FAQS about Photovoltaic power generation policy

Are photovoltaic power generation policies effective?

Existing qualitative research on photovoltaic power generation policies has preferred sorting, summarizing, and performing comparative analyses of policies, focusing on their effectiveness and efficiency. Meanwhile, policy synergies have been ignored when studying the effectiveness of photovoltaic power generation policies.

Are China's policies on photovoltaic power generation consistent?

The results show that changes in the degree of synergy between policy goals and measures tend to be consistent and that China's policies on photovoltaic power generation have gradually shifted to the combined use of different policy measures.

What are the policy goals of photovoltaic power generation?

The policy goals of photovoltaic power generation are divided into three aspects: improving technology and promoting production, promoting construction and application, and guaranteeing and maintaining application effects.

Who formulates policies on photovoltaic power generation?

Nevertheless, policies on photovoltaic power generation have been mainly formulated by a single department: the National Development and Reform Commission or the National Energy Administration. In addition, as shown in Fig. 1, before 2009, there were no multiple departments formulating or issuing policies without synergy between departments.

What is the policy strength of the photovoltaic industry?

The policy strength of the photovoltaic industry includes national-level policy strength and regional policy strength. The regional policy strength will be given the weight on the proportion of the regional PV installed capacity in the China’s PV installed capacity. The regression results are shown in Table 3, Table 4, Table 5 and Table 6. Table 3.

Are photovoltaic power generation policy Synergy based on text mining?
