中文摘要：

国际智力流动是各国政府高度关注的问题.文章立足于中国的实际情况,讨论并验证了海外智力资本回国后,存在一个以省域为考察对象的流向性问题,且这种空间流动与通常预期的阶梯状动态存在较大差异.通过引进空间计量经济学的研究方法,分析了海外智力回流后的空间聚集效应,在考虑了空间依赖性与规模经济的前提下,研究发现：各地区政府的研发投入、经济主体对于科研活动的生产性投入,以及海外回流智力资本的知识溢出,三者的增长率与该地区知识研发的产出效果成正向相关关系,来自政府投资的效果最明显,经济主体的研发投入次之,智力资本空间溢出则效果较弱.为此,提出应鼓励海归人才均衡流动,采取多种措施,扩大对海归人员的吸引力等政策建议.

Through the introduction of spatial econometric methods,it analyses the space aggregation effect of overseas in-telligence return.This article finds that it should get more reasonable explanation of China’s regional science and technology innovation activities,under the premise of considering the spatial dependence and scale econo-my.Finally,the paper makes policy recommendations on the technological spatial balanced development of in-telligence returning.
