Growth rate of labor productivity= Growth rate of TFP+ Growth rate of capital deepening，capital deepening%=△y/y-△T/T

Baseupon Exhibit 1, capitepening a sourof growth wmost important for: A.Country B.Country C.Country A is correct.The associate economist cmeasure the effeof pure capitepening measuring the fferenof the growth rates of labor proctivity antotfactor proctivity (TFP). The larger the fference, the more important capitepening is a sourof economi growth. From 2000–2010, Country A’s labor proctivity grew 2.4% per year, of whi0.6% came from TFP growth an1.8% from capitepening (2.4% – 0.6% = 1.8%). 考点Cobb-uglproction function 的变形公式解析先写出变形公式一国人均产出也就是劳动效率的增加来自于两个方面资本深化以及技术的进步Growth rate of labor proctivity= Growth rate of TFP+ Growth rate of capitepening（假设劳动力恒定不变）capitepening%=△y/y-△T/T最后计算结果是A国的数值最高(2.4% – 0.6% = 1.8%).这就表明A国对于资本深化最依赖，资本深化对于该国经济增长的贡献最大。 上课讲的第一个变形公式是乘积形式y=T·k的阿尔法次方，这道题又进一步变形为加和的形式？
