从战后美国称霸世界经济到世界经济多极化发展,从内燃机的发明到今天互联网的发达,科技成为推动经济发展的第一动力,思想与知识的繁花也竞相开放。宏观经济学作为一学科虽然诞生不过百年,但它对近现代经济的影响却非同小可。社会在进步,应用其上的理论也要直视缺陷、更新完善才能发挥良好的指挥作用。如今透过困境去反思现代宏观经济学,吐故纳新,结合新技术进行修正方能降低风险、实现突破。否则,导致全球经济繁荣逆转至今仍未恢复的美国次贷危机还会不停地上演。债务困境——宏观经济学并不完美 From the invention of the internal combustion engine to the development of the Internet today, science and technology have become the number one motive force for promoting economic development since the post-war United States dominated the world economy to the multipolarization of the world economy. The blossoming of ideas and knowledge also competed with each other. Although macroeconomics is a hundred years old as a discipline, its influence on the modern economy is not trivial. In the process of social progress, the theory applied to it must also look directly at the defects and improve and perfect it so that it can play a good role in command. Now through the plight of the reflection on modern macroeconomics, make new discoveries, combined with new technologies to correct before they can reduce the risk and achieve a breakthrough. Otherwise, the subprime mortgage crisis in the United States, which led to the reversal of the global economic boom so far, will continue to unfold. Debt Dilemma - Macroeconomics is not perfect
