摘要

China's transportation development has entered a new era, and TFP estimation needs to be combined with the new development concept. This paper uses China's provincial panel data and Malmquist-luenberger (ML) index method to measure the green total factor productivity of the transportation industry in China, and it also analyzes the whole change trend and regional characteristics about the total factor productivity of the transportation industry combining the Zofio decomposition method. The results show that: The traditional method of Malmquist index that ignores the unexpected output will underestimate total factor productivity and technical change, and will overestimate the technical efficiency. The green total factor productivity of the transportation industry in China shows a downward trend under the condition of reducing energy and emission because of the decline of pure technical efficiency before 2007 and the decline of pure technical efficiency change after 2008.
