Journal of E-Technology Jie-Wei Name: Zhang 17 3 2026 https://doi.org/10.6025/jet/2026/17/3/122-138 https://www.dline.info/jet/fulltext/v17n3/jetv17n3_2.pdf This study investigates the impact of digital transformation on green innovation and examines whether managerial myopia constrains digital innovation activities. Grounded in Upper Echelons, Resource Based, and Dynamic Capability theories, the research addresses critical gaps regarding causal identification and the interplay between technological capabilities and managerial cognition. Utilizing a longitudinal dataset of Chinese listed manufacturing firms from 2011 to 2022, the analysis employs rigorous endogeneitycorrection techniques, including lagged variable estimation, Two-Stage Least Squares instrumental variable approaches, and Propensity Score Matching combined with Difference in Differences. The findings consistently demonstrate that digital transformation exerts a significant positive causal effect on green innovation, with results remaining robust across all identification strategies. Conversely, managerial myopia exhibits no statistically significant impact on digital innovation, suggesting that digital initiatives are largely insulated from short-term managerial orientations due to competitive pressures, institutional mandates, and relatively rapid operational payoffs. These results challenge conventional assumptions that managerial short-termism uniformly suppresses innovation, highlighting the strategic necessity of digital transformation in modern manufacturing instead. The study contributes to sustainability and corporate governance literature by providing robust empirical evidence on how digital capabilities drive environmental innovation while clarifying the limited role of managerial cognition. In practice, the findings underscore the importance of policy support for digital infrastructure and technology adoption as effective pathways to achieving longterm corporate sustainability and green technological advancement.
