出口贸易技术外溢效应的地区差异与吸收能力的门限特征——基于非线性面板数据模型的实证分析

Regional Difference of Export Technology Spillovers and Threshold Characters of Absorptive Capabilities

本文首先利用Feder两部门外溢模型及中国30个省、自治区、直辖市的面板数据,对出口贸易在不同地区的技术外溢效应进行了检验。检验结果验证了出口贸易的技术外溢效应在我国不同地区之间具有显著差异。在此基础上,本文采用"门限回归"方法构造非线性面板数据模型,进一步检验了各类技术吸收能力对出口贸易技术外溢效应的影响,并从各个地区的基础设施、经济发展状况等方面测算了引发积极出口贸易技术外溢效应的门限水平。

Based on Feder （1982） , this paper investigates the technology spillover effects of export in different provinces of China. Using China＇s panel data of 30 provinces during 1991- 2007, it reveals that export affects the local economic development differently in different provinces, and the threshold effects of economic development exist. By using threshold regression model, it further empirically measures the threshold levels which ensure the spillover effects in several aspects, including the level of local economic development, the openness of region, the infrastructure establishment, and the industrial structure.
