# Overview of Wind Power Industry Value Chain Using Diamond Model: A Case Study from China
## 1 Introduction
### Literature Survey  
Current research about the wind power industry mainly focus on the following three research streams. The first tries to analyze its development status, existing problems, and solutions from various angles [7; 15; 18; 19; 20; 23; 24; 25; 26; 27; 28]. [PERSON] et al. described the presentation of wind power in China considering its distribution, bases, installed capacity, power generation from the spatial perspective, and the environmental benefits [8]. [PERSON] presented an overview on current developments of wind energy, potentials, mismatching between the generating power, and installed capacities and future prospectus in China [29]. The second stream studies innovation and the improvement of key technologies to improve power generation, grid-connection, and wind-power consumption abilities [30; 31; 32; 33; 34; 35; 36; 37]. [PERSON] and [PERSON] reviewed the present situation of wind-energy reliability analyses [38]. [PERSON] et al. proposed a probability-based dispatch strategy for determining energy storage capacity, with consideration of wind and load fluctuation, to improve acceptance of

Finally, the third stream analyzes the wind power industry from the aspects of industrial chains, and explores ways to increase its competitiveness [40; 41]. [PERSON] et al. explored the dynamics of environmental turbulence and flexibility within the wind power industry chain, focusing on external factors of the industry, instead of internal factors or overall analysis [40]. They evaluated the wind power industry chain and examined its operation mechanism based on the supply, technological, and value chains, and indicated that China should change direction from emphasizing development speed to cultivating industry core competitiveness [11]. [PERSON] et al. identified factors that affected the flexibility level of the wind power industry chain [12]. The first and the second kinds of literatures failed to analyze wind power from the perspective of the industry overall, while the third stream failed to launch a comprehensive analysis of the wind power industry chain, focusing on both its overall value creation improvement and factors influencing its value creation ability; all studies failed to comprehensively analyze and review wind power industry value chain in China with a diamond model both to enhance the overall value creation ability of the wind power industry, and to improve industrial sustainability. In addition, [PERSON] [28] studied the wind power industry using the diamond model with a traditional industrial development angle instead of a focus on the value chain. [PERSON] [22] studied the value creation effect of the wind power industry value chain based on system dynamics, but ignored comprehensive analyses. Our literature survey shows that there is a gap in the academic field aimed at discussing wind power industry value chain in view of overall analyses via the diamond model. To fill this gap, this paper focuses on a value chain analysis of wind power industry; it begins by constructing a value chain model and introducing the diamond model for comprehensive analysis. This model is suitable for analyzing the mutual influences between elements and their influences on the wind power industry; it has been widely used in industrial comprehensive analyses. [PERSON] [28] used a diamond model to understand the status quo of the Chinese wind power industry. [PERSON] [42] identified and analyzed, with the diamond model, factors that had significant impacts on the development of China's PV power industry. [PERSON] [43] used the diamond model to analyze internal and external factors that had significant influences on the competitiveness of China's coal industry. The role of Multinational Enterprise (Mne) penetration and governance quality was studied with the diamond model by [PERSON] [44]. [PERSON] explored the success factors of the 'Night Markets' in Korea using the diamond model [45]. [PERSON] et al.
