【摘要】 以上海工业企业为研究样本分析了企业自主研发和技术引进对企业绩效的不同贡献.文中将两种不同的促进技术进步策略作异质性的分析处理,同时考虑模型的选择偏差,再通过计量方法的匹配,做基于倾向得分的平均处理效应估计.研究结果显示,同不做任何技术创新与引进的企业相比,试图通过技术进步寻求发展的企业均对企业绩效产生了积极效应.其中技术引进方式对企业的当期利润和企业劳动生产率的提高更优于自主研发方式,而自主研发对于企业TFP的贡献却是大于技术引进的.研究还显示这两种技术进步方式对于不同所有制结构的企业作用不同.更多还原

【Abstract】 This study analyzed the impact of R&D and technology import on the firm performance in Shanghai.We considered R&D and technology spill-over as heterogeneous treatments and considered an econometric matching,taking a possible selection bias into account. The results show that,compared with companies without any treatment,firms that received either or both of the treatments yield positive effects.Technology import spill-over influences the firm’s profit and firm’s labor productivity more significantly while R&D was more important in improving firm’s TFP.It indicated that the positive effects induced by spillovers in technology trade and R&D activities should be fully utilized by most domestic companies in Shanghai.更多还原
