利用面板动态最小二乘法估算我国工业分行业国内研发和通过进口贸易从14个OECD国家获得的技术溢出对全要素生产率的贡献。结果表明，国内研发投入对全要素生产率的贡献不管是系数还是显著性都明显高于通过进口获得的研发溢出对全要素生产率的贡献。进一步区分资本品行业与非资本品行业并进行回归，发现非资本品行业的溢出效应显著为正，而资本品行业的溢出效应显著为负。利用非资本品行业的估计结果及进口渗透率计算各行业的全要素生产率对14个贸易伙伴国的研发投入弹性。计算表明，对我国的技术溢出处于前5位的是美国、日本、德国、澳大利亚和加拿大，这一方面是因为这些国家的研发投入相对较大，另一方面是因为我国从这些国家的进口额也较大。

This paper estimates the contribution of both domestic R&D and technology spillover through import from 14 OECD countries to our Total Factor Productivity( TFP)growth applying industrial data and panel Dynamic Ordinary Least Square( DOLS ). The result shows that the contribution of domestic R&D ex-penditure is higher than that of import spillover both in coefficient and significance. Capital goods industries and non-capital goods industries are then regressed separately and the results show that there are positive spillovers in non-capital goods industries and negative spillovers in capital goods ones. This paper explains the result reasonably. Lastly,we calculate the elasticity of every non-capital industrial TFP to every trade partner's R&D capital stocks utilizing the result based on non-capital industrial regression.
