However, its development in China is impeded by its high regulation price compared with coal power. Market reform is therefore of vital importance to promote the penetration of NGFE. The objective of this study is to analyze the impacts of market reform and the renewable electricity(RE) subsidy policy on the promotion of NGFE and RE. A dynamic game-theoretic model is developed to analyze the interaction among the NG supplier, the power sector and the power grid. Three scenarios are proposed with different policies, including a fixed regulation price of NG and electricity, real-time pricing(RTP) of NG and electricity, and subsidy targeted at RE. The results show that:(1) market reform can sharply decrease the NG price and consequently promote the development of NGFE and RE;(2) subsidy targeted at RE not only promotes the penetration of NGFE and RE, but also increases the utilization ratio of renewables significantly;(3) market reform and the subsidy also enhance consumers’ welfare by reducing their power consumption expenditure.展开更多

President Xi Jinping, during his term of office in Zhejiang, launched a number of seminars and activities to seek "a Zhejiang spirit that moves with the times." Forty years of reform and opening-up, the "Zhejiang spirit" has experienced an evolution that can be summarized as three improvements: from spontaneous formation to deliberate cultivation, from something limited to eastern Zhejiang to an integrating force that spans the entire Zhejiang Province, and from a mere existence to a role that functions adequately. The "Zhejiang spirit" is extracted from the humanistic spirits shaped in all corners of Zhejiang province. It is "an instrumental ensemble played across the entire province," and represents a certain judgment and interpretation. The "Zhejiang spirit" not only describes and summarizes the past and present, but will also guide and motivate the future, and support people in their enterprising and industrious practices to move with the times.展开更多
