摘要：This study examines the effect of harmonized patent disclosure on the efficiency of firms’ research and development (R&D) investment. It takes advantage of a unique setting: the Global Dossier portal, which harmonizes patent disclosure across multiple countries. I use the introduction of this portal as a natural experiment and I find consistent evidence that patent disclosure harmonization reduces uncertainty about patent validity and the cost of processing patent information, resulting in better R&D investment decisions. My results also show that firms reporting in non-English languages benefit more from harmonization than those reporting in English due to reduced processing costs. Further analysis reveals that Global Dossier leads to the increased use of foreign patent information and a geographically diverse set of patent applications, which validates the enhanced use of patent information. The study offers novel insight into the impact of global disclosure harmonization on firm operations.

本研究探讨了协调一致的专利披露对公司研发投资效率的影响。该研究利用了一个独特的事件：全球专利档案门户的推出，该门户协调了多个国家的专利披露。我使用这个门户的引建立作为一个自然实验，并且我发现有一致的证据表明，专利披露的协调减少了关于专利有效性的不确定性和处理专利信息的成本，从而导致了企业更好的研发投资决策。我的结果还显示，报告非英语语言的公司因为处理成本降低而比报告英语的公司更受益于信息披露协调。进一步的分析揭示，全球档案导致了外国专利信息的增加使用和地理上多样化的专利申请集合，验证了专利信息使用的增强。该研究为全球披露协调对公司运营的影响提供了新的见解。
