The supposed evidence was wrong because 50 is the PMI’s dividing line not between growth and recession, but between accelerating and slowing growth. Indeed, for 19 out of the PMI’s 36 months of existence, the value has been below 50, while Chinese manufacturing growth has averaged 7.5%.
事实上，在此期间中国制造业以5—7%增长。这一想当然的证据是错误的，因为50是PMI的分界线，但它不是增长和衰退的分界线，而是增长加速和减速的分界线。事实上，在有PIM数据的36个月中，19个月的数值低于50，而这段时间中国制造业增长率平均为7.5%。
