Implementing intelligent manufacturing policies to increase the total factor productivity in manufacturing: Transmission mechanisms through construction of industrial chains

In recent years, the Chinese government has focused on implementing intelligent manufacturing policies to improve the total factor productivity of the manufacturing industry. Using a sample of listed manufacturing companies from 2010 to 2022, we examined the long-term economic effects of government intelligent manufacturing policy incentives on the total factor productivity of the manufacturing industry. We systematically explored its transmission mechanism in the construction of industrial chains. The study found that the implementation of intelligent manufacturing policies significantly improved the level of total factor productivity in the manufacturing industry. Mechanism analysis found that intelligent manufacturing policies promoted the construction of the manufacturing industry chain through three paths: optimizing industrial chain integration, enhancing industrial chain spillover, and strengthening industrial chain resilience, thereby promoting the improvement of total factor productivity. Further analysis found significant differences in the implementation effects of different policy types and technology requirements.
