摘　　要：在要素投入与TFP相关的前提下,以工业面板数据为样本,分离具有非观测性和特异性的TFP,用Levinsohn-Petrin非参数理论对索洛余值进行修正估计,结果表明TFP年均有所增长,但在产出增长中所占份额较低;工业存在规模报酬递增。基于技术外溢的检验显示:后向外溢和行业竞争没有提升TFP,前向外溢和规模效应提升TFP,上游行业从下游行业外资企业所得规模效应经由前向关联渠道反哺了下游行业TFP。Relaxing the hypothesis of un-correlation between inputs and TFP, this paper subtracts the unobservable and idiosyncratic TFP from regression residual, and using panel data of 36 indus- tries from 2001-2006, to estimate the production equation with Levinsohn-Petrin＇ s non-parametric theory. The results show the growth of TFP improves, but share of its contribution to output growth is low. And it also shows there is increasing return to scale in industry. From view of technology spillover, the paper finds that effects of backward technology spillover and competition doesn＇ t im- prove TFP, but effects of forward technology spillover and increasing return to scale do. And via for- ward linkages, the effect of increasing return to scale acquired by up-river industry from down-river FDI, is fed back to improve TFP of down-river industry.
