美国著名经济学家萨缪尔逊曾经说:“二次世界大战后,经济学是经济计量学的时代。”回顾近半个世纪经济学的发展历史,我觉得此言不无道理。自从进入20世纪以来,各国的经济学家越来越重视用统计观察方法去得到经济理论概念,同时也注意用经济理论概念来影响统计观察方法。因此,在定性分析与定量分析的紧密结合中,逐渐在世界上出现了经济计量学时代。 The famous American economist Samuelson once said: “Economics is the era of econometrics after the Second World War.” Looking back on the history of the development of economics in the past half-century, I find it unreasonable. Since entering the 20th century, economists in various countries have paid more and more attention to using the statistical observation method to get the concept of economic theory. At the same time, they have also paid attention to using the concept of economic theory to influence the method of statistical observation. Therefore, in the close combination of qualitative analysis and quantitative analysis, the era of econometrics gradually appears in the world.
