論文概要:Due to human concern for energy security and environmental deterioration, there is a global consensus on making full utilization of renewable energy (RES). Photovoltaic (PV) presents the significant cost reduction among all renewable energy sources and has experienced rapid growth. After decades of development, Germany and Japan have become the leading PV countries in terms of market size and cumulative installed capacity. Meanwhile, China's photovoltaic industry has developed rapidly in recent years and has become the world's largest PV market.

This paper focuses on research about the development and diffusion of Photovoltaic solar energy in Germany, Japan, and China. Compare the strengths and weaknesses of those three countries and draw lessons from the Germany case and Japan case. To compare the PV development in three different countries from the perspective of Technological Innovation Systems (TIS) framework, which focuses on a particular technology and includes all those factors that influence the development and diffusion of a technology. This framework proposes seven System Functions: key processes that need to be fulfilled for TIS to function well include international factors in the framework such as technology diffusion and market influence between countries. By mapping and measuring the key processes within TIS. Analysis process identifies the drivers and barriers that trigger or hamper in the development, diffusion or implementation of innovations. The main founding from the Germany and Japan cases is that successful TIS needs time to build up, and TIS are supported by stable institutional conditions to obtain knowledge from experimenting with the technology, form strong networks that have an impact on learning processes and policy making and build up and maintain legitimacy and support from investments. Finally, based on practical experience from Germany and Japan, presents the political suggestion and market advice for PV industry development in China.
