Abstract: To change the way of industrial development is to reduce consumption, improve resource use efficiency, and improve input-output ratio. However, due to the impact of such factors as the economic structure, the price control and the energy “rebound effect” etc., the variation trend of industrial input-output rate may be inconsistent with that of energy efficiency. On the basis of the measurement of total factor productivity of industrial energy at the Pearl River Delta during the period of 2000 to 2014 with the method of super-efficiency DEA, this paper adopts the static panel and dynamic panel to carry out an empirical test. The results show that the input-output ratio has negative effects on the total factor productivity. It is necessary to change the mode of industrial development from investment-driven to innovation-driven, guide the innovation and diffusion of energy-saving technology, and encourage foreign capital to transfer and diffuse more intermediate products containing advanced technologies and core technologies.

Key words: industrial input-output ratio; energy total factor productivity; industrial development mode
