报告内容摘要：
This study explores the impact of automation innovation on labor income share. We develop a model integrating task-based production with endogenous wage bargaining and innovation decisions, and show that automation innovation reduces labor income share by weakening workers' bargaining power and displacing labor-intensive tasks. The strength of these mechanisms varies with workforce adaptability and automation risk level. We test these theoretical predictions using a novel firm-level panel dataset of 10,235 firms across 65 countries from 1996 to 2015. Consistent with the model, we find that automation innovation significantly reduces the labor income share through both predicted channels. These results are robust to various specifications and endogeneity controls. Heterogeneity analysis reveals that the negative effect of automation innovation on labor share is concentrated among large and very large firms, in capitalintensive and manufacturing sectors, in countries with weaker labor regulations, and in developing economies.
