外商直接投资隐性知识空间溢出——基于修正的Lichtenberg-Pottelsberghe模型估计

Spatial Spillovers of Tacit Knowledge from FDI——Estimation Based on the Modified Lichtenberg-Pottelsberghe Model

考虑到FDI隐性知识在东道国内陆区域间的二次溢出效应,本文将线性框架下的国际研发知识溢出模型扩展成为非线性结构的空间Durbin模型.基于中国1992—2011年31省面板数据的检验结果显示:FDI资本投资及其货物进口所带来的知识物化型资本品无助于当地全要素生产率的进步;但FDI资本投资所带来的非物化型隐性知识却在中国省域间产生了显著的空间溢出效应,提升了毗邻地区全要素生产率及技术进步率.建议引资政策应重视FDI隐性知识在中国内陆区域间的扩散,而非FDI实体资本品投资.

Considering spatial dependency of tacit knowledge from FDI which can motivate knowledge spillover among regions, it developed the model of international R＆D knowledge spillover from linear structure into nonlinear structure named spatial Durbin model. By using the panel data including 31 Chinese provinces from 1992 to 2011, it finds that the explicit knowledge embedded in capital goods via foreign investing and importing hasn＇t improved local total factor productivity, but the un-embedded tacit knowledge from FDI has promoted other regions＇ total factor productivity except location of FDI. It suggests that the policies of absorbing foreign investment should pay more attention to tacit knowledge spillover effects rather than capital goods brought by FDI.
