The study further investigates the value relevance of earnings and earnings
persistence for yearly data. The highest return and earnings relation is found in year 2008
while the highest earnings persistence is found in year 2007 for listed companies on the
SET and the SSE. In addition, the findings reveal that the significant difference of value
relevance of earnings between Thai and Chinese listed firms appears in year 2007, while the
significant difference of earnings persistence between listed companies on the SET and
the SSE is found in all years. That is, the value relevance of earnings of listed companies on
the SET is more than that of listed companies on the SSE in year 2007 whilst earnings
persistence of listed companies on the SET is more than that of listed companies on the SSE
for all years. The results in this paper will directly contribute to the accounting standard
setters for issuing the accounting standards and the regulators for issuing the control rules
including the investigation of accounting information quality of two stock exchanges.
