方技术势差对企业技术能力成长存在长短期上的异质性，并受到双方相对技术位势关系的调节。在低位势企业-高位势学研机构合作中，技术势差有利于促进企业技术能力的成长，其中短期效应达到显著；在高位势企业-低位势学研机构合作中，逆向技术势差的存在会显著抑制企业技术能力的长期成长。

The long-term and short-term effect of technological potential difference on enterprises,technological capacity: Empirical evidence from industry-university-research patents |
| |
| Abstract: | This paper contributed to identifying two types of university-industry cooperation in which enterprises partnered with universities or research institutions of lower and higher technological potency. Empirically, the heterogeneous effects of technological potential difference on an enterprise`s technological capacity growth based on that two cooperative statuses were fully studied and further explored from the perspectives of long run and short run through mix model and individual effect model of regression with pharmaceutical university-industry invention patents during 1995-2012 in Derwent database. Results showed that enterprises` growth of technological capacity in short term significantly outweighed that in the long term. Further, as to an enterprise innovating with higher-potency universities or research institutes, the technological potential difference promoted corresponding technological growth of enterprise especially in the short term with statistical significance. Comparatively, consortia with lower-potency academic partners enabled bidirectional knowledge flows, but existence of the potential difference significantly inhibited enterprises from growing their technological capacities in the long term. |
