American Inventors, 1870-1940

This repository includes data and code for our project "Changes in the Demographics of American Inventors, 1870-1940," The data contain information on individuals who received a US patent between 1870 and 1940 matched to the Population Census. The Code folder includes all of the code we wrote to create the datasets and then run the analyses. The replication_readme.md should explain how the code works. We have chosen to only include in the Data folder our set of matched patentees and not all of the data used in the paper. If you have questions, please contact Nicolas L. Ziebarth ([e-mail])本仓库收录了我们题为《1870-1940年美国发明家人口结构变迁》的项目所使用的数据与代码。本数据集涵盖1870至1940年间获得美国专利的个体信息，且上述个体信息已与美国人口普查数据完成匹配。代码文件夹包含我们为构建该数据集并开展相关分析所编写的全部代码，replication_readme.md文件将详细说明代码的运行流程。我们仅将匹配后的专利持有人数据集收录至Data文件夹，并未包含论文中使用的全部原始数据。如有疑问，请联系Nicolas L.
