# Overview of Wind Power Industry Value Chain Using Diamond Model: A Case Study from China

Table 5: “Eight ACs and Ten DCs” UHV power transmission projects of the State Grid. demand conditions in Japan is the social acceptance issue, which means that wind projects are not supported by local communities, because past projects in the early stage brought no benefits but created noise and landscape disturbance [81]. Nevertheless, both the Chinese and Japanese governments are applying certain regulations and policies to improve the demand conditions of domestic wind power. * Related and support departments. In contrast to China's booming wind turbine manufacturing industry, the wind power domestic market in Japan is small, because of immature market attractiveness and scale. Over the years, the Japanese power generation supply chain from resource acquisition to power generation to transmission and distribution has been monopolized by utilities [82] who show little interest in wind power projects with high construction costs, and intermittence and transmission problems. Moreover, the corresponding supportive policies of national government have not yielded the expected effects and response. In contrast, the support departments in China effectively respond to national policy, which improves the development process. * Firm strategies, structures and rivalries. Compared with wind power, nuclear power develops fast and occupies a key position in the Japanese energy structure. After the Great East Earthquake, Tsunami, and Fukushima Nuclear Plant disaster, Japan has started to pay more attention to wind power. The grid access problem is jointly faced by the Chinese and Japanese wind industries, and measures to handle intermittence and transmission issues are being explored at the same time. Offshore wind power is also popular in both Japan and China, and floating wind power technology has been developed in recent years with more attention in Japan. Japan has excellent performance in ES industry development. Japan's NGK is the world's first and only company to successfully commercialize sodium-sulfur batteries; its products account for the majority of the world's chemical energy storage market. In this regard, China also shows strong interest in the ES industry. * Government and opportunity. Compared with China's price and non-price policies, and large-scale financial support, Japan pays less attention to wind power. Japan has published a series of supportive policies, including the Sunshine Program, the Moonlight Program, the new Sunshine Program, and the Feed-In Tariff mechanism. But the budget for wind power in these policies was far smaller than that of solar or geothermal. The fifth Energy Basic Plan issued by the Ministry of Economy, Trade, and Industry in July 2018 reflects Japanese determination for renewable energy development, in which wind power might play a key role. * [6] Technology. China has a considerable number of wind turbine manufactures, and the installed capacity leads the world; however, China lacks the corresponding technical innovation and necessary patents, which is a high value-adding sector in the value chain. As the primary researcher of renewable energy, Japan owns a bunch of independent innovations and patents. As for new technical projects, such as offshore floating wind power, Japan also conducts numerous studies. The Japanese government has supported the development of ES technologies, and has obtained fine achievements. China should also increase the R&D strength of wind power and related technologies.
