本文分析了加强专利保护对增长的影响，其中商业秘密被引入作为一种额外的保护方法。加强专利保护减少了共同知识的数量，这对创新激励产生了两种不对称的影响。首先，由于竞争对手不能自由使用技术信息，这有助于成功的创新者获得更高的利润。其次，信息披露的减少降低了研发生产率。该模型表明，专利与商业秘密的相对重要性决定了前者的正效应是否超过后者的负效应。因此，在商业秘密泄露风险高的情况下，加强专利保护可以促进经济增长。相反，当风险较低时，更强的专利保护会阻碍增长。在福利分析中也发现了类似的相反结果。
This paper analyzes the effects on growth of strengthened patent protections, where trade secrets are introduced as an additional protection method. Strengthening patent protection decreases the amount of common knowledge, which has two asymmetric effects on incentives to innovate. First, as competitors cannot freely use technological information, it helps successful innovators earn higher profits. Second, less disclosure of information reduces R&D productivity. The model shows that the relative importance of patents versus trade secrets determines whether the former positive effect dominates the latter negative effect. As a result, strengthened patent protection can increase economic growth when the risk of leakage of trade secrets is high. Conversely, when the risk is low, stronger patent protection hinders growth. Similar opposing results are also found in welfare analysis.
