摘要
基于2009—2018年中国上市企业面板数据和通过Python爬虫和文本挖掘技术获得的企业微观数据,本文实证检验国际合作研发对企业科技成果转化的影响效应及中间作用机制。研究结果表明:①企业参与国际合作研发能显著提高其科技成果转化效率;②异质性分析表明,企业国际合作研发对科技成果转化效率的促进效应因企业合作研发模式、科技属性和行业特征而有所差异;③机制研究发现,创新质量提升是企业国际合作研发促进科技成果转化效率的重要中介渠道。区分知识创新和产品创新的转化效率后,科技成果内部存在从知识创新到产品创新的二次转化效应。不同于已有文献较多关注影响企业科技成果转化外部因素,本文从创新质量这一内部视角解释国际合作研发助推科技成果转化的重要原因,具有一定的理论和应用价值。
Based on the panel data of Chinese listed companies from 2009 to 2018 and the micro database constructed by Python crawler and text mining technology, this paper empirically examines the effect and intermediate mechanism of international cooperative R&D on the transformation of enterprises’ scientific and technological achievements.The results show the followings.①Firms’ participation in international cooperative R&D can significantly improve the transformation of scientific and technological achievements.②Heterogeneity analysis shows that the effect of international cooperative R&D on the efficiency of transformation differs according to different cooperative modes, properties of technology and industry characteristics.③Based on the mechanism research, it is found that the improvement of innovation quality is an important intermediary channel for enterprises’ international cooperative R&D to promote the efficiency of scientific and technological achievement transformation.After distinguishing the transformation efficiency of knowledge innovation and product innovation, it shows that secondary transformation effect exists from knowledge innovation to product innovation.Different from the existing literatures that focus more on the external factors affecting the transformation of scientific and technological achievements, this paper explains why international cooperative R&D boosts the transformation of scientific and technological achievements from the internal perspective of innovation quality, which has certain theoretical and application value.
