吸收能力、FDI溢出与科技进步——以山东省17地市为例的门槛效应研究

Absorptive Capability,FDI Spillover and Technological Progress——Research on Threshold Effect in 17 Cities in Shangdong Province

运用山东省17地市2000—2008年面板数据,从吸收能力角度入手,构建门槛模型实证分析外商直接投资(FD I)技术溢出对科技进步的促进作用。揭示研发投入强度、人力资本和基础设施等变量存在单门槛效应,技术差距存在双门槛效应,再用两阶段最小二乘(2SLS)回归说明了这些变量的门槛区间决定着FD I溢出促进各地区技术进步的效果差异。同时给出各市在吸收能力各方面的现状,最后提出政策建议。

A threshold model is constructed to analyze the non-linear relationship between the technology development of Shan Dong province and technology spillovers of FDI from the perspective of absorptive capability and based on the provincial panel data of 17cities in Shandong during 2000 - 2008. The empirical results show that R＆D density, human capital and infrastructure have unit threshold effect and technology gap has two thresholds effect. Then the estimated results of 2SLS regression model indicate the sufficient absorptive capability is the premise for FDI technology spillovers. Moreover,this paper uses graphs todemonstrate the current status of absorptive capacity in these cities and puts forward policy recommendations at last.
