摘要
运用地理加权回归(geographical weighted regression,GWR)方法,对2003—2007年广东省21个地级市R&D知识溢出的空间非稳定性进行实证分析。通过传统的OLS知识对参数进行"平均"或"全局"估计,发现GWR是一种可以反映参数在不同空间具有非稳定性的研究方法。在对R&D知识生产进行参数估计时,局部模型GWR比全局模型OLS更好地模拟了数据;R&D知识生产的不同要素存在空间变异;由于各地的政策与经济基础各有不同,导致不同的区域知识溢出的效应各有特点。
An empirical study was conducted on Guangdong＇ s R＆D knowledge spillovers at city＇ s level by employing the technique of geographical weighted regression （ GWR）, a new technique for the analysis of spatial nonstationarity which simulate data better than the global model OLS. It found that there exists spatial heterogeneity spill situation between cities and that different policies and economic foundations in various areas result in their unique characteristics of knowledge spillover effect.
