In the fields of digital economy, new energy, low-carbon economy and bioeconomy, a number of rapidly developing emerging industries have emerged. Driven by the goal of global low-carbon transition and carbon peak carbon neutrality, the new energy industry has become one of the fastest growing and most promising emerging industrial tracks. This paper takes the development strategy of Tesla’s new energy vehicles as the research object, and enriches the relevant theories of enterprise internationalization through data analysis and questionnaire survey. As the world’s earliest brand of new energy vehicles, Tesla has a number of patented technologies in the field of new energy, and its sales are the first in the world. Its strategic management mode is representative and instructive. This paper analyzes the existing problems and causes of Tesla in marketing environment, consumption status and original development strategy, and uses SPACE analysis to study new marketing strategies and safeguard measures, which provides examples for the strategic layout of the enterprise and attempts and references for promoting the development strategy innovation of the automobile market in the new economic era. First of all, according to the development of Tesla new energy vehicle enterprises, combined with the strategic theoretical basis and relevant literature review, the internationalization strategy development theory and enterprise internationalization model are sorted out. After summarizing and analyzing various data of Tesla and demonstrating the assumptions of Tesla’s internationalization strategy, this paper believes that Tesla's future development needs to solve potential problems such as product quality risks and customer after-sales maintenance, and on this basis, deepen the internationalization of the company to achieve better performance (An Emerging Middle Class.
