我们分析了1980-2000年期间六个大型工业化国家的国家和国际，部门内和部门间R&D溢出对创新活动的相对影响。我们使用欧洲专利局的专利申请来衡量创新及其引用，以追踪135个狭义技术领域内和之间的知识流动。利用面板协整分析，我们发现部门间溢出对创新活动有关键影响，国内研发比国际研发具有更强的影响。然而，在技术领域内，估计国际R&D溢出是国家R&D效果的2.4倍。我们发现化学、电子和机械行业之间存在显著差异。
We analyze the relative effects of national and international, intrasectoral and intersectoral R&D spillovers on innovative activity in six large, industrialized countries over the period 1980–2000. We use patent applications at the European Patent Office to measure innovation and their citations to trace knowledge flows within and across 135 narrowly defined technological fields. Using panel cointegration we show that intersectoral spillovers have a key impact on innovation activities and that domestic R&D has a stronger effect than international R&D. However, within technological fields, estimated international R&D spillovers are 2.4 times the national R&D effects. We find significant differences across chemicals, electronics and machinery industries.
