Replication Data for Does Democracy Cause Innovation?An Empirical Test of the Popper Hypothesis

Here is the data used in the paper titled "Does democracy cause innovation? An empirical study of the Popper Hypothesis". Democratic countries produce higher levels of innovation than autocratic ones, but does democratization itself lead to innovation growth either in the short or in the long run? The existing literature has extensively examined the relationship between democracy and growth, but seldom explored the effect of democracy on innovation, which might be an important channel through which democracy contributes to economic growth. This article aims to fill this gap and contributes to the long-standing debate on the relationship between democracy and innovation by offering empirical evidence based on a dataset covering 156 countries between the year 1964 and 2010. The results from difference-in-difference method show that democracy itself has no direct positive effect on innovation measured with patent counts, patent citations and patent originality.

本研究所用数据来源于题为《民主是否驱动创新？基于波普尔假说（Popper Hypothesis）的实证研究》的学术论文。民主国家的创新水平普遍高于专制国家，但民主化进程本身能否在短期或长期内推动创新增长？现有文献已针对民主与经济增长的关联展开了大量探讨，但极少关注民主对创新的影响——而这或许是民主促进经济增长的重要传导渠道。本文旨在填补这一研究空白，并基于涵盖1964年至2010年间156个国家的数据集提供实证证据，为民主与创新关系这一长期存在的学术争议提供经验支撑。双重差分法（difference-in-difference）的回归结果显示，以专利数量、专利引用量及专利原创性作为创新衡量指标时，民主制度本身对创新并无直接正向影响。
