China promotes the development of the wind power generation industry to reduce carbon dioxide and tackle air pollution. Under China’s wind generation subsidy policy, the wind power generation industry has developed rapidly and is also maturing. Feed-in tariff (FIT)is a significant subsidy policy for wind power. This policy entails the government offering a fixed electricity price to wind power enterprises, ensuring a share of renewable energy in the energy mix. An accurate assessment of the impact of subsidy policies on the development of the renewable industry is an essential basis for the scientific development of government subsidy policies. Here, we propose a study on the impact of China’s Feed-in tariff subsidy on the change in the installed capacity of wind energy. We employ a panel data regression to rigorously assess the magnitude of the impact of the Feed-in Tariff specified by the Chinese government on the development of the wind power industry. Finally, we derive the effect of the Feed-in Tariff on increased wind power installed capacity in Jiangsu, Shandong, and Guangdong, all in China’s Type IV zone. We expect our findings can contribute to the moderate control of government subsidies and the development of the renewable energy industry.
