TIANJIN, June 1 (Xinhua) -- China's top political advisor Jia Qinglin has called for greater coordination between five north China regions -- Beijing, Tianjin, Hebei, Shanxi and Inner Mongolia -- in order to spur national economic development.

Jia, chairman of the National Committee of the Chinese People's Political Consultative Conference (CPPCC), told a forum for regional economic development Monday that regional economic development should be coordinated nationwide.

This could be done by improving innovation ability, advancing key sciences and technologies, and establishing more innovation centers and research transformation bases.

To promote regional development, efforts were also needed to optimize industrial structure and layout, to develop cultural industries and to set up a modern industrial system characterized by high-end manufacturing and advanced services, Jia said.

Improved infrastructure and ecological environments, as well as modern transportation systems, were important guarantees to regional development, Jia said.

He called for efforts to deal with unbalanced regional development, by giving preferential policies and government support to rural and less-developed areas.

In addition, reforms in administration, finance, taxation and social management were needed for a more healthy development for private investment, Jia said.
