Coal used in building materials and the electric, steel and chemical industries accounted for 85 percent of overall coal consumption during the first nine months, data released by the National Energy Administration （NEA） showed.

Maintaining growth remains a top priority of the next stage of macro-regulation,and China must steadfastly implement a proactive fiscal policy and moderately relaxed monetary policy.In maintaining growth and expanding domestic consumption,China should be patient,follow the laws of economic development,and properly balance the urgent economic growth priorities with long-term sustainable development.Macro-regulation should highlight transformation of growth pattern,strategic restructuring and improvement of economic efficiency.We should implement the policies that have been alrendy issued,and make policy preparations against emerging domestic and international situations and problems.展开更多
