我国区域技术创新能力空间相关性及扩散效应实证分析——基于1997-2008空间面板数据

The empirical analysis about spatial correlation and diffusion impact in regional technological innovation—Based on 1997-2008's spatial panel data

本文在知识生产函数的基础上,将三种知识扩散渠道纳入分析范围,结合传统影响区域技术创新能力的因素进行综合考虑.同时结合空间计量经济学分析工具,以全国总体样本,分地区子样本和两两地区分类比较子样本为分析对象,对技术创新能力和相关影响因素在区域内部及区域间的扩散效应进行了实证研究.不同样本的分析结果表明:全样本和分地区样本两个视角分析均证实了我国整体各省份间以及地区和地区间的技术创新能力具有显著的空间相关性,但是地区内部和地区间的空间相关性形式有所区别.具体的变量估计结果显示:三种空间知识扩散渠道变量中,一地区周边地区的FDI和进出口贸易无论是区域间还是在区域内部的分析层面上均没有对本地的技术创新能力产生显著影响;在影响区域创新能力的传统变量中,全国总体以及大部分地区内部的技术市场活跃度,科技人员保有量和进出口贸易对区域整体技术创新能力有显著影响.

Based on the knowledge production function, this paper brought three knowledge diffusion channels and traditional elements that influenced the regional technological innovation into analysis pro- cess. After that, it used the spatial econometrics to do empirical analysis on the relevant elements and diffusional effects towards entire country, solo region and two-two regions seperately. The different results illustrated that there exists remarkable spatial relationship towards entire country＇s and regional techno- logical innovation. Additionally, different samples showed different spatial relational form. The specific variables estimation result showed that the three spatial knowledge diffusion channel variables didn＇t play remarkable influence to the local technological innovation. In the traditional variables that influenced the local technological innovation, the dynamics of knowledge market, knowledge labor and im-export trade played remarkable influence.
