Abstract: This research explores the role of technological innovation incentive policies in enhancing labor income share amidst the backdrop of a new technological and industrial revolution, aiming to foster high-quality and equitable economic development. Utilizing a double-difference model and a quasi-natural experiment framework, it examines the effects of high-tech enterprise recognition policies on labor income within firms. The findings indicate that such policies significantly increase the labor income share, and this positive effect is more pronounced in the eastern region, in enterprises with higher capital intensity and reliance on external financing, and in enterprises with better quality of internal control. The mechanism analysis suggests that these incentives promote human capital development by advancing technology and alleviating financial constraints, thereby increasing labor income shares. Additionally, the policy's impact is moderated by regional marketization levels and firms' political affiliations. Strikingly, the policy benefits ordinary workers more than executives, aligning with the principles of equitable wealth distribution. The study underscores the importance of maintaining and refining technological innovation incentives to improve income distribution patterns in the modern economy.
