If the various strategic incomes are taken into consideration, the income of coal industry would amount to half of the provincial revenue. In most of the coal mining counties and cities, the coal production is the main source of their fiscal revenue and income of the residents.Governor Liu also talked about the negative effect that has been brought about to a sustainable, rapid and healthy development of Shanxi’s economy by the seriously unbalanced economic structure. Shanxi has already realized it and is setting ahout to adjust its economic structure, - the most important job to do in the "Nine Year Plan" of the province, he said. In recent years, work has been done in adjustment of e`1onomic structure and remarkable success has been achieved in certain cities, regions and in some industries.However, generally speaking, the newly-developed pillar industries are still being shaped. It will be the key to Shanxi’s economic structure adjustment to support the development of advantagous products, to find new startinrpoints of economic development and to carry out the strategy of manifold pillar industries.展开更多
