摘　　要：采用2003—2012年中国除西藏外30个省市自治区的面板数据,考察信息通信技术渠道国际R&D溢出效应。运用面板单位根检验、协整检验、相关性分析、格兰杰因果检验、随机效应模型等计量方法,研究中国通过信息通信技术渠道获得的国际R&D溢出与当地全要素生产率之间的关系;建立Hansen非动态面板门槛模型,采用稳健标准差回归,检验各省份由信息通信技术渠道获得的国际R&D溢出门槛效应,并从产业转型升级和信息化建设角度分析存在门槛效应的原因。结果表明,中国大部分省份通过信息通信技术渠道获取的国际R&D溢出与全要素生产率有正相关关系;通过信息通信技术渠道获得的国际R&D溢出对当地技术进步的影响存在明显的地区差异和门槛效应。This paper examined the international R＆D spillover effects via information and communication technology by using the panel data of China＇s 30 provinces except Tibet from 2003 to 2012. It investigated the relationship of international R＆D spillover via information and communication technology and the local total factor productivity by using panel unit root test, co-integration test, correlation analysis, granger causality test and random effects model. Then it tested the threshold effect of international R＆D spillover via information and communication technology channel by establishing Hansen non-dynamic panel threshold model and using robust standard errors regression. It analyzed the reasons from the perspective of industry transformation, upgrading and information construction. The results show a positive correlation between international technology spillover via information and communication and total factor productivity in most provinces of China, while international R＆D spillover via information and communication technology has obvious regional difference and threshold effect.
