1 Introduction

Spanish, as the official language of 21 countries, is spoken by approximately 600 million people worldwide, accounting for 7.5% of the world's population. Academic research focuses on the historical context and the formation process of 'Pan Spanish ism'. Spain holds a central position in the global promotion of Spanish language, with the Royal Language Institute being the highest institution for language planning. Previous studies have mostly focused on micro level language standardization strategies, lacking a comprehensive discussion on the language planning behavior of the Royal Language Institute in the Spanish speaking world. This article proposes a theoretical model of language international communication and analyzes the role transformation of the Royal Language Institute in different stages of Spanish language international communication. With the development of the situation, the role of the Royal Language Institute in the international dissemination of Spanish is becoming increasingly diversified, both defending the reputation of the official language and maintaining the "unity in diversity" of language variants, expanding the global competitiveness and influence of Spanish.

2-Language International Communication Model

We discussed the model of international language dissemination and emphasized the importance of language promotion in maintaining cultural diversity and promoting international understanding. The "push-pull model" proposed by Zhang Zhiguo divides language dissemination into two stages: external promotion and external dissemination, in which the "push" of the promoting country and the "pull" of the importing country work together. Language promotion involves the planning subject's allocation of functions, status, and resources for different languages, while the response of the input country to foreign languages is diverse. The game between the promoting country and the importing country is not zero sum, but a win-win situation achieved through negotiation and cooperation. Based on the cooperative game model and international language communication experience, this article constructs a 2 × 2 game matrix to analyze the behavior patterns of promoting countries in different quadrants. From the autonomous development of language in the third quadrant, to the promotion of colonial language in the second quadrant, to the flexible promotion of dominant language in the first quadrant, and the decline period of promotion in the fourth quadrant, the dynamic process of international language dissemination is demonstrated.

3. The Role Transformation of Spanish International Communication and the Royal Language Institute

Explored the historical evolution of the international dissemination of Spanish and the role played by the Royal Language Institute in it. Since the late 15th century, the promotion of Spanish has undergone a transition from strong promotion to flexible promotion. The Royal Language Institute plays a key role in language planning, including ontology planning, status planning, acquisition planning, and reputation planning, maintaining its influence in the Americas through language and cultural ties.

4 Conclusion

The Royal Language Institute has been established for over 300 years, dedicated to maintaining the purity of the Spanish language, protecting literature, and promoting cultural development. With the independence of American colonies, Spanish became a link between the two sides of the Atlantic, and language promoting countries and importing countries entered into a deep game. In the second half of the 20th century, the Spanish linguistic community and intellectuals dominated the debate on language division and unity, and the stance of maintaining language unity was responded to by American countries. Multicentrism and Pan Spanish ism became the guiding ideology of the academy. In the 21st century, American countries have risen in terms of population, economy, technology, cultural dissemination, and other aspects. The growth of the Latinx population in the United States has pushed Spanish identity towards the Americas. Language policy has become a national policy in Spain, and the activities of the academy have received support from the royal family and government. The college adjusts its strategy, adheres to its identity and status planning, expands its functions, and uses new technologies to consolidate its discourse power. The spread of Spanish in the Americas has experienced strong colonial promotion and flexible game promotion after independence. The future trend of declining dominance of promoting countries and increasing autonomy of importing countries is still unclear, depending on the outcome of the game between language groups and planning subjects.
