Corporate governance and firms' efficiency in China's manufacturing listed companies from dynamic perspectives.

This research applies the dynamic slack-based measure (DSBM) model to evaluate the dynamic efficiency of manufacturing companies in the long run and uses the Censored Least Absolute Deviations (CLAD) model to analyze the effect of corporate governance on their overall efficiency and the efficiency of each input factor. We find the following main results. First, overall efficiency of the manufacturing industry listed companies is low. 2) Debt efficiency is lower than the efficiency of shareholders' equity and exhibits a downward trend. 3) Labor efficiency is the lowest among all inputs. 4) The efficiency of the medicine and bio-products industry is the highest, while the efficiency of the paper and printing industry (which causes serious pollution) is the lowest. 5) Companies with low export intensity and high capital intensity are the most efficient, while companies with high export intensity and low capital intensity are the least efficient. 6) Ownership concentration and efficiency have a significantly positive U-shape relationship. 7) Board size and efficiency have a significantly inverted U-shape relationship. 8) An actual controller with a state-owned nature has a significantly negative impact on efficiency. 9) Executive compensation, equity incentive, and institutional ownership have a significantly positive impact on efficiency.
