In a mature economic policy system and economics education system, the economic theory must be more realistic, and economic policy must be based on theoretical logic. However, the combination of this theory and reality should rely on the expansion of the discipline's territory and theories. The progress of science and technology depends on the scientific division of labor and professional positioning, rather than on the ability or role of individuals. What's wrong with this text? ['Economic theory cannot make positive economic policies without facing reality.', 'Economic policy as a combination of economic theory and reality cannot be formulated based on the role of economists.', "The combination of economic theory and reality should be based on the expansion of the discipline's territory and theoretical progress.", 'The ability to formulate a sound economic policy depends on the ability of the economist.']
