Measurement and improvement path analysis of China's manufacturing industry chain resilience

The resilience of the manufacturing industry chain is the key for the manufacturing industry to resist absorption risks and restore and update to maintain long-term stable development. This paper uses the entropy weight method to measure the industrial chain toughness of industrial enterprises above scale in 31 provinces, autonomous regions and municipalities directly under the Central Government from 2009 to 2021, and analyzes the measurement results of the industrial chain toughness in each province from the perspective of time, space and quality of industrial development. In order to narrow the development gap of China's regional manufacturing industry chain toughness, we should pay attention to the research conclusions of manufacturing product quality improvement, and provide stable guarantee for the long-term development of China's manufacturing industry.
