摘 要:国际间的技术扩散通过进口贸易这一形式作为一个重要的溢出渠道,其效果已经越来越显着 我国的进口贸易通过国。外研发的投入,极大地促进了新技术的流动和知识的传播 通过利用。Lichtenberg & Potterie 模型并加入人力资本因素对模型改进后发现,国内研发投入对我国全要素生产率的作用一般,国外研发投入对提高我国全要素生产率有明显的作用。 关键词:技术溢出;全要素生产率;LP 模型 Abstract: International technology diffusion through the import trade as an important form of the spillover channels, the effect has been more significant
By China's import trade through foreign investment in R&D, new technology has greatly promoted the flow and the dissemination of knowledge
This paper uses Lichtenberg & Potterie model to deal with the dataes, proves that the foreign investment in R&D significantly improve total factor productivity(TFP), and inspects the domestic R&D to the role of China's total factor productivity in general, and the end, put forward a proposal
