Big data analysis helps improve regulators' work

Information technology and big data analysis are becoming increasingly effective tools for the nation's securities regulator to identify and crack down on insider trading.

The China Securities Regulatory Commission said on Friday that it had identified 375 insider trading cases through big data analysis since mid-2013, up by 21 percent from the previous 18-month period.

Among the cases, 142 have been officially investigated by law enforcement authorities, up 33 percent, according to the CSRC.
