Abstract:The evolutionary analysis of PV policy is a key means for us to grasp the development of past policies, a reference for future policy formulation, and an important basis for policy evaluation and optimization. Based on the social network analysis and co-occurrence analysis methods, this paper displays the changes of policy hotspots in a visual form and describes the dynamic evolution process of China's PV policies. At the same time, according to the changes in PV policy hotspots, key events and policies, the evolution process is divided into five phases to discuss: Market environment cultivation stage (~2008), Domestic application market development stage (2009~2012), Distributed PV promotion stage (2013~2014), Marketization and intelligence stage (2015~2017), Policy retreat stage (2018~). It can be found that the evolution of China's PV policy reflects the development characteristics of high quality, diversification, intelligence, and marketization. This is further discussed in terms of policy objectives, policy instruments, and the drivers of policy evolution.
