Abstract:

Negative intergenerational and environmental externalities are the basic characteristics of Chinese mining industries. Total factor productivity (TFP) had not taken dual negative externalities into account, while most studies on green total factor productivity (GTFP) only considered environmental pollution, and therefore it is difficult to measure the true efficiency of green technology in mining industries. In this study, dual negative externalities were added into the modified Solow residual model to measure the growth rate of GTFP based on the inter-provincial panel data of mining industries from 2005 to 2015, and then GTFPs were decomposed into the effects of technological progress, returns to scale, negative intergenerational externality, negative environmental externality, and so on. The results show that: (1) GTFP was generally lower than TFP without dual negative externalities, and the overall trend was more stable. (2) The GTFP of mining industries presented a clear increasing tendency. Ferrous metal mining industry had the fastest growth rate, followed by coal mining industry and nonferrous metal mining industry, and oil and gas mining industry had the lowest growth rate. (3) The decomposition of GTFP shows that negative intergenerational and environmental externalities both restrained GTFP. Through a comparative analysis, we found that coal and nonferrous metal industries were greatly affected by negative environmental externality, while extraction of oil and gas and ferrous metal mining were more affected by negative intergenerational externality.

Key words: mining industry, green total factor productivity, negative intergenerational externality, negative environmental externality
