| The financial industry is undergoing significant changes due to the widespread use of digital technologies such as big data,blockchain and cloud computing.digital economy has become a key force in restructuring factor resources and reshaping economic structure.The automotive industry is facing unprecedented changes,and digital transformation has become the most basic and bottom change that will profoundly affect the development of enterprises.Enterprises in the automotive industry chain have increased investment in the digital field,while the wide application of digital technology in the automotive industry has also promoted the development of digital technology in the automotive industry.When digital transformation,enterprises need to consider how to use digital resources to effectively optimize and upgrade each link in the value chain to achieve process optimization and system management in order to achieve concrete results of digital transformation.Based on this paper,taking Changan Automobile in the automotive industry as an example,the value chain is used as a deconstruction perspective,and The Case Study Method is employed to explore the Digital Transformation of Enterprises,analyzing the optimization of their Value Chain at each stage,and the impact of Digitalization on their Performance.it can help similar enterprises understand the digital transformation process of different links in the digital transformation process,and in addition,This paper investigates the impact of digital transformation on enterprise performance by using internal and external value chain performance evaluation indicators and the Data Envelopment Analysis(DEA)model.It also examines the variations in the degree of influence of digital transformation on enterprise performance at different stages,and help enterprises make targeted reference.This paper finds that,based on an internal and external value chain perspective,digitalization can be enhanced by optimizing or innovating internal value chain links and participating in value co-creation with external upstream and downstream associates.Through the transformation of the whole value chain of research,production,supply and sales,daily operation and consumer data can be monitored and analyzed in real time,and the data can be fed back in a timely manner to make the enterprise operation and management accurate and efficient.This has dramatically changed the traditional business model,resulting in lower costs and significantly higher efficiency and quality throughout the automotive value chain.However,the emergence of transformational economic benefits usually requires a certain period of transformation shock.After that,digital transformation will have some enhancing effect on business performance.This paper provides valuable insights into the digital transformation of enterprise value chain and enterprise performance under the backdrop of big data.Manufacturing enterprises can use digital value chain benefits to achieve digital transformation. |
