Based on data from 50 manufacturing listed companies in Henan Province from 2019 to 2023, the DEA-BCC model and Malmquist index were employed to evaluate corporate operational performance from both static and dynamic perspectives. The findings reveal that the average comprehensive efficiency of the 50 manufacturing listed companies in Henan Province during from 2019 to 2023 is 0.834, primarily constrained by pure technical efficiency and scale efficiency. The total factor productivity of the sample companies is less than 1 and showes an overall declining trend, mainly due to a decrease in the technological change index. Based on these results, several recommendations are proposed for the future development of Henan's manufacturing sector, aiming to address regional development imbalances and enhance corporate operational performance.
