摘　　要：基于我国中低技术产业1996—2009年面板数据,结合GMM回归结果和技术差距理论,提出产业内进口中间品和产业外进口中间品的技术溢出均存在技术差距双门槛效应的假设,并用非线性动态面板门槛回归技术检验门槛效应的存在性和显著性.结果表明,产业外进口中间品不存在技术差距门槛效应,产业内进口中间品存在双门槛效应,且当中低技术产业全员劳动率低于2.61万元/年/人时,技术差距因素最有利于产业内进口中间品的技术溢出,暗示我国中低技术产业进口中间品的技术水平不高.Based on the panel data of Chinese low-and-medium technology industries in 1996- 2009, combinating the GMM regression results and the theory of technology gap, it hypothesizes that there is a double-threshold effect of tech- nology gap on technology spillover of both the intra-industry and the extra-industry import intermediates. Then it tests the threshold effect using threshold regression with non-linear dynamic panel data. The results show that there is no threshold effect of technology gap on the extra-industry import intermediates, but a double-threshold effect of technology gap on the intra-industry import intermediates. The coefficient is significantly positive when overall labour productivity of Chinese low-and-medium technology industries is smaller than 26.1 thousand yuan per year for one person, which means that the technology level of the intra-industry import intermediates is not very high.
