We suggest that when the manager is myopic due to pressure from financial analysts and decides to reduce innovation, the firm should retain better innovation projects and forego worse projects. Accordingly, the average value of innovations improves. Empirically, we find that analyst coverage is positively correlated with patent value. We perform a difference-in-differences analysis and confirm our previous findings. Further, the positive effect of analyst coverage on patent value is lower for firms with more long-term projects and for firms with fewer patents per technology class.分析師報導如何影響企業創新未有定論。本文提出，當管理者因分析師壓力造成短視近利而減少創新時，會選擇保留好計畫並放棄較差項目，提高整體創新價值。實證發現分析師報導與專利價值為正相關。使用差異中之差異分析，結果仍成立。而當公司有較多長期計畫或每項技術類別專利數較少時，會減弱分析師報導對專利價值的正效果。enAnalyst coveragepatent valueinnovation分析師報導專利價值創新journal article10.6545/JFS.202309_31(3).0001
