Noteworthy Discrepancies in China's GDP Accounting.

Consistency is essential in statistical data processing. This paper reports some notable discrepancies in China's GDP accounting, which are unexpectedly found after testing the consistency of GDP accounting and its components. Although these discrepancies are mainly attributed to the revision methodology adopted after the 2004 economic census, the intention to harmonize GDP accounting data, in terms of production and expenditure, also contributes to the discrepancies. Our finding highlights the need for careful checking of consistency and for testing before formal release of any official statistics. [ABSTRACT FROM AUTHOR]
