The character "Yuan" is a very important and auspicious character in China。The character Yuan in the oracle bone inscriptions is the “head” of a person，"Erya" defines the meaning of Yuan as "head"，"Shuowen Jiezi" defines the meaning of Yuan as "beginning"；In the "Book of Changes", "Yuan Henry Zhen" is often used to explain the hexagrams，The original meaning of Yuan is "Da" Shi" and "Ji"，Therefore, the compound words of Yuan in Chinese are such as Yuan Qi、New Year's Day、Head of State、记元、Kaiyuan, etc. all have extremely important meanings。So what is "meta-theory"？The Greeks were the first to use metaphysics to express the unclear objects of physical research，So meta means "after..." and "beyond..."，Metaphysics is the knowledge “after physics” or “beyond physics”。From this，Metatheory is considered to be “a theory that explains the premises of a theory”, “a theory about a theory”, and “a theory that serves as the foundation of a discipline”，It refers to the theory in the philosophical sense。Different from general theories that form a system by demonstrating the correlation between concepts，Metatheory is to question the "meta-concept" of subject theory，Questioning the premises of normative theory，Verify the ontology of theoretical research，Form the ontological basis that supports the discipline。For example, "metapolitics" usually refers to political philosophy，It is different from general political thought and political theory，But to ask what politics is，Discover the “political nature” of people。Similarly，The meta-theory of national bet365 new customer offer generally refers to bet365 new customer offer philosophy，It is not an indicator provision for safety theory or an operational guidance for safety practice，But to question the essential meaning of “country” and “bet365 new customer offer”，Elucidate what kind of “reality” national bet365 new customer offer is and its ontological basis，Elucidate the essence of national “bet365 new customer offer”，Core concepts of national bet365 new customer offer、Preliminary exploration of basic assumptions and basic propositions。

　　First, metatheory focuses on the meta-concept of a theory.The object of national bet365 new customer offer research consists of two meta-concepts: "state" and "bet365 new customer offer"。A country is a territory、Population、Culture、A collection of resources and legal power，Usually a legal entity that exercises sovereignty；Safety is objectively no threat、No subjective anxiety、Conflict-free state and ability between subjects；Meta-theory needs to explore the essential meaning of these two meta-concepts。Based on the concept of country，It is also necessary to clarify the connotation and types of countries，such as nation-state、Civilized country；Modern country、Traditional country；Developed countries、Underdeveloped or developing country；First World Country、Second World Country、Third world countries, etc.。Based on the concept of bet365 new customer offer，It is also necessary to clarify the bet365 new customer offer connotation and its type，such as broad sense bet365 new customer offer and narrow sense bet365 new customer offer，Absolute safety and relative safety、Positive bet365 new customer offer and negative bet365 new customer offer、Intentional safety and unintentional safety, etc.。Another extension of safety，There are also complementary concepts related to bet365 new customer offer such as deterrence or shock、Strategy or strategy、Containment or prevention and control；Parallel concepts such as power、Sovereignty、Government、Agree、Community；Competing concepts such as peace or safety、Risk or danger、Threat、Emergency or crisis, etc.。If associated with a horizontal realm，Combining the diverse scenarios where traditional bet365 new customer offer and non-traditional bet365 new customer offer are intertwined，Then a “concept group” related to national bet365 new customer offer can be formed，Perform an overall structural analysis on this，It can reveal the uniqueness and richness of the genealogy of subject research objects。

　　Secondly, metatheory explores the ontological basis of the theory.Metatheory as “theory of theories”，The "ontology" of national bet365 new customer offer research needs to be elucidated，Exploring what kind of “reality” is national bet365 new customer offer？Objective realism believes，Safety is an objective reality，bet365 new customer offer threats are entirely objective and assessable，National bet365 new customer offer is an objective state without danger or threat；Subjective realism believes，Safety is subjective，It is a subjective reality that is difficult to evaluate，National bet365 new customer offer is also subjective，And national decision-makers’ subjective perceptions of bet365 new customer offer directly govern national bet365 new customer offer decisions，Thus affecting or changing the actual bet365 new customer offer status；Subjective-objective realism holds a dualistic position，Considering that national bet365 new customer offer is an objective existence，It’s also a subjective feeling，Or it is the result of the interaction between subject and object。Discursive realists go beyond the objectivity of bet365 new customer offer reality、Subjective、Subjective-objective cognitive level，Considering safety is a specific speech act and discourse structure，National bet365 new customer offer is no longer a simple analysis of the threats facing the country，It is an exploration of how a country’s specific identity is produced and reproduced。Intentional realism goes further than discourse realism，Considering bet365 new customer offer as “intentional reality”，National bet365 new customer offer is a "social wave function" in which multiple possibilities are superimposed。

Actually，The essence of a country is the same as the essence of human beings，As Marx said，“The essence of man is not an abstraction inherent in a single person，In its reality，It is the sum of all social relations”。From the perspective of general bet365 new customer offer theory，bet365 new customer offer is always presented as a "relationship"。In the inheritance of Chinese culture，The world where nature and man are one is a world composed of relationships，It is relationships that construct the world, not the other way around，When used in international relations, relationships construct countries and national bet365 new customer offer。So，Anything objective、Subjective、Subjective-Objective、Discourse、The "reality" of intentionality，Can be classified into generalized relationships of different levels and types，In other words, the general bet365 new customer offer theory adheres to the "relational ontology"，The essence of national bet365 new customer offer is “relationship”，The ontology of national bet365 new customer offer studies is “relational reality”。From the perspective of power politics，Countries in an alliance are more likely to participate in the alliance's international conflicts，Even alliances sometimes transcend geographical relations to pursue national interests；From the perspective of capital politics，Between countries that have completed industrialization and those in the process of industrialization，Will be due to industry competition、Business competition and even overall industrial competition will trigger more competition among countries、Conflict and even war。

　　Finally，Metatheory sets the premise of normative theory and applied theory。Theoretical construction can generally be divided into meta-theories、Gauge theory、Three forms of applied theory，Metatheory is the "foundation" of the entire theoretical building，Each of the three forms has its own theoretical mission，They form a relationship that is both independent and promoting，Their formation and development are often a sign that a discipline is gradually maturing。Meta-theory clarifies the meta-conceptual meaning and ontological premise of national bet365 new customer offer，Normative theory makes appropriate provisions for subject theory based on meta-theory，And use this value scale to determine and correct the research objects and related issues，For example, constructing basic principles for assumptions such as "relational reality" and the state as a "rational actor"；Carry out academic and rational analysis on the evolution of national bet365 new customer offer, its variable structure and characteristic theories；Based on the empirical facts of national bet365 new customer offer，Deducing safety regulations and instructions that can guide behavior from general principles；Summary and classify the theoretical demonstration and practical operation of safety principles and norms, etc.。Applied theory refers to empirical evidence based on the close integration of theory and practice、Operationable knowledge system，The applied theories of national bet365 new customer offer are more based on normative theories to answer and solve cutting-edge issues and challenges in national bet365 new customer offer practice，Not only must embody the essence of general theoretical laws and models，And we must form an early warning system to safeguard national bet365 new customer offer、bet365 new customer offer approach、Weighing mechanism、Behavioral rules and operating procedures, etc.。In view of the "global nature" of bet365 new customer offer research，The applied theory of national bet365 new customer offer can form many branches and topic types。

The “meta-theoretical” construction of national bet365 new customer offer studies is increasingly valued by scholars of international issues studies。Like Barry Buzan、Alexander Winter and other scholars have discussed it。Chinese scholars have also made valuable discoveries，As Wang Jisi clarified "safety、Wealth、Freedom、Justice and faith” are the five ultimate goals of world politics，Safety is the primary goal。Wang Yizhou proposes a new aspect of bet365 new customer offer research: diversifying target groups、Open format、Integration of issues、Complexity of concerns、Diversification of actors and non-monopoly of resources, etc.。Some scholars have expanded on the core concepts of bet365 new customer offer、Research on basic assumptions and basic propositions，For example, Zhang Yuyan and Feng Weijiang demonstrated that the state is a rational actor，bet365 new customer offer interests are the country’s first need，Safety costs follow basic safety assumptions such as the law of diminishing marginal returns；Proved that absolute bet365 new customer offer cannot be achieved，Increasing investment in absolute bet365 new customer offer will lead to bet365 new customer offer dilemma，The country’s pursuit of relative bet365 new customer offer should end with balanced bet365 new customer offer，The key to building a community with a shared future for mankind is "Dayu's improvement" and other important bet365 new customer offer propositions；Another example is the proposition put forward by the author of this article: bet365 new customer offer is the "optimal coexistence" between actors，The core of the harmonious paradigm is "shared bet365 new customer offer" etc.。
