在本文中，我提供了新的估计的相对影响，国内和国际知识溢出的创新和生产率在企业层面上，使用以前未开发的面板数据从美国和日本。我的估计表明，知识溢出主要是在国家内部的范围内，提供了一个重要的假设，在许多理论文献的实证证实。结论中讨论了这一发现的影响。
In this paper, I provide new estimates of the relative impact of intranational and international knowledge spillovers on innovation and productivity at the firm level, using previously unexploited panel data from the U.S. and Japan. My estimates suggest that knowledge spillovers are primarily intranational in scope, providing empirical confirmation of an important assumption in much of the theoretical literature. The implications of this finding are discussed in the conclusion.
