我国现行的电力系统等份额调度方式因其对电力系统运行的负面影响而备受诟病，它涉及到能源安全、环境可持续性和可承受性等问题。为给正在进行的电力市场改革提供参考，本文采用优化模型对火电部门的经济调度节约进行量化。（1）2014年我国2803台燃煤发电机组的热耗率在273.91 ~ 348.38 gce/kWh之间，不同地区的热耗率差异很大，这说明经济调度的必要性。(2)省域经济调度可节约发电用煤5.67%，其货币价值可降低2014年平均电价0.0058元/kWh。(3)从目前的调度模式向经济调度模式过渡面临三大政治和经济挑战，即运行时间不足以收回成本，电力供应过剩和地方保护主义导致的跨境交易有限，以及不同所有制类型发电机的政治经济问题。
The current equal share dispatch approach has often been criticized for its negative influence on the electricity system operation in China, which worsens the energy security, environmental sustainability and affordability problems. To provide references for the on-going electricity market reform, this study employs an optimization model to quantify the economic dispatch savings in the coal-fired power sector. Key findings are summarized as follows: (1) The heat rates of 2803 coal generators in China range from 273.91 gce/kWh to 348.38 gce/kWh units in 2014, and the great differences among these generators at different geographical areas exhibit the necessity for economic dispatch. (2) 5.67% of the coal used for power generation could be saved from economic dispatch in a provincial level, the monetary value of which can reduce the average electricity price by 0.0058 yuan/kWh in 2014. (3) Three major political and economic challenges hinder the transition from the current dispatch mode to economic dispatch, namely the insufficient running hours for cost recovery, limited cross-border trading due to electricity over-supply and local protectionism, and the political economy problems from generators of different ownership types.
