Biased technological progress and total factor productivity growth: From the perspective of China's renewable energy industry

With the decline in the intensity of subsidy policies, technological progress has become a critical factor in promoting the renewable energy industry's sustainable development. This paper estimates the direction and extent of biased technological progress in China's renewable energy industry from 2009 to 2018. On this basis, by constructing an accounting model for the growth rate of total factor productivity (TFP), this paper empirically analyzes the effects of different factors on TFP growth. The research results indicate that: (1) The TFP of China's renewable energy industry has dropped by 4.60% annually, and the growth of industrial output mainly relied on factor input rather than technological progress. (2) The technological progress and factor allocation of China's renewable energy industry generally show a bias towards the capital. At different stages of the industry's development, it presents different degrees of bias. (3) Technological progress is biased towards capital factor with a lower growth rate of factor efficiency, which hinders the growth of TFP in the renewable energy industry.

Automated summary

The study finds that the total factor productivity of China's renewable energy industry has been declining by 4.60% annually, with industrial output growth mainly relying on factor input rather than technological progress. There is a bias towards capital in terms of technological progress and factor allocation, leading to hindered growth of TFP in the industry.
