[EN] Türkiye Manufacturing Purchasing Managers’ Index (PMI) published by Istanbul Chamber of Industry and Purchasing Managers’ Index (SAMEKS) released by Independent Industrialists’ and Businessmen's Association are among the important survey indicators which are monitored in order to obtain information about the course of economic activity. Although these two important indices have moved in tandem historically, it is observed that they have diverged from each other in some periods, more visibly in recent years. In this study, after examining the sources of this divergence under different headings, the relationship of both of these indices with the manufacturing industry production is examined with threshold value analysis. Accordingly, it is observed that the fixed threshold value for PMI is below 50 (47.9), and no statistically significant coefficients could be obtained in the analysis conducted by SAMEKS industry index. In addition, it has been detected that the change of the index as well as its level is critical when interpreting the relation between PMI indicator and the manufacturing industry. In sum, the analysis results imply that a holistic view of survey indicators is important as well as headline value.
