中文摘要：

本文以1997—2015年中国各省的面板数据为样本,实证检验了各省进口贸易的国际研发溢出及知识产权保护水平对全要素生产率及其分解效应的影响,并控制了各省研发资本、研发人员的投入。实证结果表明,进口贸易的国际研发溢出对各省的全要素生产率有明显的促进作用,尤其是资本品的进口。国内研发资本只对技术进步有显著的正向影响,研发人员越多越能带来技术效率的改善。分区域的回归结果表明,进口贸易的研发外溢只对东部区域的全要素生产率和西部区域的技术进步有促进作用,中部全要素生产率的提高主要来自于本区域内的研发资本投入。各省知识产权保护水平越严格越有利于全要素生产率的增长,也能使进口贸易研发外溢资本,尤其是资本品进口贸易的研发外溢资本带动全要素生产率的提高。

英文摘要：

This paper empirically estimates the effects of international RD spillovers and the intellectual property protection（IPP） level on the total factor productivity（TFP） based on the province panel data from 1997-2015. We have controlled the effects of RD capital and RD personnel. The test results suggest that the international RD from import have a significant effect on TFP, especially the RD spillovers from the imports of capital. But the domestic RD capital can only improve the technical progress and the RD personnel can only improve the technical efficiency. The regional regression results indicate that the international RD spillovers can promote the TFP of Eastern China and the technical progress of Western China, while the increase of TFP of Central China is mainly from the RD capital of their own region. The IPP level and its interaction with international RD, especially the interaction with the international RD spillovers from capital goods imports have a positive effect on TFP.
