摘要
针对技术进步偏向的空间扩散现象,本文在理论分析基础上,通过构建面板平滑迁移(PSTR)模型对技术进步偏向空间扩散的非线性特征进行了实证检验。结果表明:在经济体要素禀赋结构既定的条件下,技术进步偏向会随技术的空间扩散而产生扩散现象;由于引进地区会对引进技术进行消化、吸收,这导致原有技术的要素偏向特性在空间扩散过程中发生改变,故技术进步偏向的空间扩散呈现出显著的非线性特征;当技术创新模式为适宜性创新模式时,引进地区对引进技术的消化、吸收能力较强,引进技术原有的偏向特性会发生较大改变,这时技术进步偏向的空间扩散效应较小,反之较大,因而技术进步偏向的空间扩散效应存在创新模式的门限效应。
Factor-biased technical process tends to diffuse in space.Firstly,this paper makes a systematic theoretical analysis of this phenomenon.Then,the panel smoothing migration model(PSTR)is constructed to test the non-linear characteristics of spatial diffusion of factor-biased technical progress.The results show that under the condition of fixed factor endowment structure,factor-biased technical progress tends to diffuse with the spatial diffusion of technology.Because the imported areas will digest and absorb the imported technology,which leads to the change of the original bias of imported technology in the process of diffusion,the spatial diffusion of factor-biased technical progress presents significant non-linear characteristics.Moreover,when the technological innovation mode is suitable,the imported regions have strong abilities to digest and absorb the imported technology,so the original bias of imported technology will change greatly,and the spatial diffusion effect of factor-biased technical progress is smaller.Conversely,the effect is greater.Therefore,the spatial diffusion effect of factor-biased technical progress has the threshold effect of innovation mode.
