Abstract: Under the wave of intelligence, intelligent manufacturing is the core driving force to promote the deep reform and high-quality growth of China’s manufacturing industry. This paper regards the intelligent manufacturing policy as a quasi natural experiment, and constructs the traditional double difference model. It is found that the implementation of the intelligent manufacturing policy helps promote the development of new quality productivity of enterprises, which has a significant positive impact on the substantive and permeable elements of the new quality productivity. The mechanism analysis shows that the intelligent manufacturing policy can reduce the pressure of enterprise capital constraints, improve the efficiency of enterprise resource allocation and the level of digital innovation, and help the development of new quality productivity of enterprises. Heterogeneity analysis shows that for enterprises in areas with better digital infrastructure, enterprises with higher management shareholding ratio, enterprises in areas with higher degree of intellectual property protection and labor-intensive enterprises, the role of intelligent manufacturing policy in promoting the development of new quality productivity of enterprises is stronger. In addition, the easing of enterprise capital constraints, the efficiency of resource allocation and the improvement of digital innovation ability all play a greater role in promoting the productivity permeability factors. The research conclusion has certain enlightenment for enterprises to implement intelligent manufacturing and develop new quality productivity.
