查了一下最早出处是Roubini这老匹夫。

里面说的就是环比：

“China is in a recession regardless of what the highly massaged official numbers claim,” Roubini, a professor at NYU’s Stern School of Business and the chairman of consulting firm Roubini Global Economics, wrote in a note today on his Web site. “When growth is slowing down sharply the Chinese way to measure GDP is highly misleading.”

Unlike the U.S. and western Europe, China’s figures on gross domestic product measure growth from the same quarter a year ago rather than the previous three months. The year-on-year figures fail to capture the economy’s slowdown at the end of 2008 because growth was so high in the preceding quarters, Roubini wrote

我发现只要是涉及到中国，不管什么本来多严谨的学者都要失常。你说中国环比下降，起码也要算一下吧。你不算，也不能上来说recession啊，按照西方定义那个是要连续两季下降啊。
