Many scholars have studied the innovation of e-commerce.Scholar Rahman S has discovered that e-commerce innovation and e-service quality can improve customer satisfaction and loyalty, respectively.This research helps to enhance the novelty related to e-commerce innovation [1].Scholar Jeong H proposed a new innovative business model of e-commerce platform, through the use of digital dual technology to combine real-time commerce with the meta-universe, overcoming the limitations of existing online shopping [2].Scholar Mangiaracina R Scientific publications aimed at improving the efficiency of innovative solutions for business-to-consumer (B2C) e-commerce last-mile distribution review and classification [3].However, in practice, how to apply the concept of STEM education to the cultivation of cross-border e-commerce students' innovation ability requires further research and exploration.
Therefore, this study aims to explore the innovation ability training method of cross-border e-commerce students based on STEM education concept, and to verify its effectiveness and feasibility through empirical analysis.This study will use a combination of case study and questionnaire survey to explore the practice of cultivating students' innovation ability.The research results will help to provide new ideas and methods for cross-border e-commerce education, and also provide reference and reference for the application of STEM education concept in practice.

Introduction to STEM Education Concept
STEM is a comprehensive educational concept [4][5], and its goal is to cultivate students' subject literacy and comprehensive literacy [6][7].STEM education emphasizes students' active participation in practical inquiry, teamwork and innovative thinking [8][9].The core of the STEM education concept is to combine subject knowledge with practical problems, and cultivate students' innovation ability through practice and inquiry.
The application of STEM education concepts has been widely recognized and applied.The practice of STEM education can enhance students' teamwork spirit and improve students' sense of innovation.The practice of STEM education can help students better adapt to social changes and development in their future careers.In cross-border e-commerce education [10][11], the application of STEM education concepts can enable students to have a deeper understanding of relevant knowledge and be able to apply it, thereby improving students' ability to use it.

Application of STEM Education Concept in Cross-Border E-commerce Education
Although STEM education and cross-border e-commerce education are two different fields of education, there is a certain connection between them.STEM education can be applied to instructional design to help students better understand and apply relevant skills.The practice of STEM education can strengthen students' practical ability and professional literacy [12][13].
The application of STEM education concept in education is as follows: First of all, STEM education can help students to better understand and apply cutting-edge related skills.STEM education emphasizes practical inquiry and interdisciplinary integration, which can help students better understand subject knowledge.At the same time, STEM education focuses on students' active participation and teamwork, which can cultivate students' practical ability and spirit of cooperation, and provide support for students to apply related knowledge to practical issues.
Secondly, STEM education can help students discover problems, solve problems, and innovate.
The practice of STEM education can cultivate students' innovation awareness and innovation ability.
Finally, STEM education can strengthen students' practical ability and professional literacy.STEM education focuses on practical inquiry and interdisciplinary integration, which can help students better cope with complex issues.The practice of STEM education can also strengthen students' professional literacy.
In summary, the application of STEM education concepts in education can help students better understand and apply the relevant knowledge and skills of cross-border e-commerce, strengthen students' practical ability and professional literacy, in order to improve students' competitiveness and application ability in the field of cross-border e-commerce.

Application of STEM Education Concept in Innovation Ability Training
STEM education emphasizes practical inquiry and interdisciplinary integration, focusing on combining subject knowledge with practical problems.In practice, students can better apply the knowledge they have learned, explore the nature of the problem, and propose innovative solutions to cultivate students' innovative ability.Therefore, the concept of STEM education plays an important role in the cultivation of innovation ability, as follows: Encouraging students to take the initiative to explore and practice: STEM education emphasizes students' active participation, practical inquiry and independent learning, allowing students to continuously explore and solve problems in practice, so as to cultivate students' innovation ability.
Cultivating interdisciplinary and comprehensive literacy: STEM education covers many subjects, emphasizing the cultivation of comprehensive literacy.This interdisciplinary approach to education can cultivate students' comprehensive thinking and ability, and provide students with a broader vision and ideas in innovation.
Encouraging the solution of practical problems: STEM education focuses on combining subject knowledge with practical problems to encourage students to solve practical problems.This kind of practical education method can allow students to better apply the knowledge they have learned and improve their innovation ability.
Emphasizing teamwork and communication: STEM education emphasizes teamwork and communication, allowing students to solve problems together in cooperation, so as to cultivate students' teamwork and communication skills.This kind of teamwork can stimulate students' innovation potential, but also allow students to learn to listen to and respect the opinions of others, and strengthen students' communication and collaboration skills.
In summary, the STEM education idea is very important in the cultivation of innovation ability.The educational method of STEM education can help students take the initiative to explore and practice, cultivate interdisciplinary comprehensive literacy, encourage the solution of practical problems, and emphasize teamwork and communication.
