With the continuous deepening of the energy transition strategy and the coming new energy grid-parity
both the development characteristics of new energy and the external situation have changed. Thus
there is an urgent need to analyze the basic principles and key issues of high-quality development of new energy in energy transition. This paper summarized the state and trend of new energy development in China
and analyzed the challenges of new energy development in energy transition and measures to promote high proportion of new energy in foreign countries. On this basis
it further clarified the basic principles which high-quality development of new energy should follow
and analyzed several key issues of high-quality development of new energy
and then proposed the evaluation indexes for high-quality development of new energy.
