通过放松行业间相互独立的假设,建立“空间”面板模型来估算中国工业全要素生产率,这不仅是对全要素生产率估算方法的理论上的一种改进,而且还是对空间计量方法应用的一次扩展。现有的空间计量方法大多用于刻画具体的地理空间的关系,而本研究不再将空间看成具体“空间”,而是看成一种抽象的“空间”,即行业间的投入产出关系。考虑行业间投入产出关系的“空间”面板模型不仅能够提高投入要素系数的显著性,而且还能纠正在未考虑行业相互关系情况下得出资本产出弹性的高估和劳动投入产出弹性负值情形。
In this paper, a "spatial" panel model is established to estimate the total factor productivity of Chinese industry by relaxing the hypothesis of mutual independence among industries. It is not only a theoretical improvement of the total factor productivity estima- tion method, but also an extension of the application of the spatial econometrics. Most of the existing spatial econometric methods are used to capture the relationship among the specific spaces. And this article no longer regards space as a specific "space", but as an ab- stract "space", that is, input-output relationships among the industries. The "spatial" panel model considering the interrelationship a- mong industries can not only improve the significance of the input factor coefficient, but also correct the over-estimation of the elasticity of capital output and the negative elasticity of labor output without considering the interrelationship of the industries.
