It is generally considered，In many theoretical branches in Western economics，Development Economics is the closest to China。Because，Development Economics takes economic development issues in developing countries as research objects，and China is a developing country。Careful studying Western Development Economics Textbooks will discover，They have a distance with the actual development and development of China's economic reform and development。

The reason why this is so，Because on the one hand, the development economics from the middle of the 20th century is based on Western mainstream economics，The industrialization and modernization of developed countries in the west，And these theories and experience are in the background of the Western system、The development of cultural environment and economic conditions。Although many of them can learn from developing countries and even learn，But after all, they are not "native" in developing countries，This is inevitable to form. "It seems like this，But the feeling of not exactly is the case "。

On the other hand，Development Economics in the second half of the 20th century of its generation and development，mainly based on Latin American countries and South Asian countries as the research object。Although some developing economists studied the development of "Asian Four Little Dragons" including Taiwan and Hong Kong in Bet365 app download the 1990s，Later, I started to study the economic development of Mainland China，But they rarely study the perspective of "developing big countries" including the economic reform and development of great powers, including China。China as a big development country，Successful development experience since the reform and opening up、Miracle of long -term high -speed growth，Small space in Western Development Economics works。This cannot be said to be an important lack of development of economics。Different national conditions and development conditions in large and medium -sized countries，Put the same theory、Development Strategy and Development Policy Suggestions are provided to different developing countries，It is inevitable that "a set of clothes for everyone to wear" is unavoidable。

　Where to develop economics

Mr. Zhang Peang has repeatedly called on "Development of Daboles to become an important research object for developing economics"。"Economics of the Great Power" (editor -in -chief of Ouyang Yan，October 2019 edition of Renmin University of China Press) responded to Mr. Zhang Peang's appeal。The book follows the idea of ​​"developing and big countries in the development of economic sciences"，Incorporate national scale factors into development economics research，The logical system of the development of economics for the development of great powers，Dedicated to realize theoretical innovation of development economics，Make a Chinese scholar's own contribution。

Economics is essentially a logical system that explains socio -economic Bet365 app download phenomena，Its usefulness often depends on the importance of the explanatory phenomenon and the degree of appropriateness of the interpreted object。The original intention of the creation of economics，Refine the development model of developed countries and some Latin America and South Asian countries after World War II into theory and policies，To guide the economic development of developing countries。But，The 1970s and 1980s，Some developing countries guided by this theory encounter difficulties，Even caught in a "secondary income trap"，So that economists have a question of "where to develop economics"，Some even claim that "development economics has failed"。Since the end of the 20th century，Emerging powers represented by China have achieved continuous economic high -speed growth，The status of the world economic pattern is increasingly prominent，The academic world begins to explain this important economic phenomenon from different angles，A comparative advantage theory appeared、The theory of post -sending superior doctrine。You can see from the practice of developing countries，The factors that promote the rapid economic development of these countries are not a single，but comprehensive，In addition to comparative advantages and post -development advantages，National scale factors become an important influencing factor。Emerging great powers rely on the huge local market size and population scale，It can cultivate huge industrial clusters and complete industrial chains。This book is the characteristic facts based on the rise of the economic rise of bet365 Play online games the emerging country，Especially the successful experience of China's economic development，Big Development of Dapita as a research object，Try to raise these successful experiences into theoretical and principles that have universal significance，From a new perspective and direction，Theoretical innovation of developing economics。

　Basic features of the big country economy

Marx said: "Analysis of economic forms，Neither a microscope，You cannot use chemical reagents。Both must be replaced by abstraction。"The practice of the development of major powers provides new materials for the new development of economic development。But，To make the correct theoretical summary from complex practice，It must rely on a highly abstract thinking ability，Use comprehensive and induction analysis method。

The whole book makes a useful exploration in this regard: from the diversity characteristics of the large and great economy，Through abstract summary，Starting from the two initial characteristics of the population scale and land area，summarized its typical features。That is the scale of the market size and endogenous、The heterogeneity and adequacy of the endowment of the element、The diversity and hierarchy of the economic structure、The integrity and independence of the industrial structure、Difference and complementarity of the regional economy、Stability and persistence of economic development。Through higher levels of abstract thinking，revealing the basic characteristics of the economy of the country: First, the scale features，The overall size and scale of the economy of the great country's Bet365 lotto review economy、Market size and industrial scale huge。The second is multiple features，That is the big country technology、Industry、Multi -level structures formed by the differences in the development of regions and urban and rural development。This is the highest -level feature abstracted from the typical characteristics of the great country's economy。Books found some economic laws or universal things for the development of large powers through in -depth research，Put forward the theory of great domestic ability and the comprehensive advantage of great powers: The former refers to the advantages of super large -scale countries due to rich resources and broad markets，Relying on domestic resources and domestic markets can promote the independent coordinated development of the economy; the latter refers，You can integrate various favorable resources through the integration of large powers，Forms a comprehensive advantage that integrates multiple advantages。These two basic principles，The theoretical summary of the abstract analysis of the economic development law of the great country，It is suitable for theoretical analysis of the economic development of the country。

Scientific theory should enhance academic influence，It is necessary to build a distinctive discourse system; and the consistency of logic and history，The basic principle of building an academic discourse system。This book defines the concept of developing big powers through definition，Selected specific research objects，Disposal the characteristics of the economy，Summarize the principle of economic theory of the country，Bet365 lotto review Put forward the strategy of economic development of the great country，Forms the prototype of the theory of developing economics。In this system，The key problem is the choice and setting of the logical starting point。Book thinks，The scale characteristics are the core features of the economic economy，scale category is the key to understanding the economic advantages of great powers，Diverse structure is the iconic feature of the development of the country's economy，Structural category is the key to understanding the economic transformation of the country in the development of the country。

Based on this，The author believes that scale and structural problems are the basic issues of the development of the country's economy。After setting this logic starting point，Starting from the scale category，It can gradually show the population scale and land scale to the market size、The evolution process of industrial scale and enterprise scale，to form the advantage of economic development of the country，and implement the corresponding development strategy。Depart from the structural category，It can gradually display from factor structure to industrial structure、Urban and rural structure and regional structure，The evolution process of modern economic structure，3979_3999。The author takes scale analysis and structural analysis as the main line，Study the Economic Development Elements of the Great Power; based on scale analysis and structural analysis，Study Strategy for Economic Development of the Great Power，Therefore, through the logic chain of scale and structure，Bet365 app download Constructing the theoretical system of developing economics for great powers。
