We present an integrated model, SWITCH-China, of the Chinese power sector with which to analyze the economic and technological implications of a medium to long-term decarbonization scenario while accounting for very-short-term renewable variability. On the basis of the model and assumptions used, we find that the announced 2030 carbon peak can be achieved with a carbon price of ~$40/tCO2. Current trends in renewable energy price reductions alone are insufficient to replace coal; however, an 80% carbon emission reduction by 2050 is achievable in the Intergovernmental Panel on Climate Change Target Scenario with an optimal electricity mix in 2050 including nuclear (14%), wind (23%), solar (27%), hydro (6%), gas (1%), coal (3%), and carbon capture and sequestration coal energy (26%). The co-benefits of carbon-price strategy would offset 22% to 42% of the increased electricity costs if the true cost of coal and the social cost of carbon are incorporated. In such a scenario, aggressive attention to research and both technological and financial innovation mechanisms are crucial to enabling the transition at a reasonable cost, along with strong carbon policies.

China's traditional automobile industry lags behind that of the developed countries, but the development of New Energy Vehicles (NEVs) is an opportunity to catch up with the global automobile industry. In China, there has been a widespread attempt to "overtake on the curve" by developing cleaner technology for NEVs. To help with this transition, the Chinese government has introduced a large number of policies to promote the development of the NEV industry. In this study, we examined whether these policies have been effective by analyzing data about policies for China's NEV industry from 2006 to 2018, as well as the NEV patents filed in the United States, Japan, Germany, France, Korea, and China from 1988 to 2018. This paper uses quantitative analysis of policies and factor analysis. The results of the policy quantification regression analysis show that China's industrial policy has a significant influence on the number of patents. For example, China's aim to promote technological progress has been effective in developing an indigenous NEV industry, but whether China will succeed in "overtaking on the curve" is still unclear. The current state of development of NEV patents does not show China have a leading edge in NEV technology. China's NEV industry policies should be further strengthened, especially the core policies on technological innovation. • China's policy of encouraging new energy vehicles is effective. • China's "overtaking on the curve" strategy has not yet meet the expectations. • This study provides a reference for the policy making of the new energy automobile industry.
