摘要
R&D活动对地区经济增长产生着举足轻重的作用,在产业间和区域间存在着溢出效应。笔者分析了R&D在产业和区域间的技术扩散强度,同时计算了技术乘数。研究结果显示,技术乘数较小的部门生产技术,而技术乘数较大的部门使用技术,R&D溢出主要从技术生产部门流向技术使用部门;各区域的产业技术结构具有一定的相似性。
The R＆D activities play an important role on the regional economic growth with spillover effects among industries and regions. Based on the interregional input -output table of China in the year 2000, this paper researches the technological diffusion of R＆D among industries and regions by computing the industry＇s technology muhiplier. The results show that the industries with a low multiplier generate knowledge, whereas industries with a higher multiplier use knowledge. R＆D mainly flows from technology producing industries to technology using industries. The industries＇technological structure shares the similarities.
