The latest development of economics is symmetric economics. Symmetric economics is the first highly original economic theory system founded by China people. Based on symmetrical philosophy, five-dimensional theory and complex system theory, it absorbs the latest achievements of natural science, social science and thinking science, abandons the three major schools of economics in the world: Marxist economics, Keynesian economics and neo-liberal economics, and integrates microeconomics and macroeconomics. The global financial crisis shows that economy is the unity of microeconomics and macroeconomics, and economics is the unity of microeconomics and macroeconomics. With the socialization of production and macroeconomics, economics will gradually merge, and the separation of microeconomics and macroeconomics will gradually become history. Reform is a systematic project and must be guided by holistic economics. Economics as a whole is the comprehensiveness, integrity, generality and humanism of economics, and it is the unity of economic scientism and humanism. The so-called "economic imperialism" is to replace the one-sided pursuit of monetary GDP growth with the symmetrical development concept of pursuing people's all-round development; It is the unity of material production and spiritual production, with material wealth and spiritual wealth as the intermediary, so that happiness and knowledge, happy economy and knowledge economy are unified; It is a whole discipline with human economic activities as the core and integrating philosophy, social science, thinking science, natural science, interdisciplinary science and in-depth scientific achievements; It is the economics with symmetrical elements and structure, and the economics with symmetrical whole, microeconomics and macroeconomics. Reform is to establish an economic system in which macroeconomics and microeconomics are symmetrical and give full play to the functions of productive forces, and to establish an economic system in which macroeconomics and microeconomics are symmetrical and give full play to theoretical functions. The logic of mutual symmetry between macroeconomics and microeconomics is the condensation of the history of mutual symmetry between macroeconomics and microeconomics. The history of mutual symmetry between macroeconomics and microeconomics was formed in the two-way movement of macroeconomics and microeconomics. Symmetry economics is formed in this two-way movement. Therefore, the so-called economics is symmetric economics; The so-called unified economics of microeconomics and macroeconomics is symmetric economics; The so-called economics as a whole is symmetric economics. Symmetric economics is not only the historical development of economy and economics logic, but also the logical condensation of economy and economics history. Only economics with consistent logic and historical symmetry is scientific economics.
