China and the United States need to invent a real economic engine to power their growth, while the current infrastructure-based stimulus packages are only short-term fixes, a top executive of a leading statistical research service company has said.

"The stimulus packages are just Band-Aids. We will not go on to the next high level of development until real growth is created through innovation of products and technologies," said Jim Clifton, chairman and CEO, Gallup.

The Washington-based Gallup is known for its public opinion polls in the United States and more than 140 countries.
