气价改列入“十二五”期间资源产品价格改革的主要目标之一。2010年~2012年间，我国进口气价上涨了68.8%，对外依存度到“十二五”末很可能接近40%，进口气国内销价和进口成本例挂日益严重，这也倒逼国内气价需要调整。价格例挂催化价改，天然气市场化势在必行。本文根据现状价格及市场化后的价格，分析燃料价格对于上网电价的敏感性以及对不同燃料的经济性以及环保性进行分析，对比得出适合各类燃料发展的价格区间。

Abstract:The state has promulgated , gas utilization policy in October, 2012>. Specifically to one of the main goals of the natural gas price changes included in "the price reform of resource products during the 12th Five Year Plan". In 2010 - 2012 , Chinese imports of gas prices rose 68.8%, foreign degree of dependency to " the 12th Five Year Plan " end is probably close to 40%. The domestic gas price and import cost inversion is becoming increasingly serious, which also made domestic gas prices need to be adjusted. Price inversion catalyzed price changes, natural gas marketize will be imperative. According to the present situation of the price after marketize, Analysis theprice of fuel for electricity price sensitivity and comparative analysis that is suitable for all types of fuel development price range on the different fuel economy and environmental protection.
