| As society continues to progress and the economy continues to develop,primary energy sources,represented by oil,coal and natural gas,are more scarce than ever before.In addition,the inappropriate use of energy by humans is causing many environmental problems.Against this background,China is placing increasing emphasis on the development and use of new energy sources.New energy is a renewable energy source and its use can alleviate the problem of resource constraints in China,while avoiding environmental pollution and achieving sustainable development.Company G is a wind power equipment manufacturer,specialising in the processing,manufacture and sale of wind power blades,and has grown rapidly in recent years to become a leading company in the wind power equipment manufacturing industry.Company G is a case study to help deepen the understanding of the wind power equipment manufacturing industry.In this paper,we analyse the existing profitability model of wind turbine blade manufacturing company G on the basis of the current situation and theories at home and abroad,and use literature analysis,case study and comparative analysis to analyse the existing profitability model of the company.On the basis of this,we explore the problems of Company G’s profitability model and put forward suggestions in response to the problems,and also hope to have some reference significance for the development of the same industry.In the theoretical part,the background and significance of the research,research ideas and methods are firstly introduced,followed by the current status of the research on profitability models by domestic and foreign scholars,and finally the concept of profitability models,the components of profitability models and the concepts of Du Pont analysis used in the research are summarised according to the research theories on profitability models by domestic and foreign scholars.These theories are used to provide theoretical support for the case studies that follow.In the case study section,the company profile,the entire business process of the wind power industry and the position of Company G in the industry chain are firstly introduced,followed by a detailed analysis of the current situation of Company G’s profitability model in terms of its components and aspects.Then the company’s profitability model is evaluated in terms of financial indicators and sustainable development,problems in the profitability model are identified and targeted optimisation measures are proposed to provide some ideas on how to achieve more sustainable profitability for wind power industry related enterprises. |
