摘要
笔者利用省域数据,分析了我国知识生产的空间分布差异与空间关联,并在回顾知识溢出测度方法的基础上,对Griliches-Jaffe的知识生产函数进行拓展改造,改变传统的单因素投入方式为双因素投入方式,同时将影响知识生产的其他因素如贸易进口、人力资本、FDI等纳入分析,构建以经济距离矩阵为空间权重矩阵的空间计量模型,结果表明经济水平邻近的区域间存在积极的知识溢出。
Using data of 31 provinces and districts in China, this paper analyzes the spatial distribution differences and spatial correlation of knowledge production, and based on the reviewing of the measure methods of knowledge spillovers, develops Griliches-Jaffe knowledge production function by changing the traditional single-factor input to the two-factor inputs, and then builds the spatial econometric model taking economic distance matrix as spatial weight matrix, mean while the other influencing factors such as import, human capital, FDI are also included in the analysis. The results show that there is a positive knowledge spillover between regions with similar economic level.
