China's carbon emission trading market has been formally established, but few studies have been conducted to analyze the impact of this policy on the regional urbanization level. Therefore, this paper evaluates whether the carbon trading pilot policy can enhance the regional urbanization level in China through the difference-in-differences method and analyzes the mediating role of industrial structure upgrading in this process. The results prove that the carbon trading market policy can accelerate the transformation and upgrading of industrial structure in the region so that it promotes the development of regional urbanization. Moreover, the effects of the policy are concentratedly manifested in the eastern region of China.

Green biased technological progress takes into account the influence of energy input and pollution emission, which is of great significance to China's green development. This paper decomposes technological progress into green input biased technological progress (IBTC) and green output biased technological progress (OBTC) using the Slacks-based measure integrating (SBM) model. Factor bias in technological progress is determined based on data from 34 industries in China from 2000 to 2015. The results show that the green biased technology progress exists significantly in the industry, and most of them promote the growth of green total factor productivity. IBTC first tends to consume energy to pursue capital between capital input and energy input, while it tends to save energy after the Eleventh Five-Year Plan. Between labor input and energy input, it is biased towards saving labor and consume resources. OBTC is biased towards promoting industrial growth and curbing pollution emissions. Medium and light polluting industries are biased towards promoting industrial growth and curbing pollution emissions, while heavy polluting industries are biased towards emitting more pollution.
