# Overview of Wind Power Industry Value Chain Using Diamond Model: A Case Study from China
## 4 Discussion  
### Comparison Discussion  
Focused on the worldwide wind power development situation, countries such as China, United States, and India, have achieved outstanding performance; Japan is a notable exception. Even though Japan has limited wind resources compared to other Asian countries, its installed capacity ranked 4 th in the world in 2016 (~3 GW) [80]. To further discuss the value chain of the Chinese wind power industry, a comparison with Japan using a modified diamond model is presented in this section. 1. Factor condition. Wind power in Japan is restricted by two natural factors. For onshore, geographical distribution of wind resources is quite uneven across Japan, since wind energy resources are concentrated in the Hokkaido, Tohoku, and Kyushu EPCO regions, while the demand centers are located somewhere else [81]; this challenge remains the same with resource distribution in China. For offshore, Japan owns rich offshore wind resources, but more than 1600 GW potential wind energy is located in ocean with depths greater than 100 m. China is also enhancing offshore wind power development with support from the government and wind turbine companies. 2. Demand condition. Although wind power in China and Japan both confront the difficulty of grid-connection and transmission, Chinese generated wind power has increased from 5.5 TWh in 2006 to 286.1 TWh in 2017, but Japanese generated wind power increased only from 2.7 TWh in 2006 to 5.7 TWh in 2017, an extremely low rate. Moreover, one significant bottleneck of \begin{table}
