China's innovative investment model in infrastructure constructions – start construction on debt and repay after completion – has been benefiting the speedy urbanization development in the past decades, executive of Dalian Wanda Group said on Sept 15.

"Without social capitals in infrastructure construction, China might never develop at the current paces with the treasury funds only," Chairman and president of Dalian Wanda Group Wang Jianlin said at a news conference of the Annual Meeting of the New Champions 2011 in Dalian, Liaoning province.

He said the focus now is the charges, and the charges could be lower, but a 'use for free' model usually end up with aged and outdated infrastructures.

Wang estimated that the tightening real estate policies would not expand to the commercial sector but only in residential sector, as the policies are to lower resident housing prices and to make them affordable.

The Annual Meeting of the New Champions 2011 opened on Sept 14 in Dalian, Liaoning province, and will end on Sept 16.
