Total Factor Productivity Analysis of Industrial Processes Based on Malmquist Model

The production of industrial process is the key factor of evaluating the national industry production level. Therefore, this paper proposes total factor productivity analysis method based on Malmquist model to analyze the production efficiency statically and dynamically. Based on the input and output data of ethylene production plants in China, the total factor production index of ethylene production plants in industrial processes is decomposed into technical efficiency, technical progress, pure technical efficiency and scale efficiency through the Malmquist model based on the data envelopment analysis (DEA). Moreover, the energy efficiency of ethylene production plants can be improved.
