1 Introduction

It emphasizes the core role of language in enterprises, especially in multinational corporations, where language is not only a communication tool, but also a key production factor that affects information integration, organizational profitability, and global business control coordination. The article points out that although language is crucial for a company's competitiveness, the current understanding and utilization of language resources in the business community are still insufficient. English, as an international lingua franca, plays a major role as a communication medium in multinational corporations, and its research contributes to the development of linguistic theories. The article proposes that expanding the research perspective from corporate business discourse to corporate language proficiency is a natural extension of ESP theory in the field of business, which helps to construct a key factor expression system that affects the practical application and output benefits of language.

2 Theoretical Review

In depth exploration of the theoretical foundations of language economics and language management, as well as their roles in building language competence in multinational corporations. Linguistic economics, as an interdisciplinary field that studies the relationship between language and economic variables, originated from Adam Smith's market language theory, emphasizing the value of language in reducing transaction costs and improving market efficiency. Information economist Jacob Marschak further discovered that language has economic characteristics, while Grin applied economic concepts to language research, establishing the research paradigm of linguistic economics. The current research focuses on the impact of individual language skills, language dynamics, reasons, and consequences. Language Management (LM) was founded by Neustupn ý and Jernudd, focusing on language issues in multilingual environments of multinational corporations, emphasizing the need for regulation and intervention of language as a knowledge resource. Spolsky defines language management as the effort to change language practices or beliefs. Language management theory focuses on small-scale real-time discourse correction and macro level ideological intervention, involving language norms, planning, education, and other aspects. Language economics and language management complement each other. The former provides a foundation for analyzing the value of enterprise language and management planning, while the latter focuses on the effectiveness and normative adaptability of language use, jointly analyzing the interaction mechanism between language and economic activities, and building enterprise language competence.

The value of corporate language emphasizes the economic attributes of language, viewing it as the ability to create market and social value, influenced by business management and demands, and reflected in internal and international communication. Language proficiency is an important component of a company's language ability and is positively correlated with its operational efficiency. Functional pragmatics practice focuses on the application and management of corporate language, dividing corporate language proficiency into business language and communication functional language. It emphasizes that language users in multilingual environments will flexibly adjust their language expression according to business needs and psychological factors. Language activity regulation involves language management ability, including macro level language strategy ability, meso level strategy execution ability, and micro level language practical ability, which together constitute the management perspective connotation of enterprise language ability.
