Analysis On Efficiency And Total Factor Productivity Of China's Industry(1981-2015)

China's industry is now facing several conflicts such as industrial restructuring and upgrading,pressure of resources and environment.This paper analyses China's 35 industries from 1981-2015,applying MAM model and Luenberger–Hicks–Moorsteen productivity indicator to measure and decompose efficiency and productivity growth.What's more,we combine environmental regulation and R&D to do empirical research on influencing factor of efficiency and productivity growth of China's industries.We have drawn the following conclusions: China's comprehensive inefficiency has a growing tendency while heavy industry performs worse than light industry.The main reasons of inefficiency are too much pollutant and energy input.However,output inefficiency of light industry is mainly caused by insufficient of value-added,which may be related to difference of industrial structure.Natural emission is still the main way of discharging,but the ratio of managerial emission is rising to some extent.Taking into account of total factor productivity of industry,the accumulative total factor productivity of heavy industry is higher than light one.However,in different period,heavy industry does not always perform better.Technical change mainly contributes to productivity growth.Environmental regulation has leading role on R&D but it is bad for efficiency growing.Meanwhile,It has some positive impact on total factor productivity,output indicator,technical efficiency and scale efficiency.Based on the above conclusions,we suggest on laying emphasis on upgrading industries,developing technical change,implementing proper environmental regulation to improve efficiency and total factor productivity of China's industry.
