摘　　要： 利用2000～2009年中国大陆31个省域的面板数据,本文采用空间计量方法的空间误差模型和地理加权回归模型,测度了北京、上海两地的技术扩散对全国各区域经济增长的影响。研究表明:对于多数区域而言,来自北京、上海的技术扩散对区域经济增长存在促进作用,并且整体上看,来自北京技术扩散的总体影响要高于上海,但两个城市的影响均低于本地R&D、国外的技术扩散。同时,北京、上海的技术扩散效果随地理距离而发生变化。实证结果肯定了京沪作为国家中心城市对全国区域经济增长的引领作用。但京沪技术扩散弹性值总体较低,并且更多是对邻近区域的扩散,也表明京沪对外技术扩散辐射半径有限。 The technology diffusion effect of Beijing and Shanghai on reginal economic growth is compared through SEM and GWR model of spatial economic analysis with 31 provincial panel data from the year of 2000 to 2009. The result shows that for the most of provinces in China, the more technology diffusion from Beijing and Shanghai is, the more it promotes local economic growth. And as a whole, local economic growth effected by Beijing is higher than that by Shanghai. However, comparing with the technology diffusion of Beijing and Shanghai, local R＆D and foreign technology diffusion have higher effect on local economics. In addition, the effect on local economic by the technology diffusion of Beijing and Shanghai changes with the geographical distance. This result confirms that as na- tional heart cities, Beijing and Shanghai really play a guiding role in natioual economic growth. However, the elasticity values of tech- nology diffusion for Beijing and Shanghai are still at a low level. And both technology diffusion radiation radius of Beijing and Shanghai are small, which means that provinces located around the two heart cities receive the most of their technology diffusions.
