漏损、FDI外溢效应弹性和东道国福利

FDI对东道国福利负的外溢效应源于其漏损的存在,然而目前的文献少有对漏损的分析。本文的两部门模型在Ramsey的框架下考虑FDI带来的漏损,说明外资企业技术水平对内资企业技术水平的影响弹性影响均衡消费增长率。忽略其他因素,促进外溢效应弹性大于1有利于东道国福利的提升。运用1999年到2004年省区面板数据的实证分析说明,总体而言FDI外溢效应缺乏弹性,因此理顺外溢效应发挥的渠道成为当务之急。

Leakage,FDI Spillover and Host Country's Welfare

Leakage leads to negative spillover to host country's welfare.In this paper,we consider leakage in a two-sector model based on Ramsey.We explain that the elasticity of spillover of FDI affects equilibrium consumption growth rate.Ignoring other factors,it is of beneficial to social welfare when promoting the spillover elasticity bigger than 1.The provincial panel data from 1999 to 2004 of China proves that FDI spillover elasticity is smaller than 1 as a whole.It is urgent to widen the channels of spillover.
