A comprehensive examination on the structure and resilience of the industrial system, and their changes in the context of major events, contributes to a deep understanding about the relationships of production cooperation among industries and maintains the stability of the system; moreover, this is helpful for scientifically allocating production resources and promoting the transformation and upgrading of industries. This paper takes input-output tables as the data foundation, and combines complex network theory with integer programming method to construct an "input-output-integer programming" complex industrial linkage network; furthermore, it explores the variations in the structure and resilience of China's industrial system. The empirical results show that: ⅰ) The structure of the industrial system significantly impacts the GDP growth rate, and the denser the former is, the faster the latter is, and vice versa. Over the past decade since 2011, the structure has become increasingly loose; ⅱ) major events, such as stimulative economic policies implementation and supply-side structural reform, shorten the distance for resource transfer between industries and improve the structure of the industrial system, but their impacts on the system are localized; however, the events like european debt crisis escalation, China-US trade friction intensification, and COVID-19 outbreak extend the distances, resulting in negative shocks and widespread impacts; ⅲ) compared to in periods of high-speed economic growth, the structure of the industrial system loosens in times of medium to low growth, leading certain industries to play an "intermediary" role cross a large range to coordinate resource allocations and satisfy production demands. This phenomenon is particularly evident during China-US trade frictions and COVID-19; ⅳ) from 2011 to 2020, the resilience of the industrial system consistently remains at a high level but exhibits a weakening trend. Driven by relevant economic policies and market reforms, the system significantly improves its defense, adaptation, and recovery capabilities in the face of impacts from major events.
