中文摘要：

本文借鉴Hansen（1999）对非动态面板数据门槛效应的处理方法，以不同层次人力资本为门槛，分别研究了国外和国内邻近R＆D溢出对本地技术创新的影响。实证结果显示外资和国内地区间购买技术的R＆D溢出对本地技术创新的作用均存在不同人力资本门槛。在跨越门槛之后，高层次人力资本更适合吸收国外R＆D溢出技术。而同时我国大多数省份尚未跨越有效吸收国外R＆D溢出的高层次人力资本门槛，区域人力资本的配置以及人力资本结构的优化与升级问题急待解决。

英文摘要：

This paper, according to the threshold effect technique based on non- dynamic panel data provided by Hansen （ 1999）, studies R＆D spillover＇ s effect, from both the foreign and domestic trade, on technological innovation. Results show that wherever R＆D spillover is from, there exists evident threshold of human capital, which spilt the sample into two regimes. Beyond the threshold, high - level human capital is more effective in absorbing foreign R＆D spillover. It also shows that most provinces have not yet exceeded the threshold of high - level human capital in absorbing foreign R＆D spillover effectively. So it is of great significance to allocate regional human capital, and then promote its optimization and upgrading.
