对于您的第一句话“经济学中没有人使用“实际GDP”这个概念。”我表示非常不理解。
real GDP是经济学上非常基础和常用的概念,本质上指的就是您所说的“以某年币值折算的GDP”,不知道您为什么说经济学中没人使用“实际GDP”这个概念?
在宏观经济学论文中,到处都能找到实际GDP这个词。我随便搜了一下最近AER上面的文章,比如:
Feenstra, Robert C., Robert Inklaar and Marcel P. Timmer. 2015. "The Next Generation of the Penn World Table." American Economic Review, 105(10): 3150-82.
这篇文章摘要第一句就出现了“real GDP ”这个词,全部摘要中一共出现3次。
We describe the theory and practice of real GDP comparisons across countries and over time. Version 8 of the Penn World Table expands on previous versions in three respects. First, in addition to comparisons of living standards using components of real GDP on the expenditure side, we provide a measure of productive capacity, called real GDP on the output side. Second, growth rates are benchmarked to multiple years of cross-country price data so they are less sensitive to new benchmark data. Third, data on capital stocks and productivity are (re)introduced. Applications including the Balassa-Samuelson effect and development accounting are discussed.
