Chinese Premier Wen Jiabao has said accelerating the transformation of China's economic growth pattern is a task of great urgency for the country's development.

Wen said this on Oct. 15 in an explanation of the Proposal on Formulating the Twelfth Five-Year Program (2011-2015) on National Economic and Social Development. The Proposal was adopted at the Fifth Plenary Session of the 17th CPC Central Committee that ended Oct. 18.

Wen said the five-year period from 2011 to 2015 is a crucial time for China to build a moderately prosperous society in an all-around way, deepen the reform and opening-up and accelerate the transformation of the economic development pattern.

Wen said some problems that have made China's development unbalanced, uncoordinated and unsustainable were: resource and environment bottlenecks, the widening income gap, weakness in technological innovation, unbalanced industrial structure and unbalanced development between cities and the countryside.

Accelerating the transformation of the economic growth mode would help push the country's economic and social development up to a new level during the 12th Five-Year-Plan period, he said.

Wen called the move "a profound reform in the country's economic and social development," which demanded unswerving efforts.

He also noted, in the coming five years to 2015, it was a primary task to consolidate and expand the achievements China has made while countering the adverse effects of the global financial crisis.

Work must be done to balance the relationship between ensuring stable and relatively fast economic development, adjusting economic structure and avoiding possible inflation, he said.
