A piece up on Bloomberg says:

China's frenzied stock market boom -- which soured in the second half of June -- helped drive a surge in financial sector growth that underpinned the economy's better-than-expected gross domestic product result.

  • Financial services surged 17.4% in the first six months from a year earlier
  • Exchanges and brokerages registered record trading volume
  • It was the stand out industry as real estate languished

The data underscores the fragility of China's economy as a rout that wiped out almost $4 trillion in market value may shake confidence in the sector. That could dent hopes for a pick up in the second half and mean further stimulus will be needed if Premier Li Keqiang is to meet his 2015 economic expansion target of about 7 percent.
