Rajan responds, "I too like examining a country's steady state rate of growth, but I prefer to go deeper by examining the impact of various factors on a country's economy from the standpoint of the neoclassical model. Based on my readings and analysis of the macro-economic data, I came up with the following conclusions for the three countries where we hold significant positions."
Country X: It is experiencing a higher level of capital accumulation and a rapid increase in business investment. Taken together, these two developments indicate a higher growth rate of output and potential GDP.
Country Y: Its government is investing in advanced technologies and initiating measures to achieve growth in total factor productivity. Even though the country is experiencing diminishing marginal returns to capital, I believe it will be able to sustain growth in per capita GDP.
Country Z: Its data show increasing trends in the rate of savings, growth rate of the labor force, and the depreciation rate that, I believe, will result in a permanent improvement in the growth rate of output per worker.
Which of Rajan's conclusions regarding the neoclassical model is most accurate? His conclusions pertaining to Country:

A.Z. B.Y. C.X.解释：
Rajan’s conclusions pertaining to Country Y are most consistent with the neoclassical model. Because of diminishing marginal returns to capital, the only way to sustain growth in potential GDP per capita is through technological change or growth in total factor productivity. This change results in an upward shift in the production function—the economy produces more goods and services for any given mix of labor and capital inputs.
拉詹关于Y国的结论与新古典主义模型最为一致。
由于资本边际收益递减，维持潜在人均GDP增长的唯一途径是通过技术变革或全要素生产率的增长。这种变化导致了生产函数的向上移动——在任何给定的劳动和资本投入组合下，经济生产出更多的商品和服务。
