中日经济差距到底有多少年?这是个由来已久的话题。2001年的时候,日本经济产业研究所的关志雄先生说至少40年;笔者认识的一位日本经济学教授在跑遍了大半个中国后感慨地说:“说差距有100年有些夸张,差距有50年有些保守,应该差距在80年左右吧!”作为经济学家,会通过GDP、平均寿命、婴儿死亡率、第一产业占GDP的比重、城市的恩格尔系数和人均电力消费量等方面的各项数据进行科学分析后得出自己的结论。但笔者想从科技的角度来探讨一下。 How many years has the economic disparity between China and Japan in place? This is a long-standing topic. In 2001, Mr. Kwan Chih-hung of Japan’s Institute of Economics and Industry said that for at least 40 years, one Japanese economics professor who I met after running over half of China said with emotion: “There is some exaggeration over a 100-year gap. The gap Some 50 years are conservative, and the gap should be around 80 years! ”As an economist, through GDP, average life expectancy, infant mortality, primary industry’s share of GDP, city’s Engel’s coefficient and per capita electricity consumption After the scientific analysis of the various data to reach their own conclusions. However, I would like to explore from a technical point of view.
