宁波FDI技术溢出效应的实证分析

FDI的技术溢出效应引起了理论界广泛关注，但现有研究认为FDI对不同地区的作用不一定相同。文章以宁波为例，根据柯布-道格拉斯生产函数建立衡量技术溢出效应的数学模型，利用宁波市相关数据，对其FDI技术溢出效应进行了实证分析。研究结果表明：宁波外商直接投资对本地经济产生了负面技术外溢效应，其原因在于宁波企业主要以劳动密集型为主，技术水平较低，与跨国公司差距大，自身技术吸收能力低。为此，文章从调整引资结构、促进内外资企业联动发展等方面提出了提升宁波FDI技术溢出效应的若干建议。

A Positive Study of the Technology Spillover Effect on Foreign Direct Investment in Ningbo

The technology spillover effect of FDI on those host areas has gained much attention. But researches have shown that FDI has different effects in different regions. This paper , combining with the data of using foreign capital in Ningbo, analyzed the ways of FDI technology spillover effect. According to the Cobb-Douglas production function, this paper established the mathematical model to measure the effect of technology spillover. The empirical study showed that the FDI in local economy had a negative technical spillovers effect. This paper gave the reasons from the way of FDI technology spillover. The enterprises in Ningbo are mainly labor-intensive with low levels of technology. Based on the analysis of the above influencing factors, this paper has brought some suggestions to promote the spillover effect of FDI in Ningbo.
