外商直接投资对工业行业内部的技术外溢

Technological Spillover of FDI Within Industry Sectors

本文利用1995-1997,2000-2003年期间,中国工业36个行业的平行数据,使用固定效应模型和随机效应模型估计了FDI对工业行业内部的技术外溢,及影响技术外溢的因素。结果显示:在1995-1997年期间,FDI对我国工业行业内部有不显著正的技术外溢。技术差距较小、劳动密集型行业获得较大的技术外溢。在2000-2003年期间,FDI对工业行业内部有显著正的技术外溢。技术差距较大、资本密集型工业行业获得较大的技术外溢。因此,本文的政策含义是,工业行业的引资应偏重技术差距较大的资本密集型行业。

Based on the panel data of a sample of 36 industry sectors during 1995-1997 and 2000-2003, this paper estimates the technological spillover effect of FDI（Foreign Direct Investment） to domestic industry finns with fix effect model and random effect model. The empirical study shows that： （1） in 1995-1997, technological spillovers are insignificantly positive; the technology gap and the sector characteristic of capital-intensive restrict the spillover effect of foreign direct investment; and （2） in 2000-2003, technological spillovers are significantly positive, the domestic finns in capital-intensive sectors and with bigger technology gap achieve higher spillover effect than those in labor-intensive and with less technology gap ones. This paper also analyzes the policy implications of the results.
